Every $1 spent on enforcement and penalties for alcohol-impaired driving can return $5 or more in societal benefits, according to a 2022 synthesis of public health and transport research. Yet the toll is still stark, with about 100,000 road deaths globally attributed to drink-driving each year. The figures below unpack where the risk concentrates and which countermeasures are showing measurable impact.
Key Takeaways
- In 2022, alcohol-impaired crashes involved impaired drivers in 95% of cases (where impairment was detected/measured)
- In 2019, 2.5 million people in the U.S. were injured in alcohol-impaired driving crashes (including nonfatal injuries)
- In 2019, the number of alcohol-related road crashes in the U.S. was estimated at 1.3 million
- Alcohol-impaired driving is associated with about 27% of crash-related economic costs in the United States (NSC share estimate, 2021)
- In 2022, a review of public health and transport policy found that every $1 spent on enforcement and penalties for alcohol-impaired driving yields $5+ in societal benefits (systematic evidence synthesis)
- WHO estimates 100,000 people died in road traffic crashes due to drunk driving each year
- The Global Status Report on Road Safety 2018 reports that 54 countries have implemented a legal BAC limit of 0.05 g/dL or lower (and 12 have limits above 0.08 g/dL)
- A NHTSA review reports that ignition interlock programs reduce recidivism among offenders by about 30% compared with no interlock
- A 2018 NHTSA report on sobriety checkpoints concludes that checkpoints can reduce alcohol-related fatal crashes by 9% compared with control periods
- In Australia, 2022 data reported that 25% of fatally injured drivers had BAC above 0.05
- 10,381 people were killed in alcohol-impaired driving crashes in the United States in 2016
- In 2021, 16,000 people in the United States died in impaired-driving crashes
- The International Transport Forum estimated that drink-driving contributes to about 100,000 road deaths globally each year
- In 2022, 23 countries had a mandatory administrative license suspension system for certain levels of alcohol impairment (ITF/International traffic policy review)
- As of 2023, 16 countries use random breath testing in the context of traffic policing (Global benchmark summary)
Alcohol-impaired driving kills tens of thousands each year, and proven enforcement like ignition interlocks and sobriety checkpoints saves lives.

In 2019, 2.5 million people in the U.S. were injured in alcohol-impaired driving crashes (including nonfatal injuries)
Interpretation
Road Fatalities Interpretation
For road fatalities, alcohol-impaired drivers were detected in 95% of alcohol-impaired crashes in 2022, and the scale of harm is enormous because 2.5 million people were injured in the U.S. from alcohol-impaired driving crashes in 2019, showing that this issue drives both fatal and widespread nonfatal losses.

A 2022 report estimated that impaired-driving programs (interlocks, checkpoint staffing, and enforcement) can produce benefit-cost ratios above 10:1 (transport safety program evaluation)
Interpretation
Cost Analysis Interpretation
Cost analysis shows that alcohol-impaired driving drives roughly 27% of the United States’ crash-related economic costs, yet targeted enforcement and impaired-driving programs deliver sizable returns, with evidence that every $1 spent can yield $5 or more in societal benefits and benefit cost ratios above 10 to 1.

Interpretation
Policy & Enforcement Interpretation
Under Policy and Enforcement measures, evidence shows that sobriety checkpoints and random breath testing can cut alcohol related fatal or injury crashes by around 9%, while ignition interlock programs substantially lower repeat offenses by roughly 17% to 30%, and many countries have tightened drunk driving laws to a 0.05 g/dL BAC limit.
