No local authority may enact or enforce a law that applies only to motorcycles and the principal purpose of which is to restrict the access of motorcycles to any highway or portion of a highway under the jurisdiction of any such local authority for which state funds have been utilized for planning, design, construction or maintenance. Provided, however, that nothing contained herein shall be deemed to supersede the authority of any local authority to regulate traffic pursuant to the provisions of this title, or to regulate noise.
