The objective of the present research is to re-examine and refine relative fatal crash risk estimates in a systematic fashion using more recent data. The study was based on U.S. data on drivers in fatal crashes during 1995 and 1996 obtained from the Fatality Analysis Reporting System (NHTSA, FARS) and driver exposure data obtained from the 1996 National Roadside Survey (Voas et al., 1997). It extends similar prior work by the first author in three important ways. Firstly, the authors estimate relative risk for the policy-relevant BAC range between 0.08% and 0.10%. Secondly, the authors estimate relative risk for six driver groups: (1) Driver fatalities in single vehicle crashes, (2) Driver involvements in single vehicle fatal crashes, (3) Driver fatalities in two vehicle crashes, (4) Driver invovlements in two vehicle fatal crashes, (5) Driver fatalities in all crashes, and (6) Driver involvement in all fatal crashes. Thirdly, the authors employ statistical methods to estimate both the effect of sampling roadside exposure, and the effect of multiple imputation of missing BACs on the uncertainty of relative risk estimates.
