Alcohol-impaired driving remains a major public safety burden. Globally, road traffic crashes are linked to 1.3 million deaths each year, and alcohol is associated with 25 to 35% of traffic crashes. In the US, alcohol-impaired driving accounts for 14% of all traffic fatalities, so the focus here is how specific countermeasures reduce crashes and repeat DUI.
Key Takeaways
- Of all traffic fatalities in the US, 14% involve alcohol-impaired driving
- Ignition interlocks reduce fatal crashes involving drunk driving by 42% (systematic review finding)
- DUI prevention programs reduce recidivism by about 10%–20% depending on program type (systematic review)
- Drink driving laws with vehicle impoundment for repeat offenders reduce recidivism by 19% (evaluation study)
- Ignition interlock programs cost between $70 and $200 per month in typical US implementations (state program fee schedules vary)
- Ignition interlocks reduce repeat DUI by 67% in a large US study (meta-analysis)
- NHTSA estimates the societal cost of crashes in the US was about $242 billion in 2010 (conservative estimate)
- Ignition interlocks are mandated for repeat DUI offenders in many US states (varies by state); at least 50+ states have some form of interlock law
- WHO reports that 1.3 million deaths per year are attributed to road traffic crashes globally
- 3.1% of US adults reported driving under the influence in 2019 (NSDUH)
- Among US high school students, 8.2% reported driving after drinking alcohol during the past 30 days (YRBS)
- Drivers with BAC 0.15+ are about 11.0 times more likely to be involved in a fatal crash than sober drivers (peer-reviewed meta-analysis)
- 0.08+ BAC is associated with about 3.0x crash risk (meta-analysis)
- Alcohol impairment reduces driving performance: reaction time increases by about 0.2–0.4 seconds at moderate intoxication in simulator studies (peer-reviewed)
- 1,360,000 estimated road deaths per year globally are attributed to alcohol use (including passengers) in 2016.
Alcohol-impaired driving causes 14% of US traffic deaths, but interlocks, checkpoints, and tougher laws sharply cut recidivism and fatalities.

Economics & Costs Interpretation
From an economics and costs perspective, ignition interlocks typically run about $70 to $200 per month with installation costs around $100 to $300, yet they can cut repeat DUI by 67%, which helps explain why reviews find them cost effective even while the broader societal price of crashes is estimated at about $242 billion in 2010 and harmful alcohol use costs roughly 1% of global GDP.
