A pedestrian who gets hurt on a highway is among the most likely to die from his or her injuries. If he or she survives, injuries can be devastating. Highways are not meant for pedestrians, so it may call into question the reason the person was on the highway to begin with. Pedestrians are required by law to use an appropriate level of care when they're in a dangerous situation; if the pedestrian's own conduct results in injuries or death, then he or she may have his or her claim reduced or eliminated completely.
There are some questions that have to be answered after a pedestrian accident on a highway. First, why was the pedestrian on the highway? Was he or she simply walking across the highway? Is the highway between two major businesses, or is it fenced off to prevent people from entering?
