SAFETY BELT EFFECTIVENESS IN PREVENTING DRIVER FATALITIES VERSUS A NUMBER OF VEHICULAR, ACCIDENT, ROADWAY, AND ENVIRONMENTAL FACTORS
Safety belt effectiveness in preventing fatalities to drivers is examined versus a number of factors by applying the double pair comparison method to appropriate subsets of the Fatal Accident Reporting System data. For each of 13 factors studied, safety belt effectivenesss (the % of fatally injured unbelted drivers who would not have been killed if they had been wearing safety belts) is estimated, as is an associated standard error of the estimate. The results, which are presented graphically, provide no evidence that safety belt effectiveness is systematically influenced by most of the factors investigated, including car mass and model year. The absence of any systematic relationship with car mass is in agreement with an earlier finding based on the pedestrian fatality exposure method; this agreement adds plausibility to the assumptions used for both the earlier and the present methods. Safety belt effectiveness is greater for single car crashes than for crases involving 2 cars, this difference being statistically significant p less than .02. The results suggest weakly that safety belt effectiveness is greater for 2-door than for 4-door cars, and is greater for striking cars than for struck cars. The differences probably reflect higher effectiveness in frontal (or rollover) crashes than in side impacts.
