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.

05
Ignition interlock device installation in some US states is about $100–$300 one-time (fee schedules)
06
The cost-effectiveness of ignition interlock has been shown to be favorable: one review finds costs per prevented fatality are typically in the hundreds of thousands (UK study)
07
Sobriety checkpoint programs typically cost law enforcement agencies tens of thousands of dollars per checkpoint event depending on staffing and duration (study estimates)
Interpretation
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.
