DWI History of Fatally Injured Pedestrians

The number of fatally injured drivers who had blood alcohol concentrations (BAC) of .08 g/dL or more at the time of their crashes has decreased in recent years in the United States while the number of pedestrians killed at similar BACs has increased. A BAC of .08 g/dL was the legal per se limit for drivers in all States at the time of this study. The objective of this study was to conduct analyses of demographic and driving record data for pedestrians killed in motor vehicle crashes to identify whether those killed with high BACs (.08 g/dL or more) had more prior alcohol-related driving offenses (e.g., DWI, DUI) on their driving records than did fatally injured pedestrians at BACs below .08 g/dL. The study obtained crash information and driving records for fatally injured pedestrians from five States, Florida, Massachusetts, Tennessee, Texas, and Washington. Overall, males represented 71.2 percent of the fatally injured pedestrians (BAC ≥ .08 78.6% male; BAC < .08 65.9% male). For the entire sample, 60 percent was middle-aged (30-59 years), 22 percent were 60+ years old, and 18 percent were less than 30 years old. Most of the BAC ≥ .08 males and females were 30-59 years old (7.0% and 72.5% respectively); 2.5 percent of the BAC ≥ .08 females were 60+ years old compared to 14.3 percent for the males; and 25 percent of the BAC ≥ .08 females were less than 30 years old compared to 15.7 percent of the males. When driving records were available (68.5% of the total sample of fatally injured pedestrians), about 45 percent of the males and 34 percent of the females who were BAC ≥ .08 had prior alcohol-related offenses compared to 21 percent of the males and 14 percent of the females who were BAC < .08. This finding suggests that people with prior alcohol related driving offenses may be at greater risk for being killed as high-BAC pedestrian than those without a prior alcohol offense. The study then identified strategies and countermeasure approaches with the potential to reduce impaired pedestrian fatalities given the study findings. Eight subject matter experts and the project staff generated a total of 50 countermeasure ideas in seven categories (reducing or preventing alcohol use; preventing or limiting/controlling walking or driving after high alcohol consumption; interventions by medical and social service personnel; interventions by law enforcement, courts, and probation; third-party interventions; increased awareness of the problem; and general pedestrian and traffic safety) that could potentially address the problem
