Whenever any resolution of this city designates and describes any street or portion thereof as a street the use of which is permitted by any vehicle exceeding a maximum gross weight limit of five tons, the city traffic engineer is authorized to designate such street or streets by appropriate signs as "Truck Routes" for the movement of vehicles exceeding a maximum gross weight limit of five tons. Established "Truck Routes" will be identified separately from "State and Local Terminal Access Routes." "Terminal Access Routes" will be considered "Truck Routes" but "Truck Routes" are not "Terminal Access Routes" for purposes of over-length vehicles. "Truck Routes," "State Terminal Access Routes," and "Local Terminal Access Routes" will be identified on the approved city truck route map. (Ord. 2431 NCS § 1 (part), 2012.)
