Samenvatting
Induced exposure, a technique whereby not-at-fault driver crash involvements are used as the denominator in a risk estimate calculation, was used to estimate fatal crash risk by driver BAC. One important advantage of induced exposure is that large existing data sets provide substantial sample size for risk estimation. Risk ratios were calculated for BACs ranging from .01% to .20%. The results indicated that whereas case/control methods suggest an exponential or curvilinear relationship between crash risk and BAC, both induced exposure and laboratory findings suggest a linear relationship.
