The cause and nature of head injuries sustained by pedestrians.

For pedestrians struck by cars the following conclusions are made: children sustain less severe injuries than adults at high impact speeds and this is mainly due to their sustaining less servere head injuries; for both children and adults the head is the body area sustaining life-threatening or fatal injuries; life-threatening or fatal head injuries are often more caused by vehicle contact than road contact; and the windscreen frame is responsible for most of the life-threatening or fatal head injuries caused by vehicle contact.
