§ 1151. Pedestrians' right of way in crosswalks. (a) When
traffic-control signals are not in place or not in operation the driver
of a vehicle shall yield the right of way, slowing down or stopping if
need be to so yield, to a pedestrian crossing the roadway within a
crosswalk on the roadway upon which the vehicle is traveling, except
that any pedestrian crossing a roadway at a point where a pedestrian
tunnel or overpass has been provided shall yield the right of way to all
vehicles.

(b) No pedestrian shall suddenly leave a curb or other place of safety
and walk or run into the path of a vehicle which is so close that it is
impractical for the driver to yield.

(c) Whenever any vehicle is stopped at a marked crosswalk or at any
unmarked crosswalk at an intersection to permit a pedestrian to cross
the roadway, the driver of any other vehicle approaching from the rear
shall not overtake and pass such stopped vehicle.
