How big is the problem? In 2014, 9,967 people were killed in alcohol-impaired driving crashes, accounting for nearly one-third (31%) of all traffic-related deaths in the United States.1. Of the 1,070 traffic deaths among children ages 0 to 14 years in 2014, 209 (19%) involved an alcohol-impaired driver.1.
Most drunk driving fatalities involved perpetrators who had blood alcohol concentrations (BAC) of at least twice the legal limit, which is 0.08% in most states. In 2012, 61% of offenders in fatal drunk driving accidents had been drinking heavily, with BACs of 0.15% or more.orth Dakota ranked first with a per capita beer consumption rate of 45.8 gallons, while Montana, South Dakota and Texas also ranked in the top 10. In some of the states with the highest fatalities, there were a relatively small number of drunk driving arrests relative to the number of deaths.
