Road traffic crashes cost the world an estimated $2.0 trillion every year, and alcohol is tied to a substantial share of the harm. In the U.S., there were 1.22 million alcohol-impaired driving charges filed in 2022, yet strategies like ignition interlocks and lower BAC limits can cut repeats and crash risk. We pulled together the latest statistics across policy, enforcement, and outcomes to show what actually changes after a driver drinks and drives.
Key Takeaways
- $2.0 trillion is estimated annual global economic loss from road traffic crashes (WHO global estimate; includes injuries and deaths)
- The WHO estimates about 3% of GDP is lost due to road traffic injuries globally
- Ignition interlock devices have annual per-driver program costs typically in the hundreds of dollars (U.S. interlock program cost ranges reported in evaluations)
- WHO estimates that 43% of adults worldwide consume alcohol at least occasionally (background behavior context)
- In 2022, 6.5% of U.S. adults reported driving under the influence in the past year (survey estimate)
- In a global survey of alcohol use, men were more likely than women to drink and drive (meta-analysis estimate: 1.7x higher odds for men)
- Between 2007 and 2016 in the U.S., about 70% of teen traffic deaths involved alcohol (fatalities with alcohol presence in fatally injured drivers or victims, per study)
- In 2022, there were 1.22 million alcohol-impaired driving charges filed in the U.S. (estimate)
- Enforcement operations (e.g., DUI checkpoints) are associated with a 20% reduction in alcohol-impaired driving crashes in meta-analyses (average effect size)
- Ignition interlock programs can reduce recidivism by 26% to 30% on average compared with no interlock (systematic review estimate)
- Lowering the legal BAC limit from 0.08 to 0.05 has been associated with about a 6% reduction in road fatalities from 0.05-0.08 drivers (systematic review estimate)
- In 2022, there were 2.0 alcohol-impaired driving fatalities per million population in the U.S. (rate)
- In Australia, 1,279 people died in alcohol-impaired driving crashes in 2020 (annual count; jurisdictional reporting summary)
- Alcohol-impaired driving deaths in Australia were 34% of all road fatalities in 2020 (share)
- In 2021, 16 U.S. states required ignition interlocks for all offenders (state requirement coverage count)
Road safety research shows strong interventions like lower BAC limits and ignition interlocks can cut alcohol impaired crashes.

A 2020 OECD report estimates that road safety spending can yield economic returns of 3:1 to 20:1 depending on intervention (range)
06
In 2021, the U.S. spent about $250 million on DUI enforcement and related road safety programs through federal grants (FHWA/ NHTSA grant allocations)
07
The WHO estimates that alcohol contributes to 10% of the global burden of disease in injury categories linked to alcohol use (global burden estimate)
Interpretation
Cost & Economic Impact Interpretation
Even though ignition interlock programs typically cost only hundreds of dollars per driver, global road traffic injuries impose losses of about 3% of GDP and alcohol accounts for roughly 10% of the injury burden, so relatively targeted DUI enforcement and prevention efforts can deliver strong cost effectiveness within the Cost and Economic Impact category, with broader road safety spending returning between 3:1 and 20:1.

Interpretation
Public Attitudes & Behavior Interpretation
Under the Public Attitudes and Behavior lens, the fact that 6.5% of U.S. adults reported driving under the influence in the past year and that men are about 1.7 times more likely than women to drink and drive shows that risky driving behaviors persist even though most alcohol use is only occasional for many adults worldwide.
