Bicyclists | 2007

Less than two percent of motor vehicle crash deaths are bicyclists. The most serious injuries among a majority of those killed are to the head, highlighting the importance of wearing a bicycle helmet. Helmet use has been estimated to reduce head injury risk by 85 percent. Thompson, R.S.; Rivara, F.P.; and Thompson, D.C. 1989. A case-control study of the effectiveness of bicycle safety helmets. New England Journal of Medicine 320:1361-67. Twenty-one states and the District of Columbia have helmet laws applying to young bicyclists; none of these laws applies to all riders. Local ordinances in a few states require some or all bicyclists to wear helmets. A nationwide telephone survey estimated that state helmet use laws increase by 18 percent the probability that a rider will wear a helmet. Rodgers, G.B. 2002. Effects of state helmet laws on bicycle helmet use by children and adolescents. Injury Prevention 8:42-46. Helmets are important for riders of all ages, especially because 85 percent of bicycle deaths are persons 16 and older.

The following facts are based on analysis of data from the U.S. Department of Transportation's Fatality Analysis Reporting System (FARS).
