In 2010, the 4,502 motorcyclists (operators and passengers) killed in motorcycle crashes made up 14% of all road traffic deaths, yet motorcycles accounted for <1% of all vehicle miles traveled.1-2 Helmet use consistently has been shown to reduce motorcycle crash–related injuries and deaths, and the most effective strategy to increase helmet use is enactment of universal helmet laws.3 Universal helmet laws require all motorcyclists to wear helmets whenever they ride. To examine the association between states' motorcycle helmet laws and helmet use or nonuse among fatally injured motorcyclists, CDC analyzed 2008–2010 National Highway Traffic Safety Administration (NHTSA) data from the Fatality Analysis Reporting System (FARS), a census of fatal traffic crashes in the United States.1 Additionally, economic cost data from NHTSA were obtained to compare the costs saved as a result of helmet use, by type of state motorcycle helmet law. The findings indicated that, on average, 12% of fatally injured motorcyclists were not wearing helmets in states with universal helmet laws, compared with 64% in partial helmet law states (laws that only required specific groups, usually young riders, to wear helmets) and 79% in states without a helmet law. Additionally, in 2010, economic costs saved from helmet use by society in states with a universal helmet law were, on average, $725 per registered motorcycle, nearly four times greater than in states without such a law ($198).
