Whenever special pedestrian-control signals exhibiting the words "Walk" or "Don't Walk" or the illuminated signals of a walking person or an upraised palm are in place, these signals shall indicate as follows:
   (A)   Walk or walking person symbol. Pedestrians facing this signal may proceed across the roadway in the direction of the signal, and shall be given the right-of-way by the drivers of all vehicles.
   (B)   Don't walk or upraised palm signal.  No pedestrian shall start to cross the roadway in the direction of this signal, but any pedestrian who has partly completed his crossing on the "Walk" signal or walking person symbol shall proceed to a sidewalk or safety island while the "Don't Walk" signal or upraised palm signal is illuminated, steady, or flashing.
