VEHICLE CODE
SECTION 35400-35414
35400. (a) A vehicle may not exceed a length of 40 feet. (b) This section does not apply to any of the following: (1) A vehicle used in a combination of vehicles when the excess length is caused by auxiliary parts, equipment, or machinery not used as space to carry any part of the load, except that the combination of vehicles shall not exceed the length provided for combination vehicles. (2) A vehicle, when the excess length is caused by any parts necessary to comply with the fender and mudguard regulations of this code. (3) (A) An articulated bus or articulated trolley coach that does not exceed a length of 60 feet. (B) An articulated bus or articulated trolley coach described in subparagraph (A) may be equipped with a folding device attached to the front of the bus or trolley if the device is designed and used exclusively for transporting bicycles. The device, including any bicycles transported thereon, shall be mounted in a manner that does not materially affect efficiency or visibility of vehicle safety equipment, and shall not extend more than 36 inches from the front body of the bus or trolley coach when fully deployed. The handlebars of a bicycle that is transported on a device described in this subparagraph shall not extend more than 42 inches from the front of the bus. (4) A semitrailer while being towed by a motortruck or truck tractor, if the distance from the kingpin to the rearmost axle of the semitrailer does not exceed 40 feet for semitrailers having two or more axles, or 38 feet for semitrailers having one axle if the semitrailer does not, exclusive of attachments, extend forward of the rear of the cab of the motortruck or truck tractor. (5) A bus or house car when the excess length is caused by the projection of a front safety bumper or a rear safety bumper, or both. The safety bumper shall not cause the length of the vehicle to exceed the maximum legal limit by more than one foot in the front and one foot in the rear. For the purposes of this chapter, "safety bumper" means any device that is fitted on an existing bumper or which replaces the bumper and is constructed, treated, or manufactured to absorb energy upon impact. (6) A schoolbus, when the excess length is caused by the projection of a crossing control arm. For the purposes of this chapter, "crossing control arm" means an extendable and retractable device fitted to the front of a schoolbus that is designed to impede movement of pupils exiting the schoolbus directly in front of the schoolbus so that pupils are visible to the driver while they are moving in front of the schoolbus. An operator of a schoolbus shall not extend a crossing control arm while the schoolbus is in motion. Except when activated, a crossing control arm shall not cause the maximum length of the schoolbus to be extended by more than 10 inches, inclusive of any front safety bumper. Use of a crossing control arm by the operator of a schoolbus does not, in and of itself, fulfill his or her responsibility to ensure the safety of students crossing a highway or private road pursuant to Section 22112. (7) A bus, when the excess length is caused by a device, located in front of the front axle, for lifting wheelchairs into the bus. That device shall not cause the length of the bus to be extended by more than 18 inches, inclusive of any front safety bumper. (8) A bus, when the excess length is caused by a device attached to the rear of the bus designed and used exclusively for the transporting of bicycles. This device may be up to 10 feet in length, if the device, along with any other device permitted pursuant to this section, does not cause the total length of the bus, including any device or load, to exceed 50 feet. (9) A bus operated by a public agency or a passenger stage corporation, as defined in Section 226 of the Public Utilities Code, used in transit system service, other than a schoolbus, when the excess length is caused by a folding device attached to the front of the bus which is designed and used exclusively for transporting bicycles. The device, including any bicycles transported thereon, shall be mounted in a manner that does not materially affect efficiency or visibility of vehicle safety equipment, and shall not extend more than 36 inches from the front body of the bus when fully deployed. The handlebars of a bicycle that is transported on a device described in this paragraph shall not extend more than 42 inches from the front of the bus. A device described in this paragraph may not be used on a bus that, exclusive of the device, exceeds 40 feet in length or on a bus having a device attached to the rear of the bus pursuant to paragraph (8). (10) (A) A bus of a length of up to 45 feet when operating on those highways specified in subdivision (a) of Section 35401.5. The Department of Transportation or local authorities, with respect to highways under their respective jurisdictions, may not deny reasonable access to a bus of a length of up to 45 feet between the highways specified in subdivision (a) of Section 35401.5 and points of loading and unloading for motor carriers of passengers as required by the federal Intermodal Surface Transportation Efficiency Act of 1991 (P.L. 102-240). (B) A bus operated by a public agency and on those highways specified in subparagraph (A) may be equipped with a folding device attached to the front of the bus that is designed and used exclusively for transporting bicycles. The device, including all bicycles transported thereon, may be mounted in a manner that does not materially affect efficiency or visibility of vehicle safety equipment, and may not extend more than 36 inches from the front body of the bus when fully deployed. The handlebars of a bicycle that is transported on a device described in this subparagraph may not extend more than 42 inches from the front of the bus. The total length of the bus, including the folding device or load, may not exceed 48.5 feet. A Route Review Committee, established under this subparagraph, shall review the routes where a public agency proposes to operate a 45-foot bus equipped with a front mounted bicycle rack. The Route Review Committee shall be comprised of one member from the public agency appointed by the general manager of the public agency; one member who is a traffic engineer and is employed and selected by the public agency that has jurisdiction over the largest proportional share of routes among all affected agencies; and one member appointed by the labor organization that is the exclusive representative of the bus drivers of the public agency. If there is no exclusive representative of the bus drivers, a bus driver member shall be chosen by a majority vote of the bus drivers employed by the agency. The members of the Route Review Committee shall be selected not more than 30 days after receipt of a public agency proposal to equip a 45-foot bus with a front mounted bicycle rack. The review shall include a field review of the proposed routes. The purpose of the Route Review Committee is to ensure the safe operation of a 45-foot bus that is equipped with a front mounted bicycle rack. The Route Review Committee, by a unanimous vote, shall make a determination of which routes are suitable for the safe operation of a 45-foot bus that is equipped with a front mounted bicycle rack. These determinations shall be consistent with the operating requirements specified in subparagraph (A). It is the intent of the Legislature that the field review required under this subparagraph include consultation with traffic engineers from affected public agencies that have jurisdiction over segments of the route or routes under review, to ensure coordination with all effected state and local public road agencies that may potentially be impacted due to the operation of a 45-foot bus with a front mounted bicycle rack. (11) (A) A house car of a length of up to 45 feet when operating on the National System of Interstate and Defense Highways or when using those portions of federal aid primary system highways that have been qualified by the United States Secretary of Transportation for that use, or when using routes appropriately identified by the Department of Transportation or local authorities, with respect to highways under their respective jurisdictions. (B) A house car described in subparagraph (A) may be operated on a highway that provides reasonable access to facilities for purposes limited to fuel, food, and lodging when that access is consistent with the safe operation of the vehicle and when the facility is within one road mile of identified points of ingress and egress to or from highways specified in subparagraph (A) for use by that vehicle. (C) As used in this paragraph and paragraph (10), "reasonable access" means access substantially similar to that authorized for combinations of vehicles pursuant to subdivision (c) of Section 35401.5. (D) Any access route established by a local authority pursuant to subdivision (d) of Section 35401.5 is open for access by a house car of a length of up to 45 feet. In addition, local authorities may establish a process whereby access to services by house cars of a length of up to 45 feet may be applied for upon a route not previously established as an access route. The denial of a request for access to services shall be only on the basis of safety and an engineering analysis of the proposed access route. In lieu of processing an access application, local authorities, with respect to highways under their jurisdiction, may provide signing, mapping, or a listing of highways, as necessary, to indicate the use of these specific routes by a house car of a length of up to 45 feet. (c) The Legislature, by increasing the maximum permissible kingpin to rearmost axle distance to 40 feet effective January 1, 1987, as provided in paragraph (4) of subdivision (b), does not intend this action to be considered a precedent for any future increases in truck size and length limitations. (d) Any transit bus equipped with a folding device installed on or after January 1, 1999, that is permitted under subparagraph (B) of paragraph (3) of subdivision (b) or under paragraph (9) of subdivision (b) shall be additionally equipped with any of the following: (1) An indicator light that is visible to the driver and is activated whenever the folding device is in an extended position. (2) Any other device or mechanism that provides notice to the driver that the folding device is in an extended position. (3) A mechanism that causes the folding device to retract automatically from an extended position. (e) (1) A person may not improperly or unsafely mount a bicycle on a device described in subparagraph (B) of paragraph (3) of subdivision (b), or in paragraph (9) or (10) of subdivision (b). (2) Notwithstanding subdivision (a) of Section 23114 or subdivision (a) of Section 24002 or any other provision of law, when a bicycle is improperly or unsafely loaded by a passenger onto a transit bus, the passenger, and not the driver, is liable for any violation of this code that is attributable to the improper or unlawful loading of the bicycle. 35400.5. Subdivision (a) of Section 35400 does not apply to a motortruck used solely as a cotton module mover and which does not exceed 48 feet in length. 35400.7. (a) Notwithstanding Section 35400, the Alameda-Contra Costa Transit District created pursuant to Part 1 (commencing with Section 24501) of Division 10 of the Public Utilities Code may install a folding device attached to the front of a bus that is designed and used exclusively for transporting bicycles if the following conditions are met: (1) The device does not extend more than 40 inches from the front body of the bus when fully deployed. (2) The device, including all bicycles transported thereon, is mounted in a manner that does not materially affect efficiency or visibility of vehicle safety equipment.

(a) Except as provided in subdivisions (b), (c), and (d), a combination of vehicles coupled together, including attachments, may not exceed a total length of 65 feet. (b) (1) A combination of vehicles coupled together, including attachments, that consists of a truck tractor, a semitrailer, and a semitrailer or trailer, may not exceed a total length of 75 feet, if the length of neither the semitrailers nor the trailer in the combination of vehicles exceeds 28 feet 6 inches. (2) A B-train assembly is excluded from the measurement of semitrailer length when used between the first and second semitrailers of a truck tractor-semitrailer-semitrailer combination of vehicles. However, if there is no second semitrailer mounted to the B-train assembly, it shall be included in the length measurement of the semitrailer to which it is attached. (c) (1) A tow truck in combination with a single disabled vehicle or a single abandoned vehicle that is authorized to travel on the highways by this chapter is exempt from subdivision (a) when operating under a valid annual transportation permit. (2) A tow truck, in combination with a disabled or abandoned combination of vehicles that are authorized to travel on the highways by this chapter, is exempt from subdivision (a) when operating under a valid annual transportation permit and within a 100-mile radius of the location specified in the permit. (3) A tow truck may exceed the 100-mile radius restriction imposed under paragraph (2) if a single trip permit is obtained from the Department of Transportation. (d) A city or county may, by ordinance, prohibit a combination of vehicles of a total length in excess of 60 feet upon highways under its respective jurisdiction. The ordinance may not be effective until appropriate signs are erected indicating either the streets affected by the ordinance or the streets not affected, as the local authority determines will best serve to give notice of the ordinance. (e) A city or county, upon a determination that a highway or portion of highway under its jurisdiction cannot, in consideration of public safety, sustain the operation of trailers or semitrailers of the maximum kingpin to rearmost axle distances permitted under Section 35400, may, by ordinance, establish lesser distances consistent with the maximum distances that the highway or highway portion can sustain, except that a city or county may not restrict the kingpin to rearmost axle measurement to less than 38 feet on those highways or highway portions. A city or county considering the adoption of an ordinance shall consider, but not be limited to, consideration of, all of the following: (1) A comparison of the operating characteristics of the vehicles to be limited as compared to operating characteristics of other vehicles regulated by this code. (2) Actual traffic volume. (3) Frequency of accidents. (4) Any other relevant data. In addition, the city or county may appoint an advisory committee consisting of local representatives of those interests that are likely to be affected and shall consider the recommendations of the advisory committee in adopting the ordinance. The ordinance may not be effective until appropriate signs are erected indicating the highways or highway portions affected by the ordinance. This subdivision shall only become operative upon the adoption of an enabling ordinance by a city or county. (f) Whenever, in the judgment of the Department of Transportation, a state highway cannot, in consideration of public safety, sustain the operation of trailers or semitrailers of the maximum kingpin to rearmost axle distances permitted under Section 35400, the director, in consultation with the Department of the California Highway Patrol, shall compile data on total traffic volume, frequency of use by vehicles covered by this subdivision, accidents involving these vehicles, and other relevant data to assess whether these vehicles are a threat to public safety and should be excluded from the highway or highway segment. The study, containing the conclusions and recommendations of the director, shall be submitted to the Secretary of the Business, Transportation and Housing Agency. Unless otherwise notified by the secretary, the director shall hold public hearings in accordance with the procedures set forth in Article 3 (commencing with Section 35650) of Chapter 5 for the purpose of determining the maximum kingpin to rear axle length, which shall be not less than 38 feet, that the highway or highway segment can sustain without unreasonable threat to the safety of the public. Upon the basis of the findings, the Director of Transportation shall declare in writing the maximum kingpin to rear axle lengths which can be maintained with safety upon the highway. Following the declaration of maximum lengths as provided by this subdivision, the Department of Transportation shall erect suitable signs at each end of the affected portion of the highway and at any other points that the Department of Transportation determines to be necessary to give adequate notice of the length limits. The Department of Transportation, in consultation with the Department of the California Highway Patrol, shall compile traffic volume, geometric, and other relevant data, to assess the maximum kingpin to rearmost axle distance of vehicle combinations appropriate for those state highways or portion of highways, affected by this section, that cannot safely accommodate trailers or semitrailers of the maximum kingpin to rearmost axle distances permitted under Section 35400. The department shall erect suitable signs appropriately restricting truck travel on those highways, or portions of highways. (g) This section shall become operative on January 1, 2010. 35401.1. A combination of vehicles operated pursuant to Section 35400 or 35401 with a kingpin to rearmost axle measurement of greater than 38 feet but not more than 40 feet may be operated on those highways under the jurisdiction of local authorities only where it is deemed to be safe by the owner of the vehicle or the person operating the vehicle and where its operation is not specifically prohibited by local ordinance pursuant to subdivision (d) of Section 35401. 35401.3. (a) Notwithstanding subdivisions (a) and (b) of Section 35401, a combination of vehicles designed and used to transport motor vehicles, camper units, or boats, which consists of a motortruck and stinger-steered semitrailer, shall be allowed a length of up to 70 feet if the kingpin is at least 3 feet behind the rear drive axle of the motortruck. This combination shall not be subject to subdivision (a) of Section 35411, but the load upon the rear vehicle of the combination shall not extend more than 6 feet 6 inches beyond the allowable length of the vehicle. (b) A combination of vehicles designed and used to transport motor vehicles, camper units, or boats, which consists of a motortruck and stinger-steered semitrailer, shall be allowed a length of up to 75 feet if all of the following conditions are maintained: (1) The distance from the steering axle to the rear drive axle of the motortruck does not exceed 24 feet. (2) The kingpin is at least 5 feet behind the rear drive axle of the motortruck. (3) The distance from the kingpin to the rear axle of the semitrailer does not exceed 34 feet except that the distance from the kingpin to the rear axle of a triple axle semitrailer does not exceed 36 feet. This combination shall not be subject to subdivision (a) of Section 35411, but the load upon the rear vehicle of the combination shall not extend more than 6 feet 6 inches beyond the allowable length of the vehicle. 35401.5. (a) A combination of vehicles consisting of a truck tractor and semitrailer, or of a truck tractor, semitrailer, and trailer, is not subject to the limitations of Sections 35400 and 35401, when operating on the National System of Interstate and Defense Highways or when using those portions of federal-aid primary system highways that have been qualified by the United States Secretary of Transportation for that use, or when using routes appropriately identified by the Department of Transportation or local authorities as provided in subdivision (c) or (d), if all of the following conditions are met: (1) The length of the semitrailer in exclusive combination with a truck tractor does not exceed 48 feet. A semitrailer not more than 53 feet in length shall satisfy this requirement when configured with two or more rear axles, the rearmost of which is located 40 feet or less from the kingpin or when configured with a single axle which is located 38 feet or less from the kingpin. For purposes of this paragraph, a motortruck used in combination with a semitrailer, when that combination of vehicles is engaged solely in the transportation of motor vehicles, camper units, or boats, is considered to be a truck tractor. (2) Neither the length of the semitrailer nor the length of the trailer when simultaneously in combination with a truck tractor exceeds 28 feet 6 inches. (b) Subdivisions (b), (d), and (e) of Section 35402 do not apply to combinations of vehicles operated subject to the exemptions provided by this section. (c) Combinations of vehicles operated pursuant to subdivision (a) may also use highways not specified in subdivision (a) which provide reasonable access to terminals and facilities for purposes limited to fuel, food, lodging, and repair when that access is consistent with the safe operation of the combinations of vehicles and when the facility is within one road mile of identified points of ingress and egress to or from highways specified in subdivision (a) for use by those combinations of vehicles. (d) The Department of Transportation or local authorities may establish a process whereby access to terminals or services may be applied for upon a route not previously established as an access route. The denial of a request for access to terminals and services shall be only on the basis of safety and an engineering analysis of the proposed access route. If a written request for access has been properly submitted and has not been acted upon within 90 days of receipt by the department or the appropriate local agency, the access shall be deemed automatically approved. Thereafter, the route shall be deemed open for access by all other vehicles of the same type regardless of ownership. In lieu of processing an access application, the Department of Transportation or local authorities with respect to highways under their respective jurisdictions may provide signing, mapping, or a listing of highways as necessary to indicate the use of specific routes as terminal access routes. For purposes of this subdivision, "terminal" means either of the following: (1) A facility where freight originates, terminates, or is handled in the transportation process. (2) A facility where a motor carrier maintains operating facilities. (e) Nothing in subdivision (c) or (d) authorizes state or local agencies to require permits of terminal operators or to charge terminal operators fees for the purpose of attaining access for vehicles described in this section. (f) Notwithstanding subdivision (d), the limitations of access specified in that subdivision do not apply to licensed carriers of household goods when directly enroute to or from a point of loading or unloading of household goods, if travel on highways other than those specified in subdivision (a) is necessary and incidental to the shipment of the household goods. (g) (1) Notwithstanding Sections 35400 and 35401, the Department of Transportation or local authorities, with regard to highways under their respective jurisdictions, may, upon application, issue a special permit authorizing the applicant to operate a combination of vehicles consisting of a truck tractor semitrailer combination operated pursuant to subdivision (a) with a kingpin to rearmost axle measurement limit of not more than 46 feet on trailers used exclusively or primarily in connection with motorsports. As used in this paragraph, "motorsports" means any event, and all activities leading up to that event, including, but not limited to, administration, testing, practice, promotion, and merchandising, that is sanctioned under the auspices of the member organizations of the Automobile Competition Committee for the United States. (2) A local authority, as a condition of issuing a special permit under this subdivision, may establish reasonable controls on the allowable hours of operation of those semitrailers that are authorized to operate under this subdivision. (h) The Legislature finds and declares both of the following: (1) In authorizing the use of 53-foot semitrailers, it is the intent of the Legislature to conform with Section 2311(b) of Title 49 of the United States Code by permitting the continued use of semitrailers of the dimensions as those that were in actual and legal use on December 1, 1982, and does not intend this action to be a precedent for future increases in the parameters of any of those vehicles that would adversely affect the turning maneuverability of vehicle combinations. (2) In authorizing the department to issue special transportation permits for motorsports, it is the intent of the Legislature to conform with Section 31111(b)(1)(E) of Title 49 of the United States Code. It is also the intent of the Legislature that this action not be a precedent for future increases in the distance from the kingpin to the rearmost axle of semitrailers that would adversely affect the turning maneuverability of vehicle combinations. 35401.7. (a) The limitations of access specified in subdivision (d) of Section 35401.5 do not apply to licensed carriers of livestock when those carriers are directly en route to or from a point of loading or unloading of livestock on those portions of State Highway Route 101 located in the Counties of Del Norte, Humboldt, and Mendocino from its junction with State Highway Route 1 near Leggett north to the Oregon border, if the travel is necessary and incidental to the shipment of the livestock. (b) The exemption allowed under this section does not apply unless all of the following conditions are met: (1) The length of the truck tractor, in combination with the semitrailer used to transport the livestock, does not exceed a total of 70 feet. (2) The distance from the kingpin to the rearmost axle of the semitrailer does not exceed 43 feet. (3) The length of the semitrailer does not exceed a total of 48 feet. (c) The exemption allowed under this section does not apply to travel conducted on the day prior to, or on the day of, any federally recognized holiday. (d) The Department of the California Highway Patrol, in consultation with the Department of Transportation and in accordance with recommendations from the Department of the California Highway Patrol's study issued on March 20, 2006, of the effect of the statutory exemption, shall continue the comprehensive study of the effect that the exemption provided by this section has on the public safety during the extended effective period of the exemption, and make recommendations on future exemptions, including the creation of a permitting system for cattle truck and trailer combinations meeting applicable provisions of the federal Surface Transportation Assistance Act of 1982 (Public Law 97-424), and appropriate safety improvements. Notwithstanding Section 7550.5 of the Government Code, the Department of the California Highway Patrol shall report the findings of this additional study and recommendations to the Governor and the Legislature on or before January 1, 2011. (e) This section shall remain in effect only until January 1, 2012, and as of that date is repealed, unless a later enacted statute, that is enacted before January 1, 2012, deletes or extends that date. (f) (1) If prior to January 1, 2012, the Director of Transportation determines that the only adjustment to State Highway Route 101 possible to accommodate the truck sizes allowed to travel on portions of State Highway Route 101, pursuant to subdivisions (a) and (b) is the removal of any tree that has a diameter of 42 inches or greater, measured outside the bark, at 12 inches above ground on the side adjacent to the highest ground level, the director shall notify the Secretary of State of that determination. (2) If prior to January 1, 2012, the Director of Transportation determines that safety improvements to the portion of State Highway Route 101 described in subdivision (a) have resulted in the reclassification of the entire segment as a terminal access route pursuant to subdivision (d) of Section 35401.5, the director shall notify the Secretary of State of that determination. (3) The notice required under paragraph (1) or (2) shall state that it is being made pursuant to this section. (4) This section is repealed on the date the Secretary of State receives either of the notices described in this subdivision. 35402. (a) Any extension or device, including any adjustable axle added to the front or rear of a vehicle, used to increase the carrying capacity of a vehicle shall be included in measuring the length of a vehicle, except that a drawbar shall not be included in measuring the length of a vehicle but shall be included in measuring the overall length of a combination of vehicles. (b) Notwithstanding subdivision (a), extensions of not more than 18 inches in length on each end of a vehicle or combination of vehicles used exclusively to transport vehicles shall not be included in measuring the length of a vehicle or combination of vehicles when the vehicles are loaded. (c) Notwithstanding subdivision (a), an extension of not more than 18 inches in length on the last trailer in a combination of vehicles transporting loads shall not be included in measuring the length of a vehicle or combination of vehicles when the vehicles are loaded. Additionally, an extension of not more than 18 inches in length on the front of the first trailer in a combination of vehicles transporting loads shall not be included in measuring the length of a vehicle or combination of vehicles when the vehicles are loaded and on highways, other than those highways designated by the United States Department of Transportation as national network routes. (d) Notwithstanding subdivision (a), any extension or device which is not used to carry any load and which does not exceed three feet in length, added to the rear of a vehicle, and is used exclusively for pushing the vehicle or a combination of vehicles, which vehicle or combination of vehicles is designed and used exclusively to transport earth, sand, gravel, and similar materials, shall be included in measuring the length of the vehicle but shall not be included in measuring the overall length of the combination of vehicles. (e) Notwithstanding subdivision (a), a truck semitrailer combination, but not a truck tractor and semitrailer combination, may use a sliding fifth wheel, or a truck tractor, semitrailer, trailer, and a truck-trailer combination may use a sliding drawbar, to extend the length of the combination by not more than 2 feet 6 inches while traveling 35 miles per hour or less on any highway, except a freeway. These provisions shall apply, however, to freeway onramps and offramps and freeway connectors. The sliding fifth wheel or drawbar when extended shall not be included in measuring the overall length of the combination of vehicles if the pivot point of the semitrailer connection is more than two feet to the rear of the center of the rearmost axle of the motortruck or if the distance from the pivot point to the center of the rearmost axle of the semitrailer does not exceed 34 feet. Combinations of vehicles permitted by this subdivision shall be in compliance with the weight limits provided in Article 1 (commencing with Section 35550) of Chapter 5 whenever any drawbar or sliding fifth wheel is extended, contracted, or in any intermediate position as provided for by this subdivision. 35403. Safety devices which are required to be mounted upon a vehicle pursuant to provisions of this code, may extend beyond the permissible length of a vehicle, or a combination of vehicles, to a distance not exceeding 10 inches. 35404. Any county having a population in excess of 4,000,000 and having within its limits a natural island with an area in excess of 20,000 acres may, by ordinance, prohibit the use of any highway or lane, hereafter established in unincorporated area thereon, (1) by any vehicle exceeding an overall length of 170 inches and an overall width of 65 inches, or (2) by any such vehicle and all vehicles driven by internal combustion engines. Notwithstanding the provisions of Section 906 of the Streets and Highways Code, no such ordinance shall be enacted unless the board of supervisors shall have theretofore adopted, by a four-fifths vote, a resolution determining that the public convenience and necessity require that such highway or lane have a width of 35 feet or less and a roadway width of 22 feet or less. Any ordinance enacted pursuant to this section shall be subject to Sections 35718 to 35720, inclusive, of this code and shall not apply to authorized emergency vehicles. 35406.
