With 13,524 people dying in alcohol impaired driving crashes in 2022 and 0.6% of U.S. adults aged 18 to 20 reporting drinking and driving in the past month, this post breaks down the age based statistics, legal thresholds, and crash impact behind how the drinking age and enforcement shape outcomes.
Key Takeaways
- 49 states and the District of Columbia have a legal minimum drinking age of 21
- 0.6% of U.S. adults aged 18–20 reported drinking and driving in the past month (2006–2010 pooled data)
- 8% of young adults aged 18–20 reported drinking and driving at least once in the past year (2006–2010 pooled data)
- 13,524 people died in alcohol-impaired driving crashes in 2022
- Alcohol-impaired driving fatalities accounted for 30% of all traffic crash deaths in 2022
- In 2022, 216 people died in alcohol-impaired driving crashes every day on average (13,524/365)
- The CDC reports 1,917 deaths attributed to motor vehicle crashes where alcohol was involved among people aged 18–20 (year referenced in the CDC alcohol and health dataset)
- 18–20 is one of the key age groups the CDC groups for alcohol consumption and driving risk indicators
- 21–24 is a key age group used by CDC for alcohol-related indicators
- The age group 18–20 reported drinking and driving at least once in the past year at 8% (pooled 2006–2010 NHIS)
- The age group 18–20 reported drinking and driving in the past month at 0.6% (pooled 2006–2010 NHIS)
- The NHTSA estimates that enforcing zero tolerance laws for under-21 drivers helps reduce alcohol-impaired driving crashes
Most states set a 21 drinking age, yet 0.6% of 18 to 20 year olds drive drunk monthly.
Legal Framework
149 states and the District of Columbia have a legal minimum drinking age of 21[1]
Verified20.6% of U.S. adults aged 18–20 reported drinking and driving in the past month (2006–2010 pooled data)[2]
Verified38% of young adults aged 18–20 reported drinking and driving at least once in the past year (2006–2010 pooled data)[2]
Verified43% of adults aged 18–20 reported they had ridden with a drunk driver (2006–2010 pooled data)[2]
Directional50.02 is the blood alcohol concentration threshold used in many ‘zero tolerance’ laws for drivers under 21[1]
Single source60.04 is the blood alcohol concentration threshold used in many ‘zero tolerance’ laws for under-21 drivers[1]
Verified70.08 is the blood alcohol concentration threshold commonly used for impairment-related DUI charges for drivers 21 and older in the U.S.[1]
Verified80.08 g/dL (0.08% BAC) is the commonly used per se DUI BAC level in the U.S. for adults 21+[1]
Verified918–20 is the age range most often analyzed for underage drinking and driving in U.S. federal research summaries[2]
Directional10In the U.S., drivers under 21 face ‘zero tolerance’ BAC limits while drivers 21 and older generally face a higher per se limit[1]
Single sourceLegal Framework Interpretation
Across U.S. federal research on ages 18–20, just 0.6% reported drinking and driving in the past month, but the rate rises to 8% over the past year, and this pattern occurs under strict zero tolerance BAC limits of 0.02 to 0.04 for drivers under 21.
Deaths And Injuries
113,524 people died in alcohol-impaired driving crashes in 2022[3]
Verified2Alcohol-impaired driving fatalities accounted for 30% of all traffic crash deaths in 2022[3]
Verified3In 2022, 216 people died in alcohol-impaired driving crashes every day on average (13,524/365)[3]
Verified4In 2021, 13,384 people died in alcohol-impaired driving crashes[4]
Directional5Alcohol-impaired driving fatalities were 29% of all traffic crash deaths in 2021[4]
Single source6In 2017, 10,511 people died in alcohol-impaired driving crashes[5]
Verified7In 2016, 10,497 people died in alcohol-impaired driving crashes[6]
Verified8In 2015, 10,265 people died in alcohol-impaired driving crashes[7]

Verified12In 2003, 16,049 people died in alcohol-impaired driving crashes[10]
VerifiedDeaths And Injuries Interpretation
Despite being lower in recent years than in 2003 when 16,049 people died in alcohol-impaired crashes, fatalities have remained in the 10,000 range, with 13,524 deaths in 2022 making up 30% of all traffic crash deaths and about 216 deaths every day.
Risk By Age
1The CDC reports 1,917 deaths attributed to motor vehicle crashes where alcohol was involved among people aged 18–20 (year referenced in the CDC alcohol and health dataset)[11]
Verified218–20 is one of the key age groups the CDC groups for alcohol consumption and driving risk indicators[11]
Verified321–24 is a key age group used by CDC for alcohol-related indicators[11]
Verified4The NIAAA notes that people aged 18–20 have higher rates of past-month binge drinking than older adults[12]
Directional50.08 BAC is the per se DUI limit for adults 21+ (age threshold relates to impaired-driving charges)[1]
Single source60.02 BAC is a commonly referenced ‘zero tolerance’ limit for drivers under 21 (age threshold relates to impaired-driving charges)[1]
Verified718–20 has a higher prevalence of driving after drinking compared with older age groups in CDC analyses[2]
Verified88% of adults aged 18–20 reported drinking and driving in the past year (2006–2010 pooled data)[2]
Verified90.6% of adults aged 18–20 reported drinking and driving in the past month (2006–2010 pooled data)[2]
Directional10Under-21 zero tolerance enforcement applies specifically to drivers who have not reached 21[1]
Single source1118–20 is the specific age range used for underage driving after drinking prevalence estimates in CDC NHIS-based analyses[2]
Verified1218–20 is the age range used for NHIS estimates of ‘riding with a drunk driver’ exposure[2]
Verified1321+ is used as the comparator age category in CDC ‘alcohol and health’ indicator presentations[11]
VerifiedRisk By Age Interpretation
Even though only 8% of adults aged 18–20 reported drinking and driving in the past year, CDC reports 1,917 alcohol involved crash deaths for this 18–20 group, underscoring how elevated risk among young adults can translate into substantial harm.
Prevention Effectiveness
1The age group 18–20 reported drinking and driving at least once in the past year at 8% (pooled 2006–2010 NHIS)[2]
Verified2The age group 18–20 reported drinking and driving in the past month at 0.6% (pooled 2006–2010 NHIS)[2]
Verified3The NHTSA estimates that enforcing zero tolerance laws for under-21 drivers helps reduce alcohol-impaired driving crashes[1]
Verified4The National Academies review found that raising the minimum legal drinking age reduced alcohol-related crashes among young drivers (review quantitative synthesis)[13]
Directional5NHTSA lists ‘graduated driver licensing’ as a countermeasure with measurable reductions in crash risk for teen drivers[14]
Single source6GDL requirements include multiple stages (learner/conditional) with restrictions that are designed to reduce crash risk among new drivers[14]
VerifiedPrevention Effectiveness Interpretation
Among drivers aged 18–20, the share who reported drinking and driving at least once in the past year is 8% but drops to just 0.6% for the past month, aligning with evidence that policies like zero tolerance, raising the minimum legal drinking age, and graduated driver licensing can reduce alcohol-impaired and teen crash risk.
