Traffic-related injuries among the elderly are a growing concern in most developed and many developing countries. To better understand injuries sustained by the elderly in the traffic environment, hospitalizations for traffic-related injuries among those aged 64 and over in California in 1994 were examined to determine incidence and characterize injuries. Both injury incidence and injury severity increased as age increased over 64. Males were more likely to be injured as drivers of motor vehicles, but females were more likely to be injured as passengers. Fractures and internal injuries represented 72.3% of all primary diagnoses, and total hospital charges exceeded $140 million. Efforts to reduce traffic-related injuries in the elderly and to reduce injury severity will be increasingly important as the elderly comprise a larger proportion of the population.
