Preferential lane markings (Repealed)

(a) When a lane is assigned full or part time to a particular class or classes of vehicles, the preferential lane markings shall be used. The marking is intended to convey that a restriction on the class or classes of vehicles permitted to use the lane exists, and it is supplemental to signs or signals conveying the specific restrictions. Signs or signals shall be used with the preferential lane markings. (b) The preferential lane markings for a high-occupancy vehicle lane shall be the elongated diamond detailed in the Standard Alphabets for Highway Signs and Pavement Markings. The diamond shall be formed by white lines at least 6 inches in width, shall be at least 2 1/2 feet in width and 12 feet long and shall be placed coincident with the longitudinal center of each restricted lane.
