Dept. of TransportationVirginia. Dept. of Motor VehiclesUS Transportation CollectionThe Virginia Transportation Research Council has been collecting safety belt use data in Virginia since 1974. In 1992, the National Highway Traffic Safety Administration (NHTSA) published the final guidelines for conducting surveys of belt and helmet use in the states. As of the 1992 survey, Virginia adopted the NHTSA protocol for its statewide survey. The results showed that Virginia's summer 2007 safety belt use rate was 79.9 percent and its motorcycle helmet use rate was 96.1 percent. In the 15 previous surveys, virtually all of the motorcycle drivers and passengers observed were using a helmet. For passenger car drivers and right front passengers observed from 1992 through 2007, use rates varied from a low of 67.1 percent in 1997 to a high of 80.4 percent in the summer of 2005. The summer 2007 use rate was 0.5 percent lower than the rate for summer 2005. It should be noted, however, that any differences between annual use rates might be attributable to differences in travel patterns or other extraneous variables, such as increases in gas prices and the resulting reduction in pleasure trips, rather than solely to changes in driver and occupant behavior
