Driving risk is measured through deaths, injuries, exposure rates, behavior-related crash classifications and protective-equipment outcomes. The statistics below focus mainly on the United States, with clearly labeled global estimates from the World Health Organization (WHO), and distinguish final counts from early projections and evidence syntheses.
Key Driving Risk Statistics
The most broadly useful driving risk figures include:
- 39,345 people were projected to die in U.S. traffic crashes in 2024, an early estimate 3.8% below the 40,901 deaths reported for 2023.
- The U.S. traffic fatality rate was 1.20 deaths per 100 million vehicle miles traveled in 2024, using preliminary fatality and mileage estimates.
- U.S. traffic deaths fell from 42,721 in 2022 to 40,901 in 2023, according to final figures.
- Alcohol-impaired crashes killed 13,384 people in the United States in 2021, under NHTSA’s definition of a driver or rider with BAC at least 0.08 g/dL.
- Alcohol-impaired deaths represented 31% of U.S. motor-vehicle fatalities in 2021.
- At least 648 U.S. drowsy-driving fatalities were identified in 2021, a documented minimum because drowsiness is difficult to establish after a crash.
- Distraction-affected crashes killed 3,308 people and injured an estimated 289,310 people in the United States in 2022.
- Approximately 12,330 people were killed in speeding-related U.S. crashes in 2021.
- Correct motorcycle-helmet use can reduce brain-injury risk by up to 74%, according to WHO’s global evidence synthesis.
- Seat-belt use can reduce vehicle-occupant death risk by up to 50%, according to WHO’s global evidence synthesis.
- The fatal-crash rate per mile for U.S. drivers aged 16–19 was just over three times the rate for drivers aged 20 and older, in an IIHS National Household Travel Survey-based analysis.
- Motorcyclists had 31.39 fatalities per 100 million vehicle miles traveled in 2023, compared with 1.13 for passenger-car occupants in the United States.
- A total of 6,335 motorcyclists were killed in U.S. traffic crashes in 2023, representing 15% of all traffic fatalities.
- Approximately 1.16 million people die in road crashes worldwide each year, according to WHO’s global estimate.
- An estimated 20–50 million more people suffer nonfatal road injuries worldwide each year, many with disabling consequences.
- Transportation incidents accounted for 36.8% of U.S. fatal work events in 2023, totaling 1,942 deaths.

Overall Driving Risk Statistics and U.S. Traffic Trends
NHTSA’s final figures show 42,721 U.S. traffic deaths in 2022 and 40,901 in 2023, a decrease of 1,820 deaths, or 4.3%. The fatality rate also declined from 1.34 to 1.26 deaths per 100 million vehicle miles traveled over the same period.
| Measure | Earlier period | Later period | Geography and status |
|---|---|---|---|
| Traffic deaths | 42,721 (2022) | 40,901 (2023) | United States; final figures |
| Fatality rate | 1.34 per 100 million VMT (2022) | 1.26 (2023) | United States; final 2023 rate |
| Vehicle miles traveled | — | 1% increase in 2024 | United States; preliminary mileage estimate |
| Traffic deaths | 40,901 (2023) | 39,345 projected (2024) | United States; 2024 early projection |
NHTSA Releases 2023 Traffic Deaths, 2024 Estimates reports that the 2024 estimate is preliminary and uses preliminary FHWA mileage data. The same release records a 1% increase in U.S. vehicle miles traveled from 2023 to 2024.
An earlier NHTSA release estimated 40,990 deaths in 2023, 3.6% below the 42,514 reported for 2022, and estimated that VMT rose by about 67.5 billion miles, or 2.1%, in 2023. Because later final figures are available, these earlier estimates should be treated as historical projections rather than substitutes for the final totals.
More than 1,000 communities received $1.7 billion in Safe Streets and Roads for All grants in 2023. This measures funding and reach, not a measured reduction in crash risk. NHTSA Releases 2022 Traffic Deaths, 2023 Early Estimates provides the grant and early-estimate figures.
Alcohol, Drug and Drowsy Driving Risk Statistics
Alcohol impairment is one of the clearest behavior-specific categories in U.S. fatal-crash data. NHTSA counted 13,384 alcohol-impaired traffic deaths in 2021, defined as crashes involving a driver or motorcycle rider with BAC at least 0.08 g/dL.
- Alcohol-impaired deaths rose 14.2%, from 11,718 in 2020 to 13,384 in 2021.
- Alcohol-impaired deaths were 31% of total U.S. motor-vehicle fatalities in 2021.
- In the NHTSA series, alcohol-impaired-driving fatalities fell 53% from 1982 to 2011, then increased 36% from 2011 to 2021; NHTSA notes that pandemic-era increases contributed to the latter change.
NHTSA’s Countermeasures That Work: Alcohol-Impaired Driving supplies the 2021 count, share and long-run comparisons. The same source’s rounded 2021 briefing figure of 12,600 fatalities uses a broader impairment framing and should not be treated as identical to the BAC-defined series.
WHO reports that crash risk rises significantly when a driver’s BAC reaches at least 0.04 g/dL. This is a global evidence synthesis and threshold statement, not a single-country crash count.
NHTSA materials identify at least 648 drowsy-driving fatalities in 2021. That figure is a documented minimum because drowsiness is difficult for investigators to identify reliably after a crash.
Speeding, Distracted Driving and Intersection Risk Data
NHTSA reported 3,308 deaths and an estimated 289,310 injuries in distraction-affected U.S. crashes in 2022. The same category included 621 vulnerable road users—pedestrians, cyclists and other non-occupants—who were killed that year.
Speeding-related crashes killed approximately 12,330 people in the United States in 2021. NHTSA materials also cite approximately 12,400 distraction fatalities for 2021, but distraction is often missing from police reports, so neither classification measures all exposure to the behavior.
The Federal Highway Administration reviewed a historical 1999–2000 sample of fatal intersection crashes. Its findings describe a selected study sample rather than current national prevalence:
- In 889 fatal multiple-vehicle crashes with light-vehicle violations at signals, drivers failed to obey the signal in 67% of signal crashes and failed to yield in 33%.
- About 82% of multiple-vehicle fatal crashes at traffic signals occurred on urban roads, while about 57% of comparable stop-sign crashes occurred on rural roads.
- Speeding occurred in 33% of single-vehicle crashes in the review, compared with inattention in 14%.
- In two-vehicle fatal crossing-path crashes, distraction was reported for about 11% of light-vehicle violations.
- Speeding or racing was related to 10% of light-vehicle violations in multiple-vehicle fatal crashes.
These proportions come from FHWA’s Human Factors Literature Review. The study’s age and selected fatal-crash sample mean the figures should not be read as modern rates for all drivers.
Seat-Belt, Helmet and Child-Restraint Statistics
Protective measures change the severity of outcomes, but WHO’s estimates are maximum or evidence-synthesis effects rather than guarantees for an individual occupant. The estimates cover global evidence and do not represent one U.S. crash series.
| Protective measure | Estimated outcome | Scope |
|---|---|---|
| Correct motorcycle-helmet use | Up to 74% lower brain-injury risk | Global WHO evidence synthesis |
| Seat-belt use | Up to 50% lower vehicle-occupant death risk | Global WHO evidence synthesis |
| Child restraints | 71% lower infant deaths | Global evidence; infants |
WHO’s Road Traffic Injuries fact sheet emphasizes that helmet fit and correct use affect the protective result, and that the child-restraint estimate concerns infants rather than all children.
U.S. 2023 motorcycle-death data show a large difference between helmet-law groups. In states without universal helmet laws, 51% of motorcyclists killed were not wearing helmets among cases with known helmet use, compared with 10% in states with universal helmet laws.
Unknown helmet-use cases are excluded, and the state groups are not randomized comparisons.
Teen, Older-Driver and Motorcycle Risk Statistics
Risk varies with both age and the denominator used. IIHS reports that the fatal-crash rate per mile for U.S. drivers aged 16–19 is just over three times the rate for drivers aged 20 and older, while its long-run population-based comparisons show declines for every listed age group from 1975 to 2024.
| Age group | Change in passenger-vehicle drivers involved in fatal crashes per 100,000 people, 1975–2024 |
|---|---|
| 16–19 | 64% decline |
| 20–34 | 50% decline |
| 35–69 | 35% decline |
| 70 and older | 23% decline |
The age trends are population-based and are not the same as miles-driven risk. In 2024, 3,057 passenger-vehicle drivers aged 16–19 were involved in fatal crashes: 41% in single-vehicle crashes and 59% in multiple-vehicle crashes.
These are drivers involved in fatal crashes, not teen fatalities or a probability of crashing.
The figures come from IIHS Fatality Facts 2024: Teenagers, which combines the mileage comparison with FARS-based age trends.
Motorcycle exposure has a much higher fatality rate per vehicle mile than passenger-car occupancy in the cited 2023 U.S. comparison. Motorcyclists recorded 31.39 fatalities per 100 million VMT versus 1.13 for passenger-car occupants—nearly 28 times the passenger-car occupant rate in NHTSA’s rounded comparison.
NHTSA counted 6,335 motorcyclists killed in U.S. traffic crashes in 2023, or 15% of all traffic fatalities, and estimated 82,564 motorcyclist injuries. Motorcyclist fatalities among people aged 15–20 rose 44%, from 350 in 2022 to 505 in 2023; among riders who died in single-vehicle motorcycle crashes in 2023, 41% were alcohol impaired.
NHTSA’s Motorcycle Safety Month release notes that vehicle-class rates are not directly comparable for exposure, vehicle use and rider characteristics.
Pedestrian, Bicyclist and Work-Related Road Risk Statistics
WHO estimates that approximately 1.16 million people die in road crashes worldwide each year, with another 20–50 million suffering nonfatal injuries. WHO also estimates that 92% of global road deaths occur in low- and middle-income countries, which have around 60% of the world’s vehicles.
Road crashes cost most countries about 3% of GDP, according to WHO. This is a macroeconomic estimate, not a direct measure of household, insurer or individual-driver cost.
In the United States, bicyclists account for about 2%–3% of motor-vehicle crash deaths each year. IIHS recorded 1,075 bicyclists killed in crashes with motor vehicles in 2024; that total was 7% higher than in 1975 and 73% higher than the 2010 low.
- People aged 20 and older made up 89% of U.S. bicyclist deaths in 2024, an age share rather than an age-specific exposure risk.
- Bicyclist deaths among people younger than 20 declined 88% from 1975 to 2024, a count trend rather than a mileage-adjusted risk rate.
The bicyclist figures are from IIHS Fatality Facts 2024: Bicyclists, based on the historical FARS series.
Work-related transportation is a separate measurement frame. The Bureau of Labor Statistics recorded 5,283 fatal work injuries in the United States in 2023, including a rate of 3.5 per 100,000 full-time-equivalent workers; transportation incidents represented 36.8% of all fatal work events, or 1,942 deaths.
In transportation and warehousing, 930 fatal work injuries occurred in 2023, down 11.7% from 1,053 in 2022. Transportation incidents accounted for 71.7% of that sector’s fatal work injuries, or 667 deaths, including 249 roadway collisions with another vehicle and 193 collisions with another object.
Transportation and material-moving occupations recorded 1,495 fatal work injuries in 2023, the highest occupational-group total. These BLS CFOI measures include workplace classifications and are not a census of ordinary private driving or commuting exposure; the source is the BLS 2023 Census of Fatal Occupational Injuries release.
