Drunk Driving Statistics: Fatalities, Offenders, and Trends

Drunk driving statistics in the United States tell two stories at once: a long-term success and a recent backslide. In 2023, alcohol-impaired drivers were involved in fatal crashes that killed 12,429 people, about one death every 42 minutes, and impaired driving accounted for roughly 30% of all traffic fatalities.¹ The rate of alcohol-impaired driving deaths per 100,000 people has fallen 59% since 1982, but the raw death toll is higher today than it was before the pandemic. The headline numbers below use the federal definition of alcohol impairment: a blood alcohol concentration (BAC) of 0.08% or higher.

How Often Drivers Are Actually Impaired

Arrests capture only a fraction of impaired driving. In 2020, about 1.5% of U.S. adults told federal surveyors they had driven after drinking too much in the previous 30 days. Extrapolated over a year, that works out to roughly 125 million episodes of alcohol-impaired driving.²

For every DUI arrest, in other words, hundreds or thousands of impaired trips go undetected. That gap is why fatality figures can stay high even in years when arrests dip.

Fatalities by Year: 2020 Through 2023

Alcohol-impaired crash deaths jumped sharply during the pandemic and have only partially eased since. Fewer people were driving in 2020, but those who did drive appeared to take bigger risks, and the effect carried into the following years.

2020: 11,718 fatalities in alcohol-impaired crashes.³
2021: 13,384 fatalities, a 14.2% jump over 2020 and 31% of all traffic deaths.³
2022: 13,524 fatalities, 32% of all traffic deaths and the highest raw total in this span.⁴
2023: 12,429 fatalities, 30% of all traffic deaths.¹

The 2023 drop is real, but the number is still well above 2020, and the share of all traffic deaths tied to impairment has barely moved.

Who Drives Drunk

Age

Drivers between 21 and 24 have the highest rate of alcohol impairment in fatal crashes. In 2023, 28% of drivers in that age group involved in fatal crashes had a BAC of 0.08% or higher. Drivers 25 to 34 were close behind at 26%.¹

The pattern is stable. In 2022, the 21-to-24 group accounted for 29% of alcohol-impaired drivers in fatal crashes, and in 2021 both the 21-to-24 and 25-to-34 groups sat at 27%.⁵³

Sex

Men make up the overwhelming majority of impaired drivers in fatal crashes. In 2023, there were roughly four male alcohol-impaired drivers in fatal crashes for every one female: 9,155 to 2,339.¹ The 2022 breakdown looked much the same, at 9,914 men and 2,562 women.⁵

The gap holds across every age band. It is one of the most stubborn features of the data.

When and Where Impaired Crashes Happen

Impaired driving is concentrated in a few predictable windows. In 2022, the share of drivers in fatal crashes who were alcohol-impaired was almost three times higher at night (32%) than during the day (11%). In raw numbers, 9,679 alcohol-impaired drivers were in fatal nighttime crashes that year, compared with 3,146 during the day.⁵

Weekends are worse than weekdays. In 2022, 29% of drivers in fatal weekend crashes were alcohol-impaired, versus 17% during the week.⁵ Saturday nights and early Sunday mornings sit at the peak, with Friday nights close behind.

Rural areas also carry more risk per capita than urban ones. FBI data has shown rural DUI arrest rates nearly double those in metropolitan communities, a gap that reflects fewer transit options, longer driving distances, and lighter enforcement presence.

Drugs Beyond Alcohol

Drug-impaired driving is a growing share of the problem. In 2018, about 4.7% of people 16 and older reported driving under the influence of marijuana, and 0.9% reported driving under the influence of other illicit drugs. By comparison, 8.0% reported driving after drinking too much.⁶

Among fatally injured drivers with known drug test results in 2021, 52% tested positive for legal or illegal drugs. Many of those drivers also had alcohol in their system, so the alcohol and drug figures overlap rather than add cleanly.

Repeat Offenders and the Interlock Effect

About one in four people arrested for impaired driving has a prior DUI arrest. An NHTSA analysis put the repeat-offender share of DUI arrests at 25%, down from 31% in 1995 but still high, with state-level rates ranging from 11% to 41%.⁷

Ignition interlock devices, which lock a car’s ignition if the driver’s breath registers alcohol, cut re-arrest rates by about 75% while installed, according to a CDC review. Once the device is removed, though, re-arrest rates for interlock users drift back toward the rates of drivers who never had one, so the effect is mechanical rather than rehabilitative.⁸

Thirty-one states and the District of Columbia require interlocks for all DUI convictions, including first offenses. Eight more require them for repeat offenders or high-BAC cases, and five require them only for repeat offenders.⁹

The Long Arc Since 1982

The per-capita fatality rate for alcohol-impaired driving fell 59% between 1982 and 2023. That decline tracks decades of policy changes: a national drinking age of 21, a 0.08% BAC threshold in every state, zero-tolerance laws for drivers under 21, administrative license suspension, and the spread of sobriety checkpoints and awareness campaigns.

The recent numbers show the limits of those gains. Deaths climbed from 11,718 in 2020 to 13,384 in 2021 (up 14.2%), edged higher to 13,524 in 2022, then fell to 12,429 in 2023.³¹ Across all four years, the impaired-driving share of total traffic deaths stayed between 30% and 32%. The biggest wins of the 1980s and 1990s are already banked; further reductions likely depend on wider interlock mandates, more ride-hailing use, and vehicle-based alcohol detection technology that is not yet standard.
