Summary

This study investigates the patterns of safety belt usage among drivers killed in fatal motor vehicle crashes in Virginia during fiscal year 1974. The research was motivated by the controversy surrounding mandatory seat belt legislation and the need to determine whether safety belt utilization serves as a safeguard against fatal injuries. Specifically, the study aimed to examine the representation of belt users among fatalities compared to the general driving population and to identify demographic and accident-related variables that distinguish users from nonusers. The methodology involved reviewing FR300 accident report forms and corresponding medical examiner’s reports for drivers killed in fatal crashes between July 1, 1973, and June 30, 1974. The study included 274 qualifying cases where safety belts were installed, usage could be determined, and death was directly attributed to the accident. These cases were compared against safety belt usage rates in the general driving populations of Virginia, North Carolina, and Ohio, as well as against drivers involved in fatal collisions who survived. Additionally, the 274 fatalities were analyzed across 26 accident-related and demographic variables, including driver sex, age, vehicle age, time of day, road conditions, and driver behavior. The results indicated that only 12.4% of the fatally injured drivers were wearing safety belts, while 87.6% were nonusers. This usage rate was statistically significantly lower than the estimated 24.0% usage rate among the general driving population in Virginia, as well as estimates from North Carolina and Ohio. Furthermore, safety belt users were significantly underrepresented among fatalities compared to drivers involved in fatal collisions who survived. Significant differences were found between users and nonusers regarding several variables: a greater proportion of nonusers were male, violated traffic laws, or had been drinking at the time of the accident. Nonusers were also more likely to be killed on weekends, in vehicles six years old or older, on defective roads, and between 6:00 p.m. and 11:59 p.m. The study concludes that safety belt users were underrepresented among Virginia fatalities, suggesting that safety belt utilization is a considerable safeguard against fatal injuries. The findings support the hypothesis that increased belt usage contributes to a decrease in fatalities, providing empirical evidence relevant to the debate on mandatory seat belt legislation. The data reinforces previous studies indicating that nonusers are overrepresented in fatal crash statistics, highlighting the protective effectiveness of safety restraints.

Key finding

Safety belt users were significantly underrepresented among fatally injured drivers in Virginia during fiscal year 1974, with a usage rate of 12.4% compared to 24.0% in the general driving population.
