Prior to the adoption of any municipal or county ordinance, resolution, or regulation, which places any impact on roadways in an adjoining municipality or county, the governing board or body of the municipality or county shall provide appropriate notice to the adjoining municipality or county.
Notwithstanding any other provision of this section to the contrary, any municipal or county ordinance, resolution, or regulation which places any impact on a State roadway shall require the approval of the commissioner.
Where the commissioner's approval is required, a certified copy of the adopted ordinance, resolution, or regulation shall be transmitted by the clerk of the municipality or county, as applicable, to the commissioner within 30 days of adoption, together with: a copy of the municipal or county engineer's certification, a statement of the reasons for the municipal or county engineer's decision, detailed information as to the location of streets, intersections, and signs affected by the ordinance, resolution, or regulation, and traffic count, crash, and speed sampling data, when appropriate. The commissioner may invalidate the provisions of the ordinance, resolution, or regulation if the commissioner finds that the provisions of the ordinance, resolution, or regulation are inconsistent with the Manual on Uniform Traffic Control Devices for Streets and Highways, inconsistent with accepted engineering standards, are not based on the results of an accurate traffic and engineering survey, or place an undue traffic burden or impact on the State highway system, or affect the flow of traffic on the State highway system.
The provisions of the ordinance, resolution, or regulation shall be consistent with the Manual on Uniform Traffic Control Devices for Streets and Highways, consistent with accepted engineering standards, based on the results of an accurate traffic and engineering survey, and not place an undue traffic burden or impact on streets in an adjoining municipality or negatively affect the flow of traffic on the State highway system.
Nothing in this subsection shall allow municipalities to designate any intersection with any highway under State or county jurisdiction as a stop or yield intersection or counties to designate any intersection with any highway under State or municipal jurisdiction as a stop or yield intersection.
