Truck drivers were more seriously injured than car drivers; the odds ratio was 1.87 (95% confidence interval: 1.33, 2.63) for having an injury severity score of 9 or more. Limb and abdominal lesions were more frequent and more serious among truck drivers. The lack of seatbelt wearing by truck drivers was one of the factors that explained the particular severity of their injuries; the odds ratio, adjusted for seatbelt wearing, for truck drivers to be seriously injured was 1.04 (95% confidence interval: 0.73, 1.47) compared with car drivers. When all of the severity factors were taken into account, the risk was even lower, but not significantly so. accidents; injury severity score; risk factors; seat belts Abbreviations: AIS, Abbreviated Injury Scale; ISS, injury severity score.
