A sample of 1603 car occupants was analysed to report on the frequency, severity and causation of head injuries in car accidents. The majority of the occupants were restrained in the front seats. The importance of head injuries and the type of blows causing head injuries in general was examined. It was found that 65% of fatalities had a head injury of AIS 3 to 6, and in the majority of cases brain injuries occur without skull fracture regardless of survival. It was also found that 64% of head injuries scored above AIS 2 were caused by objects outside the vehicle. Facial injuries were also examined and eye injuries were found to be rare. The steering wheel rim and hub were found to be the most common cause of non-surface facial injuries to drivers, whereas surface facial injuries were attributable to a variety of causes.
