SAFETY-BELT EFFECTIVENESS: THE INFLUENCE OF CRASH SEVERITY AND SELECTIVE RECRUITEMENT

It can be conluded from this study that (1) empirical data from two sources confirm that driver safety belt effectiveness declines as car crash severities increases; (2) the probability that a driver is belted declines as crash severities increases - the drivers who would benefit most are those likely to buckle up (selective recruitement); (3) belt effectiveness estimates that ignore selective recruitenment are biased upwards by large amounts; (4) belts appear more effective at preventing fatalities than at preventing injuries; and (5) the results are consistent with a prior estimate, derived using a method unaffected by the biases discussed here, which found that, averaged over all crashes, safety belts reduce driver fatality risk by (42 plus or minus 4) percent.
