Where traffic-control signals are not in place or in operation, the driver of a vehicle shall yield the right of way, slowing down or stopping if need be, to a pedestrian crossing the roadway or street within any marked crosswalk or within any unmarked crosswalk.
Whenever stop signals or flashing red signals are in place at an intersection or a marked crosswalk between intersections the pedestrian shall have the right of way over drivers of vehicles; and at such marked places drivers of vehicles shall stop before entering the nearest crosswalk and any pedestrian within or entering the crosswalk at either edge of the roadway shall have the right of way over any vehicle so stopped.
