The Commonwealth Transportation Board may develop a residential cut-through traffic policy and procedure for the control of residential cut-through traffic on designated secondary highways. For the purposes of this section, “residential cut-through traffic” means vehicular traffic passing through a residential area without stopping or without at least an origin or destination within the area. The provisions of this section shall not apply in (i) cities, (ii) any town that maintains its own system of streets, and (iii) any county that owns, operates, and maintains its own system of highways.
