Summary

This report presents the findings of a 1977 observational survey conducted by the Virginia Highway and Transportation Research Council to determine seat belt and shoulder strap usage among urban travelers in Virginia. The study was motivated by the discrepancy between the widespread availability of seat belts in new vehicles and their actual use by the motoring public, despite various safety campaigns and legislative efforts. The research aimed to provide empirical data on restraint usage rates across different demographics, vehicle types, and geographic regions within the state. The methodology involved observer-data collectors surveying motorists at signalized intersections in four major metropolitan areas: Western, Northern, Central, and Eastern Virginia. Over nine days in June 1977, observers recorded data from 4,118 vehicles containing 6,479 occupants. Observers approached vehicles in the curb lane, visually verifying whether drivers, right-front passengers (RFPs), and other passengers were using lap belts, lap-and-shoulder belts, or no restraints. Data collectors also recorded occupant sex, approximate age, and vehicle license numbers, which were later matched to model years ranging from pre-1963 to 1977. The survey covered three time periods throughout the day to ensure varied sampling. The results indicated extremely low seat belt usage overall. Only 16.3% of drivers, 9.8% of RFPs, and 3.4% of remaining passengers used any form of restraint. A strong association was found between driver and RFP behavior; when drivers did not use belts, 96.7% of RFPs also did not use them, whereas RFP usage rose to 54.6% when drivers used both lap and shoulder belts. Female drivers and RFPs exhibited higher usage rates than males. Usage peaked in 1972/1973 vehicles, which were equipped with continuous buzzers, and in 1975 models with interlock systems, before declining in newer 1976/1977 models. Geographically, Northern Virginia showed the highest usage rates, while Eastern Virginia had the lowest. Infant restraint use via approved child seats was recorded at 10.3%. The study concludes that seat belt usage among urban Virginia travelers in 1977 was minimal, with less than one in five drivers utilizing restraints. The findings highlight that driver behavior significantly influences passenger compliance and that specific vehicle features, such as buzzers and interlocks, correlated with higher usage rates. The data suggests that despite regulatory mandates for equipment installation, voluntary compliance remained low, with significant variations based on gender, vehicle age, and location. These results underscore the need for continued safety interventions and potentially stricter enforcement to improve restraint usage.
