Alcohol use, driving records, crash culpability, and crash conviction rates for 165 injured motorcycle drivers (MTCDs) were studied.Of the 165 MTCDs, 53.3% tested positive for alcohol (BAC+). Culpability determinations (n.150) revealed that 83% of BAC+ and 46% of BAC-MTCDs caused their crashes (p less than 0.001). Driving records (n.145) revealed the following prevalence of one or more convictions for BAC+ and BAC-MTCDs; impaired driving (29% vs. 7%, p less than 0.001); speeding (74% vs. 58%, p less 0.05); and reckless driving (68% vs. 44%, p less than 0.002). Of the surviving culpable impaired MTCDs(n.48), 16.7% received crash-related convictions, 12.5% received alcohol-related convictions. The reasons for the low conviction rates are probably multifactoral. (A).
