In 2013, 10,076 persons died in crashes in which at least one driver had a blood alcohol concentration (BAC) ≥0.08 grams per deciliter (g/dL), the legal limit for adult drivers in the United States .
To estimate the prevalence, number of episodes, and annual rate of alcohol-impaired driving, CDC analyzed self-reported data from the 2012 Behavioral Risk Factor Surveillance System (BRFSS) survey.
An estimated 4.2 million adults reported at least one alcohol-impaired driving episode in the preceding 30 days, resulting in an estimated 121 million episodes and a national rate of 505 episodes per 1,000 population annually.
Alcohol-impaired driving rates varied by more than fourfold among states, and were highest in the Midwest U.S. Census region. Men accounted for 80 percent of episodes, with young men aged 21–34 years accounting for 32 percent of all episodes.
Additionally, 85 percent of alcohol-impaired driving episodes were reported by persons who also reported binge drinking, and the 4 percent of the adult population who reported binge drinking at least four times per month accounted for 61 percent of all alcohol-impaired driving episodes.
Effective strategies to reduce alcohol-impaired driving include publicized sobriety checkpoints, enforcement of BAC laws, requiring alcohol ignition interlocks for everyone convicted of driving while intoxicated, and increasing alcohol taxes .
Annual alcohol-impaired driving episode rates varied more than fourfold among states, from 217 (Utah) to 995 (Hawaii) per 1,000 population. The Midwest U.S. Census region had the highest annual alcohol-impaired driving rate at 573 per 1,000 population.
