Abstract
Studies in Sweden has raised doubts as to the accuracy of road accident statistics in relation to serious and slight injuries. To explore the reliability of British statistics an analysis has been made of a sample of 1200 patients injured in road accidents and attending hospital. Less than one quarter of those known to the hospital appeared in the official statistics. It is concluded that similar comparisons of hospital and police information be made elsewhere to confirm whether this sample is representative of the national rate of notification.
