(a) The Board of Transportation, with reference to State highways, and local authorities, with reference to highways under their jurisdiction, are hereby authorized to erect or install, at intersections or other appropriate places, special pedestrian control signals exhibiting the words or symbols "WALK" or "DON'T WALK" as a part of a system of traffic-control signals or devices.
(b) Whenever special pedestrian-control signals are in place, such signals shall indicate as follows:
(1) WALK. - Pedestrians facing such signal may proceed across the highway in the direction of the signal and shall be given the right-of-way by the drivers of all vehicles.
(2) DON'T WALK. - No pedestrian shall start to cross the highway in the direction of such signal, but any pedestrian who has partially completed his crossing on the "WALK" signal shall proceed to a sidewalk or safety island while the "DON'T WALK" signal is showing.
(c) Where a system of traffic-control signals or devices does not include special pedestrian-control signals, pedestrians shall be subject to the vehicular traffic-control signals or devices as they apply to pedestrian traffic.
(d) At places without traffic-control signals or devices, pedestrians shall be accorded the privileges and shall be subject to the restrictions stated in Part 11 of this Article.
