Fatality Facts 2017Alcohol

Alcohol

The probability of a fatal crash rises significantly after 0.05 percent blood alcohol concentration (BAC) and even more rapidly after 0.08 percent. Zador, P.L.; Krawchuck, S.; and Voas, R.B. 2000. Alcohol-related relative risk of driver fatalities and driver involvement in fatal crashes in relation to driver age and gender: an update using 1996 data. Journal of Studies on Alcohol 61:387-95. Voas, R.B.; Torres, P.; Romano, E.; and Lacey, J.H. 2012. Alcohol-related risk of driver fatalities: an update using 2007 data. Journal of Studies on Alcohol and Drugs 73(3):341-350.

Drivers with very high BACs (at or above 0.15 percent) have a very high risk of dying in a crash or getting severely injured. Zador, P.L.; Krawchuck, S.; and Voas, R.B. 2000. Alcohol-related relative risk of driver fatalities and driver involvement in fatal crashes in relation to driver age and gender: an update using 1996 data. Journal of Studies on Alcohol 61:387-95. , Peck, R.C.; Gebers, M.A.; Voas, R.B.; and Romano, E. 2008. The relationship between blood alcohol concentration (BAC), age, and crash risk. Journal of Safety Research 39:311-19.All states have laws making it a crime to drive with a BAC at or above 0.08 percent. Utah passed a law making it a crime to drive with a BAC at or above 0.05 percent. This law will take effect on Dec. 30, 2018.

Substantial progress was made from 1982 to the mid-1990s in reducing the numbers and proportion of fatally injured drivers with BACs at or above 0.08 percent. However, little subsequent progress has been made, and alcohol-impaired driving is still a major problem. Institute research estimated that 7,082 deaths would have been prevented in 2010; if all drivers with BACs of 0.08 percent or higher were kept off the roads. Lund, A.K.; McCartt, A.T.; and Farmer, C.M. 2012. Contribution of alcohol-impaired driving to motor-vehicle crash deaths in 2010. Arlington, VA: Insurance Institute for Highway Safety.Applying the same methods yields an estimate of 7,426 preventable deaths if all drivers with BACs of 0.08 percent or higher were kept off the roads in 2017.

At the same BAC, drivers younger than 21 are far more likely than older drivers to get into a fatal or nonfatal crash. Zador, P.L.; Krawchuck, S.; and Voas, R.B. 2000. Alcohol-related relative risk of driver fatalities and driver involvement in fatal crashes in relation to driver age and gender: an update using 1996 data. Journal of Studies on Alcohol 61:387-95. Voas, R.B.; Torres, P.; Romano, E.; and Lacey, J.H. 2012. Alcohol-related risk of driver fatalities: an update using 2007 data. Journal of Studies on Alcohol and Drugs 73(3):341-350. Peck, R.C.; Gebers, M.A.; Voas, R.B.; and Romano, E. 2008. The relationship between blood alcohol concentration (BAC), age, and crash risk. Journal of Safety Research 39:311-19.The minimum drinking age is 21 throughout the United States. In addition, all states have "zero tolerance" laws that prohibit people younger than 21 from driving after drinking. In recent years, drivers younger than 21 killed in crashes are about half as likely as fatally injured drivers ages 21-30 to have a BAC of 0.08 percent or higher.

The information in this fact sheet is based on data from all 50 states and the District of Columbia with imputations for missing BACs provided by the U.S. Department of Transportation's multiple imputation model. Subramanian, R. 2002. Transitioning to multiple imputation — a new method to impute missing blood alcohol concentration (BAC) values in FARS. Report no. DOT HS-809-403.

The following facts are based on analysis of data from the U.S. Department of Transportation's Fatality Analysis Reporting System (FARS).

Age and gender

Among fatally injured passenger vehicle drivers in 2017, a higher proportion of males than females had BACs at or above 0.08 percent at every age. Overall, 32 percent of males and 20 percent of females had BACs at or above 0.08 percent. The percentage was highest among males ages 21-30. The lowest percentage was observed among females older than 70. Drivers younger than age 21 who were killed in crashes had far lower percentages of BACs of 0.08 percent or greater than drivers ages 21-30 who died: 22 percent versus 42 percent in 2017.

Since the 1980s the percentage of fatally injured passenger vehicle drivers with BACs at or above 0.08 percent has declined more among 16-20 year-olds than among older drivers. The percentage of fatally injured 16-20 year-old passenger vehicle drivers with BACs at or above 0.08 percent now is substantially lower than drivers ages 21-50.

When alcohol-impaired crashes occur

Alcohol involvement in fatal crashes peaks at night. Between 9 p.m. and 6 a.m., 52 percent of fatally injured passenger vehicle drivers in 2017 had BACs at or above 0.08 percent, compared with 17 percent during other hours.

Alcohol involvement is very high in fatal nighttime (9 p.m. to 6 a.m.) single-vehicle crashes. In 2017, 61 percent of fatally injured passenger vehicle drivers in these crashes had BACs at or above 0.08 percent, and 46 percent had BACs at or above 0.15 percent. Six percent had BACs of 0.01 to 0.07 percent.
