Summary

This report presents the findings of the Summer 2008 observational survey of safety belt and motorcycle helmet use in Virginia, conducted by the Virginia Transportation Research Council at the request of the Virginia Department of Motor Vehicles. The study aims to track the effectiveness of statewide programs designed to increase restraint usage and to provide data for reporting to the National Highway Traffic Safety Administration (NHTSA). The research is motivated by the established 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 guidelines for probability-based sampling and direct observation. The survey covered 140 sites selected to represent urban and rural populations proportionally, excluding jurisdictions comprising less than 15 percent of the state’s population. Data collectors observed traffic at these sites for one hour each, recording shoulder belt use for drivers and right-front passengers in passenger motor vehicles (cars, trucks, vans, minivans, and SUVs) and helmet use for motorcycle drivers and passengers. Observations were weighted by the number of traffic lanes to estimate statewide usage rates. The survey period ran from June 2 to the third Sunday in June 2008, with data collected during daylight hours across all days of the week. The results indicated that Virginia’s safety belt use rate for passenger motor vehicle occupants was 78.7 percent in Summer 2008, based on 21,763 weighted observations. This represents a slight decrease from the 79.9 percent rate recorded in 2007. The relative error for this estimate was 0.48 percent. Motorcycle helmet use remained exceptionally high at 97.8 percent, based on 204 observations, with a relative error of 0.49 percent. Historical data from 1992 through 2008 showed that safety belt use rates fluctuated between a low of 67.1 percent in 1997 and a high of 80.4 percent in 2005. Motorcycle helmet compliance was consistently near 100 percent across all surveyed years. The authors conclude that the slight decline in safety belt use from 2007 to 2008 may be attributable to differences in travel patterns or other extraneous variables rather than a significant change in driver behavior. The report emphasizes that variations in annual rates should be interpreted with caution due to methodological changes implemented prior to 2003. The findings confirm that while motorcycle helmet compliance is nearly universal in Virginia, safety belt usage remains below the 85 percent and 90 percent targets established by federal initiatives in the late 1990s, highlighting the continued need for programmatic efforts to improve occupant protection.
