Facts + Statistics: Alcohol-impaired driving

Alcohol-impaired crashes are those that involve at least one driver or a motorcycle operator with a blood alcohol concentration (BAC) of 0.08 grams per deciliter or above, the legal definition of impaired driving. According to NHTSA 10,142 people died in alcohol-impaired crashes in 2019. Alcohol-impaired crash fatalities accounted for 28 percent of all crash fatalities.

Alcohol is a major factor in traffic crashes. Based on data from the U.S. Department of Transportation, National Highway Traffic Safety Administration (NHTSA), 10,142 people died in alcohol-impaired crashes in 2019. These crashes involve at least one driver or motorcycle operator with a blood alcohol concentration (BAC) of 0.08 grams per deciliter or above, the legal definition of impaired driving in most states. According to NHTSA, alcohol-impaired crash fatalities accounted for 28 percent of all crash fatalities in 2019, the lowest proportion on record.

The Federal Bureau of Investigation estimates 1,024,508 drivers were arrested for driving under the influence of alcohol or narcotics in 2019. The arrest rate works out to one arrest for about every 222 licensed drivers in the United States.

All states and the District of Columbia except Utah define impairment as driving with a BAC (blood alcohol concentration) at or above 0.08 grams per deciliter. In Utah the BAC limit was lowered to 0.05 in 2018. Law enforcement officials have been able to measure BAC accurately for decades, and the results obtained from testing devices is accepted in almost all jurisdictions in the United States.

Campaigns against alcohol-impaired driving especially target drivers under the age of 21, repeat offenders and 21-to 34-year-olds, the age group that is responsible for more alcohol-related fatal crashes than any other. Young drivers are those least responsive to arguments against impaired driving, according to NHTSA.

To make sellers and servers of liquor more careful about to whom and how they serve drinks, 42 states and the District of Columbia have enacted laws or have case law holding commercial liquor servers legally liable for the damage, injuries and deaths an alcohol-impaired driver causes. Thirty-eight states have enacted laws or have case law that permit social hosts who serve liquor to people who subsequently are involved in crashes to be held liable for any injury or death.
