If there are no traffic-control signals to direct a pedestrian about when to walk, the driver of a vehicle must yield the right of way to a pedestrian in a crosswalk by slowing down or stopping. If a motorist fails to yield the right of way to a pedestrian as required by law, and strikes the pedestrian, the driver is responsible for the injuries suffered by the pedestrian. However, it is important to note that a pedestrian cannot 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 to the pedestrian.
