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 < 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 < 0.001); speeding (74% vs. 58%, p < b.05); and reckless driving (68% vs. 44%, p < 0.002). Of the surviving culpable impaired MCTDs (n = 48), 16.7% received crash-related convictions. 12.5% received alcohol-related convictions. The reasons for the low conviction rates are probably multifactoral.
