It is never ideal for a pedestrian to be walking near a busy interstate. With all the cars and trucks whizzing by at high rates of speed, pedestrians are especially vulnerable on an interstate. Interstates are constructed to allow the rapid movement of motor vehicles; they are not meant to accommodate an abundance of pedestrian traffic. A pedestrian could easily be fatally injured if hit by a truck or car moving at highway speeds. And in fact, over 10 percent of fatal pedestrian accidents occur on interstates.
