Summary

This report presents the findings of the Summer 2006 statewide survey on safety belt and motorcycle helmet use in Virginia, conducted by the Virginia Transportation Research Council (VTRC) for the Virginia Department of Motor Vehicles. The study aims to track the effectiveness of programmatic efforts to increase restraint usage and to provide data required by the National Highway Traffic Safety Administration (NHTSA) for federal incentive grant allocations. The research is motivated by the proven benefits of safety restraints, which reduce the risk of death for front-seat occupants by 45 percent and serious injury by 50 percent, while also lowering inpatient hospital care costs. The methodology adhered to NHTSA’s probability-based sampling guidelines, utilizing direct observational data collected at 140 sites across Virginia. These sites were stratified to reflect the state’s urban and rural population distribution, with 85 sites in metropolitan areas and 55 in rural areas. Data collectors observed traffic at randomly selected intersections during one-hour intervals throughout June 2006. The survey focused on drivers and right-front outboard passengers aged 16 and older in passenger motor vehicles, as well as motorcycle drivers and passengers. Observations were weighted by the number of traffic lanes to estimate statewide usage rates, and rigorous training protocols ensured inter-collector reliability. The results indicated a statewide safety belt use rate of 78.7 percent for passenger vehicle occupants, based on 26,714 weighted observations. This represents a 1.7 percent decrease from the summer 2005 rate of 80.4 percent, which had been the highest recorded since the adoption of the current protocol in 1992. Conversely, the motorcycle helmet use rate remained exceptionally high at 99.1 percent, based on 507 observations. Historical data from 1992 to 2005 showed safety belt use fluctuating between a low of 67.1 percent in 1997 and the 2005 peak. The relative error for the 2006 safety belt estimate was 1.27 percent, while the helmet use estimate had a relative error of 0.11 percent. The report concludes that while helmet compliance in Virginia is near universal, safety belt usage has plateaued and slightly declined from recent highs. The authors caution that annual variations in use rates may be influenced by extraneous variables, such as changes in travel patterns or economic factors like gas prices, rather than solely reflecting changes in driver behavior. The data confirms that Virginia’s survey methods meet federal criteria for accuracy and representativeness, supporting the state’s eligibility for federal safety incentive grants.
