I. The commissioner of transportation and, subject to his approval, selectmen of any town or board of mayor and aldermen or group having similar powers in any city, having control of any highway may order such marking of ways, by painted lines, as is deemed necessary to the safe and efficient use of any such way. In ordering or approving such marking the commissioner of transportation insofar as is practicable shall conform to nationally accepted standards and any marking of the way by painted lines shall prima facie be deemed to be approved or ordered by the commissioner of transportation.

      (a) In an emergency; or
