The authors determined the risk of involvement in fatal crashes on Friday and Saturday nights from 10 p.m. to 3 a.m., based upon data from the National Roadside Survey in comparison with data from the Fatality Analysis Reporting System. Among drivers negative for alcohol, white drivers had about half the risk of black drivers (OR=0.49, 95% CI=0.26, 0.90) when other risk factors were controlled. Among drivers with BACs of 0.08% and higher, however, the findings suggest that whites had a greater risk, although this difference did not reach statistical significance (OR=1.64, CI=0.91, 2.97). The racial difference in risk between alcohol-negative drivers and drivers with illegal BACs was not explained by restraint use but may reflect more severe crashes by intoxicated white drivers.
