2021 Louisiana Laws|Revised Statutes|Title 32 - Motor Vehicles and Traffic Regulation|§235. Uniform highway marking system

RS 235 - Uniform highway marking system A.(1) The department shall adopt a manual and specifications for a uniform system of traffic control devices consistent with the provisions of this Chapter for use upon highways within this state. Such uniform system shall correlate with and so far as possible conform to the system then current as approved by the United States Department of Transportation, Federal Highway Administration, Manual on Uniform Traffic Control Devices (MUTCD), except that the department shall develop a supplement to the manual with all symbol-based or bilingual signs that display terms in both English and Louisiana French, subject to approval by the United States Department of Transportation, Federal Highway Administration, which permits parish governing authorities to adopt such supplement, request that signs along state and federal highways within their boundaries be bilingual, and display terms in both English and Louisiana French. In developing the supplement, the department shall adhere to the following: (2) The department shall coordinate with the Council for the Development of French in Louisiana pursuant to R.S. 25:651 et seq., prior to application for approval from the United States Department of Transportation, Federal Highway Administration. (3) The supplement shall provide a process by which a parish governing authority may formally adopt the supplement. In the event the United States Department of Transportation, Federal Highway Administration does not approve the bilingual supplement, it shall be returned to the governing authority of the parish which requested approval of a bilingual supplement. The parish governing authority may only proceed with local adoption of the supplement as it was submitted to the United States Department of Transportation, Federal Highway Administration but shall not erect any bilingual sign on any state or federal highway within the parish; signs installed on parish roads shall be at the expense of the parish. (4) The department may deviate from the system and erect advisory signs only to post advisory weight limits on state bridges where a state bridge is scheduled for replacement or strengthening within three years from the date of approval by the chief engineer of the department's weight rating evaluation of any state bridge. In addition, the department may deviate from the criteria contained in said system for location of traffic signals to the extent that additional weighted consideration shall be given to pedestrian and vehicular traffic volumes associated with schools which are located on state highways. (5) The department shall require that any signage on public highways which indicates maximum or minimum speed limits in kilometers also indicate such speed limits in miles per hour. B. Local municipal and parish authorities in their respective jurisdictions shall place and maintain such traffic control devices upon highways under their jurisdiction as they may deem necessary to indicate and to carry out the provisions of this Chapter, regulations of the department and commissioner adopted pursuant hereto, and local traffic ordinances adopted pursuant to the authority granted by R.S. 32:41 and R.S. 32:42. All such traffic control devices hereafter erected shall conform to the department's manual or specifications. If any such device hereafter erected by a political subdivision of this state fails to conform to the manual or specifications, payment of any funds allocated to that political subdivision shall be withheld by the department until the standards established by the department are complied with. C. No local municipal or parish authority shall place or maintain any traffic control device upon any state maintained highway without having first obtained the written approval of the department. D. Wherever any highway crosses the boundaries of and enters into the state of Louisiana, the department may erect appropriate signs giving notice of the maximum speed limits authorized by law for each type of vehicle upon the highways of this state. E. Proof that any state, parochial or municipal authority was at the time of any incident complained of in compliance with the provisions of the department's traffic control devices manual shall be prima facie evidence of discharge by such authority of its obligations to the motoring public.
