It has been determined that the installation of all -way stop controls for this intersection are appropriate for assignment of vehicular right-of-way. In support of this finding as an input for the stop sign analysis, the speed limits on Moffett Drive also need to be adopted which is based on an engineering and traffic survey as required by the California Vehicle Code (CVC). RECOMMENDATION It is recommended that the City Council adopt Resolution No. 23-55, establishing Prima Facie Speed Limits on Moffett Drive, and Resolution No. 23-56, authorizing the installation of all -way stop controls at the intersection of Moffett Drive and Windrow Road. FISCAL IMPACT It is estimated that the cost to install speed limit signs, "stop" signs, "stop ahead" signs, and appropriate pavement markings on Moffett Drive and at Moffett Drive/Windrow Road intersection is approximately $2,000. Adequate funds have been budgeted and appropriated in the FY 2023-24 operating budget for the Engineering Division. CORRELATION TO THE STRATEGIC PLAN The all -way stop traffic control measure contributes to the fulfillment of the City's Strategic Plan Goal B: Public Safety and Protection of Assets. Specifically, the project implements or fosters the implementation of strategy #5, which among other items, is to ensure continuous maintenance and improvement of traffic control and transportation facilities. BACKGROUND Moffett Drive serves as a local collector road for the surrounding existing and future residential communities. It connects to Tustin Ranch Road to the west and Harvard Avenue to the east. There are existing traffic signals at the intersections of Park Avenue and Meridian Way -Sonora Street. Windrow Road currently forms a "T" intersection at Moffett Drive but is anticipated to become a four - legged intersection as development to the north occurs.

The warrants are consistent with the California Manual on Uniform Traffic Control Devices (CA-MUTCD) and are one means of justifying the installation of stop signs. They require evaluation of numerical data collected at the subject location, including speeds, traffic volumes and accident data. To fully analyze a location for the installation of stop controls, roadway characteristics and traffic conditions need to be evaluated on a case -by -case basis. Pursuant to the California Vehicle Code (CVC), the City has the ability to establish prima facie speed limits on City streets on the basis of an engineering and traffic survey. CVC Section 627 indicates that an engineering and traffic survey needs to be conducted in accordance with methods determined by the California Department of Transportation (Caltrans) and shall include, among other requirements, consideration of all of the following: 1. Prevailing speeds as determined by traffic engineering measurements; 2. Accident records; and 3. Highway, traffic, and roadside conditions not readily apparent to the driver. DISCUSSION The CVC requires that speed limits on City streets be justified by an engineering and traffic survey (E&TS) for police enforcement involving the use of radar or other electronic devices. Because speeds have not been officially established along Moffett Drive and speed is part of the stop sign warrant analysis, the Public Works Department with input from the Tustin Police Department, carried out an E&TS and concluded that the posted speed limit along Moffett Drive shall be 35 miles per hour (MPH). With implementation of the 35 MPH speed limit on Moffett Drive as recommended in Resolution No. 23- 55, the Public Works Department and Police Department are confident that the enforcement of the posted speed limit by radar, or other electronic means, on Moffett Drive will be upheld in the court. Therefore, staff recommends that the City Council adopt Resolution No. 23-55. Upon review of the speed information along with traffic volumes (including the number of pedestrians and cyclists), and accident data for the subject intersection, it was determined that the Caltrans warrants for stop sign installation are not satisfied. However, it has been acknowledged that local residential areas represent unique situations where engineering judgment may be utilized in determining the installation of stop signs. At Moffett Drive and Windrow Road intersection it is appropriate to analyze other roadway characteristics and traffic conditions that may provide more pertinent considerations, such as the curvature of Moffett Drive and the future extension of Windrow Road to the north. In considering the overall street system controls for the area, implementation of an all -way stop condition at Moffett Drive and Windrow Road intersection would be expected to provide a more desirable balance for the area traffic controls. In consideration of the forgoing discussion, it is concluded that the installation of all -way stop control for Moffett Drive and Windrow Road intersection is appropriate. Therefore, it is recommended that Resolution No. 23-56 be adopted to authorize Moffett Drive/Windrow Road as an all -way stop control intersection.

The overall study was conducted to comply with existing State regulations concerning the increasing or decreasing of speed limits within city boundaries. Roadways within business and residential districts have an established speed limit of 25 miles per hour, while alleys and blind intersections are 15 miles per hour. Both speed limits are designated by California law. As such they are not typically included in the study. Intermediate speed limits between 25 and 65 miles per hour may be established by local authorities based on engineering and traffic surveys. It is a common belief that posting speed limit traffic signs will influence drivers to drive at that speed; however, the facts indicate otherwise. Driver behavioral research conducted in many parts of this country over a span of several decades shows that the average driver is influenced by the appearance of the highway itself and the prevailing traffic conditions in choosing the speed at which a person drives. Recognizing this, the California Vehicle Code (CVC) requires that speed limits be established in accordance with appropriate engineering practice and methods. Excerpts from the CVC regarding regulations governing speed limits and definition of terms used in speed zone surveys are detailed in Appendix A. This report contains sufficient information to document that the conditions of the latest edition of the CVC Section 627 have been satisfied and that other conditions not readily apparent to motorists are properly identified. To legally use radar for speed enforcement, Section 40802 of the CVC requires that speed limits be established per Sections 22357 and 22358 of the CVC. The limits must be justified by an E&TS conducted within five years prior to the date of the alleged violation. However, a change in State law allows cities to extend the survey period up to seven, ten, or fourteen years depending on specific criteria'. The latest edition of the CVC has highlighted bicycle and pedestrian safety as part of the study, and this aspect was considered as a part of this report. Additionally, effective January 1, 2022, several of the CVC sections mentioned above were amended and additional sections were added related to traffic safety and speed limits. These changes to the CVC were made in accordance with Assembly Bill No. 43 (AB 43) which was approved by the State of California on October 8, 2021. AB 43 is included in Appendix A for reference. The following are some key highlights of AB 43: - Allows a prima facie speed limit of 25 mph on State highways located in any business or residential district. - Authorizes Caltrans and a local authority to declare a speed of 20 or 15 mph on State highways. Authorizes a lower speed limit on a section of highway contiguous to a business activity district. Definition of "business activity district" is identified in AB 43 text. 1 Refer to Appendix A for specific survey criteria. 2 DocuSign Envelope ID: 557DD670-3DA3-4124-8D82-13570A97468F Engineering & Traffic Survey for Speed Limit Updates - Authorizes a local authority to further reduce the speed limit beyond the 5-mph reduction after June 30, 2024, if certain conditions are met. - Extends the validity of speed surveys from 10 years to 14 years if evaluated by a registered engineer. - Local authority may, by ordinance, retain the current speed limit or restore the immediately prior speed limit if that speed limit was established with an engineering and traffic survey and if a registered engineer has evaluated the section of highway and determined that no additional general-purpose lanes have been added to the roadway since completion of the traffic survey that established the prior speed limit. The current study will verify, increase, or decrease existing speed limits along the Moffett Drive segments based on the data and results of this survey. The surveys were conducted on September 26, 2023. Spot speed surveys were taken at the two segments along Moffett Drive in conformance with the State law for conducting engineering and traffic surveys for the purpose of establishing prima facie speed limits. The data was collected perthe 2014 California Manual on Uniform Traffic Control Devices (CA MUTCD), Revision 7. Sections of the CA MUTCD detailing regulations for conducting the required "Engineering and Traffic Survey" are presented in Appendix B. The actual speed zone surveys were conducted by AGA Engineers, Inc. (AGA). A California registered traffic engineer from AGA reviewed the streets, the survey data, and the crash statistics to arrive at the recommended speed limits for each segment. 3 DocuSign Envelope ID: 557DD670-3DA3-4124-8D82-13570A97468F SO Engineering & Traffic Survey for Speed Limit Updates • SECTION 2.0 — STUDY METHODOLOGY The study involved three categories of data collection and analysis: (1) geometric and characteristic street surveillance; (2) collision rate analysis; and (3) spot speed survey. The street surveillance process used field observations to determine the existing roadway characteristics, condition and placement of signs and pavement markings, land uses, pedestrian and bicycle activity, and other roadway characteristics that may not be readily apparent to motorists. Historical collision data was obtained from the City of Tustin Police Department for the period from August 1, 2021 to July 31, 2023 (i.e., two years) for the roadway segments. The collision rate was calculated and considered in recommending the speed limit by using the average daily traffic (ADT) volumes collected by the City in 2023 and the historical collision data. Spot speed surveys, utilizing a calibrated radar gun, were conducted at the two segment locations to determine existing vehicular travel speeds. A copy of the "Traffic Radar Certification" is provided in Appendix C. Typically, a minimum of 100 observations were recorded, 50 for each direction of travel, on all the streets included in the study. This data was used to calculate statistical information such as the 85th percentile travel speed,10 mile per hour (mph) pace speed, percentage of vehicles within the 10-mph pace, median speed, and other pertinent data for analysis. 21 DocuSign Envelope ID: 557DD670-3DA3-4124-8D82-13570A97468F &Wt•s Engineering & Traffic Survey for Speed Limit Updates SECTION 3.0 — SURVEY RESULTS 3.1 Street Surveillance Section 213.13 "Speed Limit Signs" of the CA MUTCD (see Appendix B) states that the speed limit should be established at the nearest five mile per hour increment (rounded per standard mathematical practice) to the 85th percentile speed recorded during the spot speed survey. However, in matching existing conditions with the traffic safety needs of the community, engineering judgment may indicate the need for a further change in speed. Whenever such factors are considered to establish the speed limit, they should be documented in the speed survey or in the accompanying engineering report. The survey streets were reviewed by Mr. Ruben Perales, P.E., T.E, Vice President at AGA Engineers, Inc., who is a registered Traffic Engineer in the State of California. The roadway characteristics, location of speed limit signs, conditions not readily apparent to the driver, land use types adjoining the street (commercial, residential, school zone, parks, etc.), and type of roadway (divided, undivided, number of lanes, etc.) were recorded as part of the study. The roadway characteristics were used to determine if any physical conditions warranted consideration of a five mile per hour reduction of the recommended speed in accordance with CVC Section 627 and if roadway segments have changed since the preparation of the previous E&TS dated October 2016. The speed survey segment roadway characteristics for each segment are indicated on the Engineering and Traffic Survey Summary sheets in Appendix D. The field survey data sheets are provided in Appendix E. 3.2 Accident Rate Analysis The collision rate for each speed survey segment was determined using the most recent collision records as required by CVC Section 627. The mid -block collision totals are based on a review of the collision reports from the City of Tustin Police Department from August 1, 2021 to July 31, 2023. Subsequently, these totals were used to calculate the mid -block collision rate, which also uses ADTvolume data. The mid -block collision rate for each street surveyed was calculated in terms of "collisions per million vehicle miles traveled" (C/MVM) and is shown on the Engineering and Traffic Survey Summary Reports. The following shows a sample calculation. The rate was calculated using the following equation: Collision Rate = Number of Midblock Collisions x 106 24-hour volume x 365 x segment length x number of years The number of mid -block collisions is based on two years' collision data (August 1, 2021 to July 31, 2023), recent 24-hour traffic volume (for both directions) within the survey segment, and the segment's length given in miles. 5 DocuSign Envelope ID: 557DD670-3DA3-4124-8D82-13570A97468F &Wt•s Engineering & Traffic Survey for Speed Limit Updates Example: Segment: Moffett Drive between Tustin Ranch Road and Downs Road: Collision Rate = 2x106 3,382 x 365 x 0.52 x 2 = 1.56 C/MVM The Average Expected Collision Rate for this segment is 1.07 and is based on the "2020 Collision Data on California State Highways2. Therefore, the calculated collision rate of 1.56 is slightly above the expected rate for this segment. The results of the collision rate calculations, including the Average Expected Collision Rates for each type of roadways, are shown in Table 1 and detailed in Appendix E. The following Average Expected Collision Rates were obtained from "2020 Collision Data on California State Highways" for Orange County published by the California Department of Transportation (Caltrans): ♦ Conventional 2 lanes or less (<45 mph): 1.07 C/MVM The slightly higher than expected accident rate on Moffett Drive between Tustin Ranch Road and Downs Avenue was taken into consideration when determining the recommended speed limit. The segment between Downs Road and Harvard Avenue is considered within an acceptable range and does not call for additional consideration. Table 1.

A reasonable and effective speed limit is based on the premise that a speed limit, thus established, conforms to the actual behavior of the majority of motorists. The speed limit should typically be established at the five mph increment nearest the 85th percentile speed recorded for the surveyed segment. However, engineering judgment and other factors such as street surveillance (Section 3.1) and collision rates (Section 3.2) may indicate the need for further reduction in establishing reasonable and effective speed limits. z 2020 Collision Data on California State Highways, State of California Department of Transportation. 0 DocuSign Envelope ID: 557DD670-3DA3-4124-8D82-13570A97468F Engineering & Traffic Survey for Speed Limit Updates VO GsT�� The criteria used in conducting the radar survey are listed in Appendix B.

It should be noted that the regulations found in Appendix B also state that "the establishment of a speed limit of five mph below the 85' percentile speed should be done with great care". The factors to be considered are: - Most recent accident record (mid -block) - Roadway design speed - Safe stopping sight distance - Super -elevation - Grades - Shoulder condition - Profile condition - Intersection spacing offsets - Commercial driveway characteristics (land use) - Pedestrian traffic with and without sidewalks - Pedestrian and bicycle safety The above factors for each roadway segment surveyed are listed in the Engineering and Traffic Survey Summary sheets in Appendix D. The 85th percentile speed and the above factors were considered in verifying existing speed limits and recommending speed limit changes (increase or decrease). The Moffett Drive Speed Zone Survey— Accident Survey Analysis (Table 1) lists the total number of accidents, calculated accident rate, and the expected accident rate. Table 2 below shows the surveyed road segments with posted and recommended speed limits. California Vehicle Code sections are defined in Appendix A. Table 2.

The maximum speed limit on most California highways is 65 mph. However, drivers are permitted to travel 70 mph where posted as such. Unless otherwise posted, the maximum speed limit in California is 55 mph on two-lane undivided highways and for vehicles towing trailers — provided the street is not within a business or residential district. Consequently, speed limit signs covering these prima facie conditions need not be posted on city streets. 0 DocuSign Envelope ID: 557DD670-3DA3-4124-8D82-13570A97468F &Wt•s Engineering & Traffic Survey for Speed Limit Updates Although not required by law, speed limit signs for these limits can be posted by a jurisdiction when an engineer determines doing so would enhance public awareness and compliance of the basic speed law. Typically, such postings occur upon streets that have the following: - Significant daily vehicular traffic volumes - Cut -through traffic problems - Significant grades - Continued violation of 25 mph speed zones - Safe stopping sight distance - Commercial driveway characteristics (land use) - Other unusual characteristics It is standard engineering practice to recommend the posting of speed limit signs only on streets that have specific speed limits enacted by city ordinance or determined to be justified by an engineer who has performed an E&TS. When an E&TS shows that the statutory or prima facie speed limits are not applicable for the existing conditions, the speed limits can be altered with the posting of a different speed limit, which must be determined according to the findings of the study. CVC Section 22354 covers decreasing highway speeds from 65 mph, and CVC Section 22358 addresses decreasing local speed limits. The CVC does not address decreasing the speed limit below 55 mph on undivided highways; however, the CA MUTCD statesthat speed zones (other than statutory speed limits) shall only be established based on an E&TS that has been performed in accordance with traffic engineering practices. Even though it is not codified in the CVC, Caltrans has established the practice of using an E&TS for any reduction below a statutory 55 mph speed limit. Law enforcement agencies and courts are accustomed to seeing surveys for these areas and it may be difficult to defend a speed violation citation without one. Speed limit signs should be installed at approximately every one-half mile on streets which have been speed zoned. Signs are typically installed at the beginning of the speed zone on the departure side of a traffic signal -controlled intersection. It is also advisable to install signs at key intersections where there is high side street vehicle entry. It is important that motorists be given adequate notice of the speed limit without over signing, since doing so increases maintenance costs and rarely results in increased compliance. The CA MUTCD outlines speed limit sign size specifications based on the type of roadway facility. Sign sizes vary from a minimum of 24-inches by 30-inches on a single lane conventional roadway to 48-inches by 60-inches on a freeway. It is also important to post signs in a manner that they are clearly visible to approaching traffic from a distance. Care should be taken to maintain landscaping and other vegetation, so it does not grow to block the motorist's view of the signs. In certain circumstances, when an engineer has determined that additional motorist awareness of the speed limit is needed, the speed limit can also be painted on the roadway surface immediately adjacent to a speed limit sign. Enforcement problems can occur when, (a) the highway is posted with inappropriate speed limit signs, (b) the highway is improperly or inadequately posted, or (c) the highway is not posted nor covered by ordinance and therefore falls under the basic speed law. In any of these events, the result is a debatable validity that may be questioned in court cases where citations are issued and contested. 9 DocuSign Envelope ID: 557DD670-3DA3-4124-8D82-13570A97468F • Engineering & Traffic Survey for Speed Limit Updates SECTION 5.0 - SUMMARY AND CONCLUSIONS An engineering speed study was conducted per CVC Section 627 and includes documentation of existing roadway conditions, radar spot speed surveys, and midblock collision analysis. A total of 2 roadway segments along Moffett Drive were surveyed. The collision rate for these segments is well below the expected collision rates published by the State of California for roadways within Orange County. Based on the radar speed survey, collision history, and field conditions, it is recommended that the existing speed limits on Moffett Drive be updated as follows: Speed Limit Increases ♦ Moffett Drive between Tustin Ranch Road and Downs Road, it is recommended that the existing speed limit of 25 mph be increased to a speed limit of 35 mph. Based on the 85t" percentile speed of 42 mph, the speed limit should be set at 40 mph, however, due to the reduced sight distance at Windrow Road and the higher than expected accident rate, a reduction of 5 mph is justified for this segment. ♦ Moffett Drive between Downs Road and Harvard Avenue, it is recommended that the existing speed limit of 25 mph be increased to a speed limit of 35 mph. Based on the 85t" percentile speed of 41 mph, the speed limit should be set at 40 mph, however, due to the narrow roadway near the Peters Canyon Trail and the presence of bike lanes a reduction of 5 mph is justified for this segment. 10 DocuSign Envelope ID: 557DD670-3DA3-4124-8D82-13570A97468F APPENDIX Regulations Governing Speed Limits and Definition of Terms Excerpts from California Vehicle Code Assembly Bill 43 (AB 43) DocuSign Envelope ID: 557DD670-3DA3-4124-8D82-13570A97468F V"Engineers, RADAR SPEED ZONE SURVEYS September 2020 Introduction This report presents the results of a traffic and engineering study for establishment of speed limits on city streets as required by Sections 22357 and 22358 of the California Vehicle Code. The review included radar surveys of prevailing vehicle speeds at various locations along the length of each street, recent traffic counts and an analysis of reported traffic accidents recorded during the specific interval. In order to enforce speed limits by radar or other electronic devices, a study must be conducted every five years. Section 40802 of the California Vehicle Code defines a speed limit enforced by radar and "....which speed limit is not justified by an engineering and traffic survey conducted within five years prior to the date of the alleged violation..." constitutes a speed trap, unless the following criteria are met: If officers have completed specialized training courses that are approved by the Commission on Peace Officer Standards Training, the time span between studies can be extended to seven years. If after seven years, "...a registered engineer evaluates the section of the highway and determines that no significant changes in roadway or traffic conditions have occurred, including, but not limited to, changes in adjoining property or land use, roadway width, or traffic volume..." the time span between studies can be extended to ten years. Since speed traps are illegal, the lack of an adequate study effectively precludes the police from using radar enforcement. Through adoption of this study, the police department will be able to enforce posted speed limits with radar equipment. It is a common belief that posting of speed limit traffic signs will influence drivers to drive at that speed. The facts indicate otherwise. Driver behavior research conducted in many parts of this country, over a span of several decades; shows that the average driver is influenced by the appearance of the highway itself and the prevailing traffic conditions, in choosing the speed at which he or she drives. Recognizing this, the California Vehicle Code requires that speed limits be established in accordance with appropriate engineering practice and methods. Regulations Governing Speed Limits Under California law, the maximum speed limit for any passenger vehicle is 65 miles per hour (mph). All other speed limits are called prima facie limits which "on the face of it", are safe and prudent under normal conditions. Certain prima facie limits are established by law and include the 25 miles per hour limit in business and residential districts (CVC515); the 15 miles per hour limit in alleys, at blind intersections, and blind railroad grade crossings; and a part-time 25 miles per hour in school zones when children are going to and from school. AGA Engineers, Inc. 211 Imperial Highway, Suite 208, Fullerton, CA 92835 (714) 992-4592 Email: aga@agaengineersinc.com DocuSign Envelope ID: 557DD670-3DA3-4124-8D82-13570A97468F Radar Speed Zone Surveys Page 2 Intermediate speed limits between 25 and 65 miles per hour may be established by local authorities based on traffic engineering surveys. Such surveys include the analysis of roadway conditions, accident records, and the prevailing speed of prudent drivers using the highway under study. If speed limits are established below what the majority of drivers consider reasonable, they are often not obeyed and consequently, are difficult to enforce. Those drivers who do not comply with posted reasonable speed limits are, conversely, subject to equitable enforcement action. The California Vehicle Code provides that the use of radar to enforce speed limits, which have not been based on a traffic and engineering study within the preceding five years, constitutes a "speed trap". Since speed traps are also prohibited by the code, lack of the required study effectively prohibits local agencies from using radar enforcement. Applicable Vehicle Code Sections Business District 235. A "business district: is that portion of a highway and the property contiguous thereto (a) upon one side of which highway, for a distance of 600 feet, 50 percent of more of the contiguous property fronting thereon is occupied by buildings in use for business, or (b) upon both sided of which highway, collectively, for a distance of 300 feet, 50 percent or more of the contiguous property fronting thereon is so occupied. A business district may be longer than the distance specified in this section if the above ratio of buildings in use for business to the length of the highway exists. Business and Residence District: Determination 240. In determining whether a highway is within a business or residence district, the following limitations shall apply and shall qualify the definitions Section 235 and 515: a) No building shall be counted unless its entrance faces the highway and the front of the building is within 75 feet of the roadway. b) Where a highway is physically divided into two or more roadways, only those buildings facing each roadway separately shall be counted for the purpose of determining whether the roadway is within a district. c) All churches, apartments, hotels, multiple dwelling houses, clubs and public buildings, other than schools, shall be deemed to be business structures. d) A highway or portion of a highway shall not be deemed to be within a district regardless of the number of buildings upon the contiguous property if there is no right of access to the highway by vehicles from the contiguous property. Residence District 515. A "residence district" is that portion of a highway and the property contiguous thereto, other than a business district, (a) upon one side of which highway, within a distance of a quarter of a mile, the contiguous property fronting thereon is occupied by 13 or more separate dwelling houses or business structures, or (b) upon both sided of which highway, collectively, within a distance of a quarter of a mile, the contiguous property fronting thereon is occupied by 16 or more separate dwelling housed or business structures. A residence district may be longer than one quarter of a mile if the above ratio of separate dwelling houses or business structures to the length of the highway exists. Engineering and Traffic Survey 627. (a) "Engineering and traffic survey" as used in this Code, means a survey of highway and traffic DocuSign Envelope ID: 557DD670-3DA3-4124-8D82-13570A97468F Radar Speed Zone Surveys Page 3 conditions in accordance with methods determined by the Department of Transportation for use by the state and local authorities. (b) An engineering and traffic survey shall include, among other requirements deemed necessary by the department, consideration of all the following: 1) Prevailing speeds as determined by traffic engineering measurements. 2) Accident records. 3) Highway, traffic, and roadside conditions not readily apparent to the driver. (c) When conducting an engineering and traffic survey, local authorities, in addition to the factors set forth in paragraphs (1) to (3), inclusive, of subdivision (b) may consider all of the following: 1) Residential density, if any of the following conditions exist on the particular portion of highway and the property contiguous thereto, other than a business district: (A) Upon one side of the highway, within a distance of a quarter of a mile, the contiguous property fronting thereon is occupied by 13 or more separate dwelling houses or business structures. (B) Upon both sides of the highway, collectively, within a distance of a quarter of a mile, the contiguous property fronting thereon is occupied by 16 or more separate dwelling houses or business structures. (C) The portion of highway is longer than one -quarter of a mile but has the ratio of separate dwelling houses or business structures to the length of the highway described in either subparagraph (A) or (B). 2) Pedestrian and bicyclist safety. Rounding Speed Limit to the Nearest 5 mph of the 85th Percentile 21400. (a) (1) The Department of Transportation shall, after consultation with local agencies and public hearings, adopt rules and regulations prescribing uniform standards and specifications for all official traffic control devices placed pursuant to this code, including, but not limited to, stop signs, yield right-of-way signs, speed restriction signs, railroad warning approach signs, street name signs, lines and markings on the roadway, and stock crossing signs placed pursuant to Section 21364. (2) The Department of Transportation shall, after notice and public hearing, determine and publicize the specifications for uniform types of warning signs, lights, and devices to be placed upon a highway by a person engaged in performing work that interferes with or endangers the safe movement of traffic upon that highway. (3) Only those signs, lights, and devices as are provided for in this section shall be placed upon a highway to warn traffic of work that is being performed on the highway. (4) Control devices or markings installed upon traffic barriers on or after January 1, 1984, shall conform to the uniform standards and specifications required by this section. (b) The Department of Transportation shall revise the California Manual on Uniform Traffic Control Devices, as it read on January 1, 2012, to require the Department of Transportation or a local authority to round speed limits to the nearest five miles per hour of the 85th percentile of the free -flowing traffic. However, in cases in which the speed limit needs to be rounded up to the nearest five miles per hour increment of the 85th-percentile speed, the Department of Transportation or a local authority may decide to instead round down the speed limit to the lower five miles per hour increment, but then the Department of Transportation or a local authority shall not reduce the speed limit any further for any reason. DocuSign Envelope ID: 557DD670-3DA3-4124-8D82-13570A97468F Radar Speed Zone Surveys Page 4 Maximum Speed Limit 22349. (a) Except as provided in Section 22356, no person shall drive a vehicle upon a highway at a speed greater than 65 miles per hour. (b) Notwithstanding any other provision of law, no person may drive a vehicle upon a two-lane, undivided highway at a speed greater than 55 miles per hour unless that highway, or portion thereof, has been posted for a higher speed by the Department of Transportation or appropriate local agency upon the basis of an engineering and traffic survey. For purposes of this subdivision, the following apply: (1) A two-lane, undivided highway is a highway with not more than one through lane of travel in each direction. (2) Passing lanes may not be considered when determining the number of through lanes. (c) It is the intent of the Legislature that there be reasonable signing on affected two-lane, undivided highways described in subdivision (b) in continuing the 55 miles -per -hour speed limit, including placing signs at county boundaries to the extent possible, and at other appropriate locations. Basic Speed Law 22350. No person shall drive a vehicle upon a highway at a speed greater than is reasonable or prudent having due regard for weather, visibility, the traffic on, and surface and width of, the highway, and in no event at a speed which endangers the safety of persons or property. Speed Law Violations 22351. (a) The speed of any vehicle upon a highway not in excess of the limits specified in Section 22352 or established as authorized in this code is lawful unless clearly proved to be in violation of the basic speed law. (b) The speed of any vehicle upon a highway in excess of the prima facie speed limits in Section 22352 or established as authorized in this code is prima facie unlawful unless the defendant establishes by competent evidence that the speed in excess of said limits did not constitute a violation of the basic speed law at the time, place and under the conditions then existing. Prima Facie Speed Limits 22352. The prima facie limits are as follows and the same shall be applicable unless changed as authorized in this code and, if so changed, only when signs have been erected giving notice thereof: (a) Fifteen miles per hour: 1) When traversing a railway grade crossing, if during the last 100 feet of the approach to the crossing the driver does not have a clear and unobstructed view of the crossing and of any traffic on the railway for a distance of 400 feet in both directions along such railway. This subdivision does not apply in the case of any railway grade crossing where a human flagman is on duty or a clearly visible electrical mechanical railway crossing signal device is installed but does not then indicate the immediate approach of a railway train or car. 2) When traversing any intersection of highways if during the last 100 feet of the driver's approach to the intersection the driver does not have a clear and unobstructed view of the intersection and of any traffic upon all of the highways entering the intersection for a distance of 100 feet along all those highways, except at an intersection protected by stop signs or yield right-of-way signs or controlled by official traffic control signals. 3) On any alley. (b) Twenty-five miles per hour: DocuSign Envelope ID: 557DD670-3DA3-4124-8D82-13570A97468F Radar Speed Zone Surveys Page 5 1) On any highway other than a state highway, in any business or residence district unless a different speed is determined by local authority under procedures set forth in this code. 2) When approaching or passing a school building or the grounds thereof, contiguous to a highway and posted with a standard "SCHOOL" warning sign, while children are going to or leaving the school either during school hours or during the noon recess period. Such prima facie limit shall also apply when approaching or passing any school grounds which are not separated from the highway by a fence, gate or other physical barrier while the grounds are in use by children and the highway is posted with a standard "SCHOOL" warning sign. For purposes of this subparagraph, standard "SCHOOL" warning signs may be placed at any distance up to 500 feet away from school grounds. 3) When passing a senior center or other facility primarily used by senior citizens, contiguous to a street other than a state highway and posted with a standard "SENIOR" warning sign. A local authority may erect a sign pursuant to this paragraph when the local agency makes a determination that the proposed signing should be implemented. A local authority may request grant funding from the Active Transportation Program pursuant to Chapter 8 (commencing with Section 2380) of Division 3 of the Streets and Highways Code, or any other grant funding available to it, and use that grant funding to pay for the erection of those signs, or may utilize any other funds available to it to pay for the erection of those signs, including, but not limited to, donations from private sources. Increase of Local Limits 22357. (a) Whenever a local authority determines upon the basis of an engineering and traffic survey that a speed greater than 25 miles per hour would facilitate the orderly movement of vehicular traffic and would be reasonable and safe upon any street other than a state highway otherwise subject to a prima facie limit of 25 miles per hour, the local authority may be by ordinance determine and declare a prima facie limit of 25 miles per hours, the local authority may by ordinance determine and declare a prima facie speed limit of 30, 35, 40, 45, 50, 55, 60 miles per hour or a maximum speed limit of 65 miles per hour, whichever is found most appropriate to facilitate the orderly movement of traffic and is reasonable and safe. The declared prima facie or maximum speed limit shall be effective when appropriate signs giving notice thereof are erected upon the street and shall not thereafter be revised except upon the basis of an engineering and traffic survey. This section does not apply to any 25-mile-per-hour prima facie limit which is applicable when passing a school building or the grounds thereof or when passing a senior center or other facility primarily used by senior citizens. Decrease of Local Limits 22358. (a) Whenever a local authority determines upon the basis of an engineering and traffic survey that the limit of 65 miles per hour is more than is reasonable or safe upon any portion of any street other than a state highway where the limit of 65 miles per hour is applicable, the local authority may by ordinance determine and declare a prima facie speed limit of 60, 55, 50, 45,40,35,30, or 25 miles per hours, whichever is found most appropriate to facilitate the orderly movement of traffic and is reasonable and safe, which declared prima facie limit shall be effective when appropriate signs giving notice thereof are erected upon the street. (b) This section shall become operative on the date specified in subdivision (c) of Section 22366. DocuSign Envelope ID: 557DD670-3DA3-4124-8D82-13570A97468F Radar Speed Zone Surveys Page 6 Decrease on Narrow Street 22358.3. Whenever a local authority determines upon the basis of an engineering and traffic survey that the prima facie speed limit of 25 miles per hour in a business or residence district or in a public park on any street having a roadway not exceeding 25 feet in width, other than a state highway, is more than is reasonable or safe, the local authority may, by ordinance or resolution, determine and declare a prima facie speed limit of 20 or 15 miles per hour, whichever is found most appropriate and is reasonable and safe. The declared prima facie limit shall be effective when appropriate signs giving notice thereof are erected upon the street. Decrease on Local Streets Near Schools or Senior Centers 22358.4. (a) (1) Whenever a local authority determines upon the basis of an engineering and traffic survey that the prima facie speed limit of 25 miles per hour established by subdivision (b) of Section 22352 is more than is reasonable or safe, the local authority may, by ordinance or resolution, determine and declare a prima facie speed limit of 20 or 15 miles per hour, whichever is justified as the appropriate speed limit by that survey. (2) An ordinance or resolution adopted under paragraph (1) shall not be effective until appropriate signs giving notice of the speed limit are erected upon the highway and, in the case of a state highway, until the ordinance is approved by the Department of Transportation and the appropriate signs are erected upon the highway. (b) (1) Notwithstanding subdivision (a) or any other provision of law, a local authority may, by ordinance or resolution, determine and declare prima facie speed limits as follows: (A) A 15 miles per hour prima facie limit in a residence district, on a highway with a posted speed limit of 30 miles per hour or slower, when approaching, at a distance of less than 500 feet from, or passing, a school building or the grounds of a school building, contiguous to a highway and posted with a school warning sign that indicates a speed limit of 15 miles per hour, while children are going to or leaving the school, either during school hours or during the noon recess period. The prima facie limit shall also apply when approaching, at a distance of less than 500 feet from, or passing, school grounds that are not separated from the highway by a fence, gate, or other physical barrier while the grounds are in use by children and the highway is posted with a school warning sign that indicates a speed limit of 15 miles per hour. (B) A 25 miles per hour prima facie limit in a residence district, on a highway with a posted speed limit of 30 miles per hour or slower, when approaching, at a distance of 500 to 1,000 feet from, a school building or the grounds thereof, contiguous to a highway and posted with a school warning sign that indicates a speed limit of 25 miles per hour, while children are going to or leaving the school, either during school hours or during the noon recess period. The prima facie limit shall also apply when approaching, at a distance of 500 to 1,000 feet from, school grounds that are not separated from the highway by a fence, gate, or other physical barrier while the grounds are in use by children and the highway is posted with a school warning sign that indicates a speed limit of 25 miles per hour. (2) The prima facie limits established under paragraph (1) apply only to highways that meet all of the following conditions: (A) A maximum of two traffic lanes. (B) A maximum posted 30 miles per hour prima facie speed limit immediately prior to and after the school zone. (3) The prima facie limits established under paragraph (1) apply to all lanes of an affected DocuSign Envelope ID: 557DD670-3DA3-4124-8D82-13570A97468F Radar Speed Zone Surveys Page 7 highway, in both directions of travel. (4) When determining the need to lower the prima facie speed limit, the local authority shall take the provisions of Section 627 into consideration. (5) (A) An ordinance or resolution adopted under paragraph (1) shall not be effective until appropriate signs giving notice of the speed limit are erected upon the highway and, in the case of a state highway, until the ordinance is approved by the Department of Transportation and the appropriate signs are erected upon the highway. (B) For purposes of subparagraph (A) of paragraph (1), school warning signs indicating a speed limit of 15 miles per hour may be placed at a distance up to 500 feet away from school grounds. (C) For purposes of subparagraph (B) of paragraph (1), school warning signs indicating a speed limit of 25 miles per hour may be placed at any distance between 500 and 1,000 feet away from the school grounds. (D) A local authority shall reimburse the Department of Transportation for all costs incurred by the department under this subdivision. Downward Speed Zoning 22358.5 It is the intent of the Legislature that physical conditions such as width, curvature, grade and surface conditions or any other condition readily apparent to a driver, in the absence of other factors, would not require special downward speed zoning, as the basic rule of Section 22350 is sufficient regulation as to such conditions. Boundary Line Streets 22359. With respect to boundary line streets and highways where portions thereof are within different jurisdictions, no ordinance adopted under Sections 22357 and 22358 shall be effective as to any such portion until all authorities having jurisdiction of the portions of the street concerned have approved the same. This section shall not apply in the case of boundary line streets consisting of separate roadways within different jurisdictions. Multiple -Lane Highways 22361. On multiple -lane highways with two or more separate roadways, different prima facie speed limits may be established for different roadways under any of the procedures specified in Sections 22354 to 22359, inclusive. Speed Trap Prohibition 40801. No peace officer or other person shall use a speed trap in arresting, or participating or assisting in the arrest of, any person for any alleged violation of this code nor shall any speed trap be used in securing evidence as to the speed of any vehicle for the purpose of an arrest or prosecution under this code. Speed Trap 40802. (a) A "speed trap" is either of the following: (1) A particular section of a highway measured as to distance and with boundaries marked, designated, or otherwise determined in order that the speed of a vehicle may be calculated by securing the time it takes the vehicle to travel the known distance. (2) A particular section of a highway with a prima facie speed limit provided by this code or by local ordinance pursuant to paragraph (1) of subdivision (b) of Section 22352, or established under Section 22354, 22357, 22358, or 22358.3, if that prima facie speed DocuSign Envelope ID: 557DD670-3DA3-4124-8D82-13570A97468F Radar Speed Zone Surveys Page 8 limit is not justified by an engineering and traffic survey conducted within five years prior to the date of the alleged violation, and enforcement of the speed limit involves the use of radar or any other electronic devices which measures the speed of moving objects. This subdivision does not apply to local street, road, or school zone. (b) (1) For purposes of this section, a local street or road is one that is functionally classified as "local" on the "California Road System Maps" that are approved by the Federal Highway Administration and maintained by the Department of Transportation. When a street or road does not appear on the "California Road System Maps," it may be defined as a "local street or road" if it primarily provides access to abutting residential property and meets the following three conditions: (A) Roadway width of not more than 40 feet. (B) Not more than one-half mile of uninterrupted length. Interruptions shall include official traffic control devices as defined in Section 445. (C) Not more than one traffic lane in each direction. (2) For purposes of this section, "school zone" means that area approaching or passing a school building or the grounds thereof that is contiguous to a highway and on which is posted a standard "SCHOOL" warning sign, while children are going to or leaving the school either during school hours or during the noon recess period. "School zone" also includes the area approaching or passing any school grounds that are not separated from the highway by a fence, gate, or other physical barrier while the grounds are in use by children if that highway is posted with a standard "SCHOOL" warning sign. (c) (1) When all of the following criteria are met, paragraph (2) of this subdivision shall be applicable and subdivision (a) shall not be applicable: (A) When radar is used, the arresting officer has successfully completed a radar operator course of not less than 24 hours on the use of police traffic radar, and the course was approved and certified by the Commission on Peace Officer Standards and Training. (B) When laser or any other electronic device is used to measure the speed of moving objects, the arresting officer has successfully completed the training required in subparagraph (A) and an additional training course of not less than two hours approved and certified by the Commission on Peace Officer Standards and Training. (C) (i) The prosecution proved that the arresting officer complied with subparagraphs (A) and (B) and that an engineering and traffic survey has been conducted in accordance with subparagraph (B) of paragraph (2). The prosecution proved that, prior to the officer issuing the notice to appear, the arresting officer established that the radar, laser, or other electronic device conformed to the requirements of subparagraph (D). (ii) The prosecution proved the speed of the accused was unsafe for the conditions present at the time of alleged violation unless the citation was for a violation of Section 223469, 22356, or 22406. (D) The radar, laser, or other electronic device used to measure the speed of the accused meets or exceeds the minimal operational standards of the National Traffic Highway Safety Administration, and has been calibrated within the three years prior to the date of the alleged violation by an independent certified laser or radar repair and testing or calibration facility. (2) A "speed trap" is either of the following: DocuSign Envelope ID: 557DD670-3DA3-4124-8D82-13570A97468F Radar Speed Zone Surveys Page 9 (A) A particular section of a highway measured as to distance and with boundaries marked, designated, or otherwise determined in order that the speed of a vehicle may be calculated by securing the time it takes the vehicle to travel the known distance. (B) (i) A particular section of a highway or state highway with a prima facie speed limit that is provided by this code or by local ordinance under paragraph (1) of subdivision (b) of Section 22352, or established under Section 22354, 22357, 22358, or 22358.3, if that prima facie speed limit is not justified by an engineering and traffic survey conducted within one of the following time periods, prior to the date of the alleged violation, and enforcement of the speed limit involves the use of radar or any other electronic device that measures the speed of moving objects: (1) Except as specified in subdause (II), seven years. (II) If an engineering and traffic survey was conducted more than seven years prior to the date of the alleged violation, and a registered engineer evaluates the section of the highway and determines that no significant changes in roadway or traffic conditions have occurred, including, but not limited to, changes in adjoining property or land use, roadway width, or traffic volume, 10 years. (ii) This subparagraph does not apply to a local street, road, or school zone. Speed Trap Evidence. 40803. (a) No evidence as to the speed of a vehicle upon a highway shall be admitted in any court upon the trial of any person in any prosecution under this code upon a charge involving the speed of a vehicle when the evidence is based upon or obtained from or by the maintenance or use of a speed trap (b) In any prosecution under this code of a charge involving the speed of a vehicle, where enforcement involves the use of radar or other electronic devices which measure the speed of moving objects, the prosecution shall establish, as part of its prima facie case, that the evidence or testimony presented is not based upon a speed trap as defined in paragraph (2) of subdivision (b) of Section 40802. (c) When a traffic and engineering survey is required pursuant to paragraph (2) of subdivision (b) of Section 40802, evidence that a traffic and engineering survey has been conducted within five years of the date of the alleged violation or evidence that the offense was committed on a local street or road as defined in paragraph (2) of subdivision (b) of Section 40802 shall constitute a prima facie case that the evidence or testimony is not based upon a speed trap as defined in paragraph (2) of subdivision (b) 40802. Study Method Speed zones are established to inform drivers of the safe speed limit and to protect the general public from unreasonable and reckless drivers. Research has shown that most drivers travel at speeds that are safe and reasonable, therefore, speed limits are established primarily on the consensus of the majority of those who use the roads. Speed limits are not based on the actions of few. The California Vehicle Code requires the limits to be established on the basis of an engineering and traffic survey rather than by arbitrary methods. DocuSign Envelope ID: 557DD670-3DA3-4124-8D82-13570A97468F Radar Speed Zone Surveys Page 10 The study is conducted in accordance with the appropriate sections of the California Vehicle Code and the California Manual on Uniform Traffic Control Devices (CA MUTCD), Section 213-13, Speed Limit Sign (R2-D) Surveys are conducted on arterial streets, collector streets, and selected local streets. Each of the selected streets was analyzed individually. The accident analysis was based on a review of the City's Traffic Accident Records (Crossroads). Only non -intersection accidents are included since intersection accidents are considered correctable using conventional intersection traffic controls such as stop signs or traffic signals. Accident rates were computed using a formula that takes into account the number of accidents in the two-year period, the length of roadway being studied, and the average daily traffic volume. The rate is expressed in accidents per million vehicle miles (Acc/MVM). The formula is: Acc/MM = Number of Accidents x 1,000,000 Distance x ADT x No. of Days In order to evaluate the accident rates for each street segment, the average rate for all surveyed street segments was calculated. Average rates were calculated for two-lane and four -or -more -lane arterial streets, two-lane collector and two-lane local streets. The accident rates for each segment were compared to the state-wide average rates for streets with similar characteristics. Definitions of Terms Average Daily Traffic Volume of traffic during a 24-hour period. ECL Easterly City Limit (also WCL, NCL and SCL for Westerly, Northerly and Southerly). 85th Percentile (Critical Speed) The "speed" which 85% of the observed vehicles are not exceeding. This speed is usually within 2 mph of the upper limit of the speed. Mean Speed The average speed. MPH or mph Miles Per Hour. MVM or mvm Million Vehicle Miles. Accident rates are generally expressed as the number of accidents occurring per million vehicle miles traveled during a given time period. Pace The 10 mph range of observed vehicle speeds containing the largest number of vehicles. A normal distribution will contain approximately 70% of the sample within the pace, with 15% above and 15% below.

Approved by Governor October 08, 2021. Filed with Secretary of State October 08, 2021. LEGISLATIVE COUNSEL'S DIGEST AB 43, Friedman. Traffic safety. (1) Existing law establishes various default speed limits for vehicles upon highways, as specified. Existing law authorizes state and local authorities to adjust these default speed limits, as specified, based upon certain findings determined by an engineering and traffic survey. Existing law defines an engineering and traffic survey and prescribes specified factors that must be included in the survey, including prevailing speeds and road conditions. Existing law authorizes local authorities to consider additional factors, including pedestrian and bicyclist safety. This bill would authorize local authorities to consider the safety of vulnerable pedestrian groups, as specified. (2) Existing law establishes a prima facie speed limit of 25 miles per hour on any highway, other than a state highway, located in any business or residence district, as defined. Existing law authorizes a local authority to change the speed limit on any such highway, as prescribed, including erecting signs to give notice thereof. This bill would establish a prima facie speed limit of 25 miles per hour on state highways located in any business or residence district and would authorize the Department of Transportation (Caltrans) to change the speed limit on any such highway, as prescribed, including erecting signs to give notice thereof. (3) Existing law establishes a speed limit of 65 miles per hour on state highways, as specified. Existing law authorizes Caltrans to declare a speed limit on any such highway, as prescribed, of 60, 55, 50, 45, 40, 35, 30, or 25 miles per hour, including erecting signs to give notice thereof. Existing law also authorizes a local authority, on a section of highway, other than a state highway, where the speed limit is 65 miles per hour to declare a lower speed limit, as specified. This bill would additionally authorize Caltrans and a local authority to declare a speed limit of 20 or 15 miles per hour, as specified, on these highways. (4) Existing law authorizes a local authority, without an engineering and traffic survey, to declare a lowered speed limit on portions of highway, as specified, approaching a school building or school grounds.

This bill would similarly authorize a lowered speed limit on a section of highway contiguous to a business activity district, as defined, and would require that certain violations be subject to a warning citation, for the first 30 days of implementation. (5) Existing law requires Caltrans, by regulation, to provide for the rounding up or down to the nearest 5 miles per hour increment of the 85th percentile speed of free -flowing traffic on a portion of highway as determined by a traffic and engineering survey. Existing law requires the Judicial Council to create and implement an online tool by June 30, 2024, for the adjudication of traffic infractions, among other things. This bill would authorize a local authority to further reduce the speed limit, as specified, and require that certain violations be subject to a warning citation, for the first 30 days of implementation. The bill would, in some circumstances, authorize the reduction of a speed limit beginning June 30, 2024, or when the Judicial Council has developed an online tool for adjudicating traffic infraction violations, whichever is sooner. The bill would require Caltrans to accordingly revise the California Manual on Uniform Traffic Control Devices, as specified. (6) Existing law defines a speed trap and prohibits evidence of a driver's speed obtained through a speed trap from being admissible in court in any prosecution against a driver for a speed -related offense. Existing law deems a road where the speed limit is not justified by a traffic and engineering survey conducted within the previous 7 years to be a speed trap, unless the roadway has been evaluated by a registered engineer, as specified, in which case the speed limit remains enforceable for a period of 10 years. Existing law exempts a school zone, as defined, from certain provisions relating to defining a speed trap. This bill would extend the period that a speed limit justified by a traffic and engineering survey conducted more the 7 years ago remains valid, for purposes of speed enforcement, if evaluated by a registered engineer, as specified, to 14 years. This bill would also exempt a senior zone and business activity district, as defined, from those provisions.

SEC. 4. Section 22354 of the Vehicle Code is amended to read: 22354. (a) Whenever the Department of Transportation determines upon the basis of an engineering and traffic survey that the limit of 65 miles per hour is more than is reasonable or safe upon any portion of a state highway where the limit of 65 miles is applicable, the department may determine and declare a prima facie speed limit of 60, 55, 50, 45, 40, 35, 30, 25, 20, or 15 miles per hour, whichever is found most appropriate to facilitate the orderly movement of traffic and is reasonable and safe, which declared prima facie speed limit shall be effective when appropriate signs giving notice thereof are erected upon the highway. (b) This section shall become operative on the date specified in subdivision (c) of Section 22366. SEC. 5. Section 22358 of the Vehicle Code is amended to read: 22358. (a) Whenever a local authority determines upon the basis of an engineering and traffic survey that the limit of 65 miles per hour is more than is reasonable or safe upon any portion of any street other than a state highway where the limit of 65 miles per hour is applicable, the local authority may by ordinance determine and declare a prima facie speed limit of 60, 55, 50, 45, 40, 35, 30, 25, 20, or 15 miles per hour, whichever is found most appropriate to facilitate the orderly movement of traffic and is reasonable and safe, which declared prima facie limit shall be effective when appropriate signs giving notice thereof are erected upon the street. (b) This section shall become operative on the date specified in subdivision (c) of Section 22366. SEC. 6. Section 22358.6 is added to the Vehicle Code, to read: 22358.6. The Department of Transportation shall, in the next scheduled revision, revise and thereafter maintain the California Manual on Uniform Traffic Control Devices to require the Department of Transportation or a local authority to round speed limits to the nearest five miles per hour of the 85th percentile of the free -flowing traffic. However, in cases in which the speed limit needs to be rounded up to the nearest five miles per hour increment of the 85th-percentile speed, the Department of Transportation or a local authority may decide to instead round down the speed limit to the lower five miles per hour increment. A local authority may additionally lower the speed limit as provided in Sections 22358.7 and 22358.8. SEC. 7. Section 22358.7 is added to the Vehicle Code, to read: 22358.7. (a) If a local authority, after completing an engineering and traffic survey, finds that the speed limit is still more than is reasonable or safe, the local authority may, by ordinance, determine and declare a prima facie speed limit that has been reduced an additional five miles per hour for either of the following reasons: (1) The portion of highway has been designated as a safety corridor. A local authority shall not deem more than one -fifth of their streets as safety corridors. (2) The portion of highway is adjacent to any land or facility that generates high concentrations of bicyclists or pedestrians, especially those from vulnerable groups such as children, seniors, persons with disabilities, and the unhoused. (b) (1) As used in this section, "safety corridor" shall be defined by the Department of Transportation in the next revision of the California Manual on Uniform Traffic Control Devices. In making this determination, the department shall consider highways that have the highest number of serious injuries and fatalities based on collision data that may be derived from, but not limited to, the Statewide Integrated Traffic Records System. (2) The Department of Transportation shall, in the next revision of the California Manual on Uniform Traffic Control Devices, determine what constitutes land or facilities that generate high concentrations of bicyclists and pedestrians, as used in paragraph (2) of subdivision (a). In making this determination, the department shall consider density, road use type, and bicycle and pedestrian infrastructure present on a section of highway. (c) A local authority may not lower a speed limit as authorized by this section until June 30, 2024, or until the Judicial Council has developed an online tool for adjudicating infraction violations statewide as specified in Article 7 (commencing with Section 68645) of Chapter 2 of Title 8 of the Government Code, whichever is sooner. (d) A local authority shall issue only warning citations for violations of exceeding the speed limit by 10 miles per hour or less for the first 30 days that a lower speed limit is in effect as authorized by this section. https://Ieginfo.legislature.ca.gov/faces/biIINavClient.xhtml?bill_id=202120220AB43 417 DocuSign Envelope ID: 557DD670-3DA3-4124-8D82-13570A97468F wi 1 elee, 7:c 1 r,rvi Bill Text - AB-43 Traffic safety. SEC. 8. Section 22358.8 is added to the Vehicle Code, to read: 22358.8. (a) If a local authority, after completing an engineering and traffic survey, finds that the speed limit is still more than is reasonable or safe, the local authority may, by ordinance, retain the current speed limit or restore the immediately prior speed limit if that speed limit was established with an engineering and traffic survey and if a registered engineer has evaluated the section of highway and determined that no additional general purpose lanes have been added to the roadway since completion of the traffic survey that established the prior speed limit. (b) This section does not authorize a speed limit to be reduced by any more than five miles per hour from the current speed limit nor below the immediately prior speed limit. (c) A local authority shall issue only warning citations for violations of exceeding the speed limit by 10 miles per hour or less for the first 30 days that a lower speed limit is in effect as authorized by this section. SEC. 9. Section 22358.9 is added to the Vehicle Code, to read: 22358.9. (a) (1) Notwithstanding any other law, a local authority may, by ordinance, determine and declare a 25 or 20 miles per hour prima facie speed limit on a highway contiguous to a business activity district when posted with a sign that indicates a speed limit of 25 or 20 miles per hour. (2) The prima facie limits established under paragraph (1) apply only to highways that meet all of the following conditions: (A) A maximum of four traffic lanes. (B) A maximum posted 30 miles per hour prima facie speed limit immediately prior to and after the business activity district, if establishing a 25 miles per hour speed limit. (C) A maximum posted 25 miles per hour prima facie speed limit immediately prior to and after the business activity district, if establishing a 20 miles per hour speed limit. (b) As used in this section, a "business activity district' is that portion of a highway and the property contiguous thereto that includes central or neighborhood downtowns, urban villages, or zoning designations that prioritize commercial land uses at the downtown or neighborhood scale and meets at least three of the following requirements in paragraphs (1) to (4), inclusive: (1) No less than 50 percent of the contiguous property fronting the highway consists of retail or dining commercial uses, including outdoor dining, that open directly onto sidewalks adjacent to the highway. (2) Parking, including parallel, diagonal, or perpendicular spaces located alongside the highway. (3) Traffic control signals or stop signs regulating traffic flow on the highway, located at intervals of no more than 600 feet. (4) Marked crosswalks not controlled by a traffic control device. (c) A local authority shall not declare a prima facie speed limit under this section on a portion of a highway where the local authority has already lowered the speed limit as permitted under Sections 22358.7 and 22358.8. (d) A local authority shall issue only warning citations for violations of exceeding the speed limit by 10 miles per hour or less for the first 30 days that a lower speed limit is in effect as authorized by this section. SEC. 10. Section 40802 of the Vehicle Code is amended to read: 40802. (a) A "speed trap" is either of the following: (1) A particular section of a highway measured as to distance and with boundaries marked, designated, or otherwise determined in order that the speed of a vehicle may be calculated by securing the time it takes the vehicle to travel the known distance. (2) A particular section of a highway with a prima facie speed limit that is provided by this code or by local ordinance under paragraph (1) of subdivision (b) of Section 22352, or established under Section 22354, 22357, 22358, or 22358.3, if that prima facie speed limit is not justified by an engineering and traffic survey conducted https://Ieginfo.legislature.ca.gov/faces/biIINavClient.xhtml?bill_id=202120220AB43 5/7 DocuSign Envelope ID: 557DD670-3DA3-4124-8D82-13570A97468F wi 1 elee, 7:c 1 r,rvi Bill Text - AB-43 Traffic safety. within five years prior to the date of the alleged violation, and enforcement of the speed limit involves the use of radar or any other electronic device that measures the speed of moving objects. This paragraph does not apply to a local street, road, school zone, senior zone, or business activity district. (b) (1) For purposes of this section, a local street or road is one that is functionally classified as "local" on the "California Road System Maps;" that are approved by the Federal Highway Administration and maintained by the Department of Transportation. It may also be defined as a "local street or road" if it primarily provides access to abutting residential property and meets the following three conditions: (A) Roadway width of not more than 40 feet.

Section 2B.13 Speed Limit Sign (R2-1) Support: oo The setting of speed limits can be controversial and requires a rational and defensible determination to maintain public confidence. Speed limits are normally set near the 85th-percentile speed that statistically represents one standard deviation above the average speed and establishes the upper limit of what is considered reasonable and prudent. As with most laws, speed limits need to depend on the voluntary compliance of the greater majority of motorists. Speed limits cannot be set arbitrarily low, as this would create violators of the majority of drivers and would not command the respect of the public. Artificially low speed limits can lead to poor compliance as well as large variations in speed within the traffic stream. Increased speed variance can also create more conflicts and passing maneuvers. ooa The most effective way to reduce speeds is through a combination of strategies using traffic control devices related to speed management, roadway design and engineering solutions, traffic calming techniques and measures, public education, and enforcement efforts. Effectively managing road user speed relies on numerous factors, which include enforcement, roadway characteristics, surrounding environment, adjacent land use, and traffic control devices. Many studies find that engineering changes, such as change a road's infrastructure, are one of the most important factors in reducing vehicle operating speeds. Engineering changes are also one of the most effective interventions at reducing pedestrian injury and Chapter 2B — Regulatory Signs, Barricades, and Gates Revised January 6, 2023 Part 2 — Signs DocuSign Envelope ID: 557DD670-3DA3-4124-8D82-13570A97468F California MUTCD 2014 Edition Page 134 (FHWA's MUTCD 2009 Edition, including Revisions 1 & 2, as amended for use in California) fatality rates. Potential street engineering changes, such as curb extensions, median islands, raised crosswalks, roundabouts, and speed bumps or speed humps, naturally result in lower speeds. It is realized that these engineering changes can be costly and time-consuming to implement. Standard: of Speed zones (other than statutory speed limits) shall only be established on the basis of an engineering and traffic survey (E&TS) stmly that has been performed in accordance with traffic engineering practices. The engineering study shall include an analysis of the current speed distribution of free -flowing vehicles. 02 The Speed Limit (R2-1) sign (see Figure 213-3) shall display the limit established by law, ordinance, regulation, or as adopted by the authorized agency based on the engineering study. The speed limits displayed shall be in multiples of 5 mph. 03 Speed Limit (R2-1) signs, indicating speed limits for which posting is required by law, shall be located at the points of change from one speed limit to another. 04 At the downstream end of the section to which a speed limit applies, a Speed Limit sign showing the next speed limit shall be installed. Additional Speed Limit signs shall be installed beyond major intersections and at other locations where it is necessary to remind road users of the speed limit that is applicable. 05 Speed Limit signs indicating the statutory speed limits shall be installed at entrances to the State and, where appropriate, at jurisdictional boundaries in urban areas. Support: 06In general, the maximum speed limits applicable to rural and urban roads are established: A. Statutorily — a maximum speed limit applicable to a particular class of road, such as freeways or city streets, that is established by State law; or B.

The portion of a highway has been designated as a safety corridor. 2. The portion of highway is adjacent to any land or facility that generates high concentrations of bicyclists or pedestrians, especially those from vulnerable groups such as children, seniors, persons with disabilities, and the unhoused. CVC Section 22358.7(a)(1) — "Safety Corridor" Definition Standard: 12n A safety corridor shall be defined as a roadway segment within an overall roadway network where the highest number of serious injury and fatality crashes occur. 12o One or more of the required crash weighting factors listed in the Table 2B-105(CA) shall be used to prioritize the locations of fatal and serious injury crashes in developing the "Safety Corridor". Option: 12p Data used to determine a safety corridor may be from the most recent Engineering and Traffic Survey (E&TS) performed. The crash data source may include, but is not limited to, California Highway Patrol's (CHP) Statewide Integrated Traffic Records System (SWITRS). Standard: 12q The prioritized subset of safety corridors shall: 1. Identify specific locations with high crash occurrences. 2. Identify corridor -level segments with a pattern of crash reoccurrence. 3. Be able to be stratified by mode. 12r Safety corridors shall represent a prioritized subset of the overall roadway network within an authority's responsibilities and shall not exceed one -fifth of the overall roadway network. Guidance: 12s A jurisdiction should use three to five years of the most recent crash data to determine a safety corridor based on Fatal and Serious Injury data. Option: 12t For crash coverage, safety corridors may identify the subset of the overall roadway network where a minimum of 25% of the Fatal + Serious Injury (F+SI) crashes occur. 12u To identify logical termini, the geographic extent of a safety corridor may be determined by non -engineering staff. Standard: 12v A licensed professional engineer shall sign off on logical termini identified for a safety corridor using existing E&TS. Option: 12w Crash/Volume rate may be used to provide additional locations to be included in the safety corridor. Local agencies may use proactive measures as indicators.

Standard: 12ab The top twenty percent of pedestrian and/or bicyclist fatalities or serious injury crashes within a three to five year period shall be based on the geographic area within the jurisdiction of the Engineer performing the E&TS. Option: 12ac A high concentration of pedestrians and bicyclists may be longer than 1320 feet provided that a minimum of one generator is present for every 1320 feet. 12ad Data used to determine high concentration locations may be obtained from the most recently performed Engineering and Traffic Survey (E&TS). Standard: 12ae The provisions of CVC Section 22358.7 to additionally lower the speed limit (by designating safety corridor or on portion of highway is adjacent to any land or facility that generates high concentrations of bicyclists or pedestrians), shall not be applicable until actions required per CVC Section 22358.7 by Department of Transportation and Judicial Council are completed or June 30, 2024, whichever is sooner. CVC Section 22358.8 (Retain currently adopted or restore immediately prior speed limit) Option: 12af Local agency may retain the currently adopted speed limit without further reduction or restore the immediately prior adopted speed limit without further reduction as provided in CVC Section 22358.8. Standard: 12ag Currently adopted speed limit or immediately prior adopted speed limit shall only be retained, by ordinance, if after completing an E&TS, local agency finds that the speed limit is still more than reasonable or safe, and that speed limit was established with an E&TS and if a registered engineer has evaluated the section of highway and determined that no additional general purpose lanes have been added to the roadway since completion of the traffic survey that established the prior speed limit. 12ah If local agency decides to use lower speed limit based on CVC Section 22358.8, after completing an E&TS and finding that the speed limit is still more than is reasonable or safe, it shall not be reduced by any more than 5 mph from the currently adopted speed limit not below the immediately prior speed limit. Refer to CVC Section 22358.8(b). CVC Section 22358.9 — Business Activitv District Option: 12ai A local authority may, by ordinance, determine and declare a 25 or 20 mph prima facie speed limit on a highway contiguous to a business activity district when posted with a sign that indicates a speed limit of 25 or 20 mph if the highway segment meets all of the following conditions: 1. A maximum of four traffic lanes. 2. A maximum posted 30 mph prima facie speed limit immediately prior to and after the business activity district, if establishing a 25 mph speed limit. 3. A maximum posted 25 mph prima facie speed limit immediately prior to and after the business activity district, if establishing a 20 mph speed limit. 12aj A "business activity district" is that portion of a highway and the property contiguous thereto that includes central or neighborhood downtowns, urban villages, or zoning designations that prioritize commercial land uses at the downtown or neighborhood scale and meets a least three of the following four requirements: 4.

Refer to CVC Section 22358.9(c). 13 Speed studies for signalized intersection approaches should be taken outside the influence area of the traffic control signal, which is generally considered to be approximately 112 mile, to avoid obtaining skewed results for the 85th percentile speed. Support: 14 Advance warning signs and other traffic control devices to attract the motorist's attention to a signalized intersection are usually more effective than a reduced speed limit zone. Guidance: is An advisory speed plaque (see Section 2C. 08) mounted below a warning sign should be used to warn road users of an advisory speed for a roadway condition. A Speed Limit sign should not be used for this situation. Option: 16 Other factors that may be considered when establishing or reevaluating speed limits are the following: A. Road characteristics, shoulder condition, grade, alignment, and sight distance; B. The pace; C. Roadside development and environment; D. Parking practices and pedestrian activity; and E. Reported crash experience for at least a 12-month period. 17 Two types of Speed Limit signs may be used: one to designate passenger car speeds, including any nighttime information or minimum speed limit that might apply; and the other to show any special speed limits for trucks and other vehicles. 18 A changeable message sign that changes the speed limit for traffic and ambient conditions may be installed provided that the appropriate speed limit is displayed at the proper times. 19 A changeable message sign that displays to approaching drivers the speed at which they are traveling may be installed in conjunction with a Speed Limit sign. Guidance: 20If a changeable message sign displaying approach speeds is installed, the legend YOUR SPEED XX MPH or such similar legend should be displayed. The color of the changeable message legend should be a yellow legend on a black background or the reverse of these colors. Support: 21 Advisory Speed signs and plaques are discussed in Sections 2C.08 and 2C.14. Temporary Traffic Control Zone Speed signs are discussed in Part 6. The WORK ZONE (G20-5aP) plaque intended for installation above a Speed Limit sign is discussed in Section 6F.12. School Speed Limit signs are discussed in Section 7B.15. 22 Speed limits in California are governed by the California Vehicle Code (CVC), Sections 22348 through 22413; also, pertinent sections are found in Sections 627 and 40802 and others referenced in this section. See Section 1A.11 for information regarding this publication. 23 Refer to Part 6, Section 6C.01 for speed limit signs in temporary traffic control zones. Refer to Part 7 for speed limit signs in school areas. Engineering and Traffic Survey_(E&TS) Support: 24 CVC Section 627 defines the term "Engineering and traffic survey" and lists its requirements. Standard: 25 An engineering and traffic survey (E&TS) shall include, among other requirements deemed necessary by Caltrans, consideration of all of the following: A. Prevailing speeds as determined by traffic engineering measurements. B. Collision records. C. Highway, traffic, and roadside conditions not readily apparent to the driver. Chapter 2B — Regulatory Signs, Barricades, and Gates Revised January 6, 2023 Part 2 — Signs DocuSign Envelope ID: 557DD670-3DA3-4124-8D82-13570A97468F California MUTCD 2014 Edition Page 139 (FHWA's MUTCD 2009 Edition, including Revisions 1 & 2, as amended for use in California) Guidance: 26 The E&TS should contain sufficient information to document that the required three items of CVC Section 627 are provided and that other conditions not readily apparent to a driver are properly identified. 27 Prevailing speeds are determined by a speed zone survey. A speed zone survey should include: A. The intent of the speed measurements is to determine the actual speed of unimpeded traffic. The speed of traffic should not be altered by concentrated law enforcement, or other means, just prior to, or while taking the speed measurements. B. Only one person is required for the field work. Speeds should be read directly from a radar or other electronic speed measuring devices; or, C. Devices, other than radar, capable of accurately distinguishing and measuring the unimpeded speed of free flowing vehicles may be used. D. A location should be selected where prevailing speeds are representative of the entire speed zone section. If speeds vary on a given route, more than one speed zone section may be required, with separate measurements for each section. Locations for measurements should be chosen so as to minimize the effects of traffic signals or stop signs. E. Speed measurements should be taken during off-peak hours between peak traffic periods on weekdays. If there is difficulty in obtaining the desired quantity, speed measurements may be taken during any period with free flowing traffic. F. The weather should be fair (dry pavement) with no unusual conditions prevailing. G. The surveyor and equipment should not affect the traffic speeds. For this reason, an unmarked car is recommended, and the radar speed meter located as inconspicuously as possible. H. In order for the sample to be representative of the actual traffic flow, the minimum sample should be 100 vehicles in each survey. In no case should the sample contain less than 50 vehicles. I. Short speed zones of less than 0.5 miles should be avoided, except in transition areas. J. Speed zone changes should be coordinated with changes in roadway conditions or roadside development. K. Speed zoning should be in 10 mph increments except in urban areas where 5 mph increments are preferable. L. Speed zoning should be coordinated with adjacent jurisdictions. Support: 28 Physical conditions such as width, curvature, grade and surface conditions, or any other condition readily apparent to the driver, in the absence of other factors, would not require special downward speed zoning. Refer to CVC 22358.5. Option: 29 When qualifying an appropriate speed limit, local authorities may also consider all of the following findings: A. Residential density, if any of the following conditions exist on the particular portion of highway and the property contiguous thereto, other than a business district: 1. Upon one side of the highway, within 0.25 miles, the contiguous property fronting thereon is occupied by 13 or more separate dwelling houses or business structures. 2. Upon both sides of the highway, collectively, within a distance of 0.25 miles the contiguous property fronting thereon is occupied by 16 or more separate dwelling houses or business structures. 3. The portion of highway is larger than 0.25 miles but has the ratio of separate dwelling houses or business structures to the length of the highway described in either subparagraph 1 or 2 above. B. Safety of bicyclists and pedestrians, with increased consideration for vulnerable pedestrian groups including children, seniors, persons with disabilities, users of personal assistive mobility devices, and the unhoused. 3o The following two methods of conducting E&TS may be used to establish speed limits: 1. State Highways - The E&TS for State highways is made under the direction of the Caltrans District Traffic Engineer. The data includes: a. One copy of the Example of Speed Zone Survey Sheet (See Figure 2B-101(CA)) showing: • A north arrow • Engineer's station or post mileage • Limits of the proposed zones • Appropriate notations showing type of roadside development, such as "scattered business," "solid residential," etc. Schools adjacent to the highway are shown, but other buildings need not be plotted unless they are a factor in the speed recommendation or the point of termination of a speed zone.

A report to the District Director that includes: • The reason for the initiation of speed zone survey. • Recommendations and supporting reasons. • The enforcement jurisdictions involved and the recommendations and opinions of those officials. • The stationing or reference post in mileage at the beginning and ending of each proposed zone and any intermediate equations. Location ties must be given to readily identifiable physical features. 2. City and County Through Highways, Arterials, Collector Roads and Local Streets. a. The short method of speed zoning is based on the premise that a reasonable speed limit is one that conforms to the actual behavior of the majority of motorists, and that by measuring motorists' speeds, one will be able to select a speed limit that is both reasonable and effective. Other factors that need to be considered include but are not limited to: the most recent two-year collision record, roadway design speed, safe stopping sight distance, superelevation, shoulder conditions, profile conditions, intersection spacing and offsets, commercial driveway characteristics, and pedestrian traffic in the roadway without sidewalks. b. Determination of Existing Speed Limits - Figures 213-103(CA) & 213-104(CA) show examples of data sheets which may be used to record speed observations. Specific types of vehicles may be tallied by use of letter symbols in appropriate squares. 31 In most situations, the short form for local streets and roads will be adequate; however, the procedure used on State highways may be used at the option of the local agency. 32 Any agency may lower the speed limit below the prima facie speed limit after performing, and based on the results of an E&TS. Guidance: 33 The establishment of a speed limit of more than 5 mph below the 851h percentile speed should be done with great care as studies have shown that establishing a speed limit at less than the 85th percentile generally results in an increase in collision rates; in addition, this may make violators of a disproportionate number of the reasonable majority of drivers. Support: 34 Generally, the most decisive evidence of conditions not readily apparent to the driver surfaces in collision histories. 35 Speed limits are established at or near the 851h percentile speed, which is defined as that speed at or below which 851h percent of the traffic is moving. The 85th percentile speed is often referred to as the critical speed. Pace speed is defined as the 10 mph increment of speed containing the largest number of vehicles (See Figure 213-102(CA)). The lower limit of the pace is plotted on the Speed Zone Survey Sheets as an aid in determining the proper zone limits. Speed limits higher than the 85th percentile are not generally considered reasonable and prudent. Speed limits below the 85th percentile do not ordinarily facilitate the orderly movement of traffic and require constant enforcement to maintain compliance. Speed limits established on the basis of the 85th percentile conform to the consensus of those who drive highways as to what speed is reasonable and prudent, and are not dependent on the judgment of one or a few individuals. 36 The majority of drivers comply with the basic speed law. Speed limits set at or near the 85th percentile speed provide law enforcement officers with a limit to cite drivers who will not conform to what the majority considers reasonable and prudent. Further studies show that establishing a speed limit at less than the 85th percentile (Critical Speed) generally results in an increase in collision rates. Option: 37 When roadside development results in traffic conflicts and unusual conditions which are not readily apparent to drivers, as indicated in collision records, speed limits somewhat below the 85th percentile may be justified. Concurrence and support of enforcement officials are necessary for the successful operation of a restricted speed zone. Guidance: 38 Speed zones of less than 0.5 miles and short transition zones should be avoided.

Standard: 82 Prima facie speed limits are specific limits and shall apply unless changed based upon an engineering and traffic survey (E&TS) and signs are posted that display the new speed limit. Option: 83 Prima facie speed limits may be preempted by the basic speed law, when roadway, traffic or weather conditions warrant a lower speed. Use of Metric System Designations — See CVC 21351.3 Option: 84 Dual units for speed limits on signs may be placed on local streets and roads in both Metric and English units. Guidance: 85 If used, dual unit speed limits should be rounded to the nearest 10 km/h for Metric and 5 mph for English units for posting on signs on local streets and roads. Support: 86 Refer to AASHTO's Traffic Engineering Metric Conversion Factors. See Section 1A.11 for information regarding this publication. Standard: 87 Metric speed limits shall not be placed on State highways. For use in this California MUTCD, 70 mph shall be shown as a metric equivalent of 110 km/h, neither of which shall be used on any local street or road. Legal Authority for Establishing Speed Limits Support: 88 Delegation of legal authority to set speed limits on State highways is given to Caltrans District Directors. The District Director of each transportation district is authorized to issue orders regulating the speed of traffic, up to 65 mph on State highways. The Director of Caltrans retains the authority to approve variable, minimum, and maximum speeds up to 70 mph on State freeways. Standard: 89 The speed limits shown in Table 213-101(CA) shall apply, unless changed upon the basis of an engineering and traffic survey (E&TS). Option: 90 The speed limits shown in Table 213-102(CA) may apply, unless changed upon E&TS. Variable Speed Limits on Freeways - See CVC 22355 Option: 91 The following speed limits may apply: • Whenever Caltrans determines based upon an engineering and traffic survey (E&TS) that the safe and orderly movement of traffic upon any freeway segment will be facilitated by the establishment of variable speed limits. • Caltrans may erect, regulate, and control signs upon the state highway which is a freeway, or any portion thereof, which, if used, signs shall be designed to permit display of different speeds at various times of the day or night. • Such signs need not conform to the standards & specifications per CVC 21400, but if used, shall be of sufficient size and clarity to give adequate notice of the applicable speed limit. Minimum Speed Limits on State Highways - See CVC 22400 Option: 92 The following speed limits may apply: • Whenever Caltrans determines based upon an engineering and traffic survey (E&TS) that slow speeds on any part of a state highway consistently impede the normal and reasonable movement of traffic, Caltrans may determine and declare a minimum speed limit. Appropriate signs giving notice shall then be installed on that segment.
