Traffic controls for certain parking areas and commercial establishments

The Office of the State Traffic Administration, in cooperation and agreement with local traffic authorities, may, in any parking area for twenty or more vehicles or for any commercial establishment having an exit or entrance on or abutting or adjoining any state highway, establish traffic controls by signal or device, for access to and egress from and for traffic within such parking area or commercial establishment. The traffic authority of any city, town or borough may establish similar controls for parking areas for twenty or more vehicles or for any commercial establishment having an exit or entrance on or abutting or adjoining any highway under their jurisdiction. The owner or operator of any parking area or commercial establishment where such traffic controls have been established, pursuant to this section, shall erect and maintain the necessary uniform traffic control signals or devices, which shall conform to the specifications of the manual of uniform traffic control devices established under this chapter and as approved and revised by the Office of the State Traffic Administration, provided no traffic control signal or device shall be installed, operated or maintained until a permit for such installation, operation or maintenance has been procured from the Office of the State Traffic Administration.
