Abstract
Hospital records of road accident victims, injuries and casualties, were compared with police records of road accidents during a monthly period. The seriousness of injuries was estimated and classified. Two criteria were used: according police guidelines and the length of time unfit for labour. It was found that a high percentage of accidents (49%), even those involving serious injuries, were unknown to the police. These were mainly in the category of pedestrians and cyclists, but also mainly in the accidents caused by skidding.
