(1) The operator of a vehicle shall yield the right of way, slowing down or stopping, if need be to so yield to any pedestrian, but 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 impossible for the driver to yield.

(2) Whenever any vehicle slows or stops so as to yield to pedestrian traffic, the operator of any other vehicle approaching from the rear shall not overtake and pass such a vehicle which has slowed or stopped to yield to pedestrian traffic.

(3) Every pedestrian crossing at any point other than within a marked crosswalk or within an unmarked crosswalk at an intersection shall yield the right of way to all vehicles.

(4) Where a sidewalk is provided, pedestrians shall proceed upon such a sidewalk.
