Driver behavior statistics span several different measures: crash outcomes, observed protective habits, self-reported conduct, public perceptions and instrumented naturalistic driving. The figures below keep those measures separate while showing how speeding, impairment, distraction, restraint use and attitudes relate to road safety in the United States and selected comparison countries.
Key Driver Behavior Statistics
The most useful headline figures include:
- In the annual baseline cited by a 2016 CDC comparison report, U.S. roads recorded more than 32,000 motor-vehicle deaths and 2 million nonfatal injuries annually.
- Between 2000 and 2013, the U.S. motor-vehicle death rate fell 31%, from 14.9 to 10.3 deaths per 100,000 population.
- In 2013, the United States recorded 32,894 motor-vehicle crash deaths, or 10.3 per 100,000 population.
- In 2015, speeding contributed to 9,723 U.S. motor-vehicle crash deaths, or 27% of the total.
- In 2020, speeding contributed to 11,428 crash deaths, or 29% of U.S. crash deaths.
- In 2024, speeding contributed to 11,288 U.S. crash deaths, or 29% of 39,254 crash deaths.

Driver Behavior Statistics: Crash Scale and Long-Term Safety Trends
Crash statistics describe outcomes associated with behavior, but they are not direct prevalence measures for individual drivers. The CDC’s report cited a broad annual U.S. baseline of more than 32,000 motor-vehicle deaths and 2 million nonfatal injuries, while the observed death rate declined from 14.9 to 10.3 per 100,000 between 2000 and 2013. Vital Signs: Motor Vehicle Injury Prevention — United States and 19 Comparison Countries
| Measure | United States | Comparison context | Period |
|---|---|---|---|
| Crash deaths per 100,000 population | 10.3 | Sweden 2.7; Belgium 6.5; mean 4.4; median 4.1 across 19 countries | 2013 |
| Crash deaths per 100 million vehicle miles | 1.10 | Sweden 0.54; Japan and Spain 1.22; mean 0.85; median 0.80 | 2013 |
| Crash deaths per 10,000 registered vehicles | 1.24 | Comparison range 0.44–1.04; mean 0.68; median 0.66 | 2013 |
| Registered vehicles per 1,000 population | 828 | Comparison range 369–1,080; mean and median 670 | 2013 |
The United States recorded 32,894 crash deaths in 2013. Its rate was 1.10 deaths per 100 million vehicle miles and 1.24 deaths per 10,000 registered vehicles, the highest among the 20 countries in the report; registered vehicles are not equivalent to miles driven.
Country coverage and definitions differ by measure: the CDC analyzed 2000 and 2013 data for selected high-income OECD countries with comparable reported data. These comparisons are outcomes and exposure measures, not causal estimates of driver behavior.
Speeding Behavior Statistics Across Roads and Speed Limits
The Insurance Institute for Highway Safety defines speeding-related fatal crashes using a speeding citation or driver factors such as driving too fast for conditions, racing or exceeding the speed limit. The annual series below shows speeding’s share of U.S. crash deaths rising from 26–27% in 2015–2019 to 29% in 2020.
| Year | Speeding-related deaths | Share of crash deaths |
|---|---|---|
| 2015 | 9,723 | 27% |
| 2016 | 10,291 | 27% |
| 2017 | 9,947 | 27% |
| 2018 | 9,579 | 26% |
| 2019 | 9,592 | 26% |
| 2020 | 11,428 | 29% |
IIHS Fatality Facts: Yearly snapshot reports that in 2024 speeding contributed to 11,288 deaths across all U.S. road types, equal to 29% of 39,254 crash deaths. Road type and posted speed limit show different concentrations:
- Interstates and freeways recorded 1,891 speeding-related deaths, or 29% of deaths on those roads.
- Other major roads recorded 5,543 speeding-related deaths, or 27% of deaths on those roads.
- Minor roads recorded 3,723 speeding-related deaths, or 33% of deaths on those roads.
- Roads posted at 35 mph or less recorded 2,833 speeding-related deaths, or 25% of deaths in that speed-limit group.
- Roads posted at 40–50 mph recorded 3,367 speeding-related deaths, or 30% of deaths in that group.
- Roads posted at 55 mph or higher recorded 4,740 speeding-related deaths, or 42% of deaths in that group.
These are crash-death associations, not observations of how frequently drivers speed. The IIHS road-type total includes other and unknown road types.
Alcohol, Cannabis and Drug-Impaired Driving Statistics
Self-reported surveys and crash-death records answer different questions. The CDC’s 2023 NSDUH estimates cover U.S. residents aged 16 or older who reported past-year conduct, while the 2020 BRFSS figure covers adults reporting behavior in the previous 30 days.
| Measure | Estimate | Population and period |
|---|---|---|
| Drove under the influence of alcohol | 15.5 million; 5.9% | U.S. residents age 16+, previous year, 2023 |
| Drove under the influence of cannabis | 12.1 million; 4.6% | U.S. residents age 16+, previous year, 2023 |
| Drove under the influence of illicit drugs other than cannabis | 2.2 million; 0.8% | U.S. residents age 16+, previous year, 2023 |
| Drove after too much alcohol | 1.5% | U.S. adults, previous 30 days, 2020 |
CDC Impaired Driving Facts says the 2020 adult estimate corresponded to 125 million estimated alcohol-impaired-driving episodes. CDC annualized the reported 30-day episodes by multiplying by 12, so this is not a direct count.
In the CDC’s 2013 international crash comparison, alcohol-impaired driving was involved in 31% of U.S. motor-vehicle crash deaths. Across 18 reporting comparison countries, the share ranged from 3.2% to 33.6%, with a mean of 19.1% and median of 18.0%; Canada was highest at 33.6% in that table.
Speeding was involved in 29% of U.S. crash deaths in 2013. Among 15 comparison countries reporting speeding data, the share ranged from 15% to 42%, with a mean of 28.8% and median of 29.0%; Finland was highest at 42% in the 2013 comparison.
Distracted Driving and Naturalistic Driver Behavior Data
NHTSA recorded 3,308 people killed in U.S. crashes involving distracted drivers in 2022 and estimated 289,310 people injured. The same year, 621 pedestrians, bicyclists and other vulnerable road users were killed in distraction-affected crashes. NHTSA Releases 2022 Traffic Deaths, 2023 Early Estimates
Police-reported distraction can undercount the behavior because it is difficult to establish consistently after a crash. FHWA also reports that driver behavior was a significant factor in more than 90% of U.S. crashes in the 2012 research context, but describes that figure as a broad research summary rather than a single standardized crash-coding estimate.
The SHRP2 Naturalistic Driving Study offers a different measurement approach: 3,147 volunteer drivers aged 16 through 90-plus were followed over one- or two-year periods, with video and vehicle data captured on every trip. The recorded measures included speed, acceleration, braking and other maneuvers. SHRP2 Solutions — Naturalistic Driving Study
Because the SHRP2 participants were volunteers, the sample is not nationally representative. Its strength is detailed observation of driving behavior, not a population prevalence estimate.
Seat Belt Behavior Statistics and Protective Habits
Seat belt data combine modeled benefits, observed use and legal context. The CDC cites an NHTSA effectiveness model estimating that seat belts saved almost 15,000 U.S. lives in 2017. Facts About Seat Belt Use
Observed daytime seat belt use in 2022 was 92% in states with primary enforcement laws and 90% in states with secondary enforcement laws or no seat-belt law. These grouped figures describe observed use, not proof that enforcement law alone caused the difference.
As of September 2023, 29 states lacked a primary enforcement law covering all adult seating positions. The legal count is context for behavior, not a direct measure of whether an individual occupant buckled up.
| Location or group | Front-seat use | Rear-seat use | Period |
|---|---|---|---|
| United States | 87% | 78% | 2013 |
| Comparison-country range | 86% Austria to 99% France | 65% Austria to 97% Germany | 2013 |
| Comparison-country average | 94.1% | 82.1% | 2013 |
The CDC’s 2013 comparison used available observational data; methods were not identical across countries, and rear-seat data were unavailable for some countries. Vital Signs: Motor Vehicle Injury Prevention — United States and 19 Comparison Countries
Driver Attitudes and Youth Self-Reported Behavior Statistics
California’s 2022 statewide traffic-safety survey measures perception rather than crash causation or observed behavior. In that survey, 52.9% of respondents named driver behavior as the most important factor causing traffic injuries or fatalities, while 26.4% named speeding vehicles.
Other California attitude findings were similarly specific to the survey population and wording:
- 78.1% thought an impaired driver was very or somewhat likely to be arrested.
- 76.3% said marijuana can impair driving functions, 8.5% said it cannot and 15.2% said it depends.
- 50.0% called drug-impaired driving a very big problem, while 37.8% called it somewhat of a problem.
- 33.3% said it was safe to drive 10 mph over the freeway speed limit, 26.1% said no and 40.6% said it depends.
- 73.9% said it was not safe to drive over the speed limit on residential streets, compared with 9.4% who said yes and 16.7% who said it depends.
- 63.7% thought a speeding driver on residential streets was very or somewhat likely to receive a ticket; this combines the survey’s 23.6% very-likely and 40.1% somewhat-likely responses.
The residential-street question wording changed from the prior wave, limiting trend comparisons. California FY2022 Highway Safety Plan Annual Report
Youth data add a separate denominator warning. About 5% of U.S. high-school students who drove in 2023 reported driving after drinking alcohol in the previous 30 days, while about 16% of all high-school students reported riding with a driver who had been drinking. CDC Impaired Driving Facts
The first youth estimate uses students who drove as its denominator; the second uses all students. Both are YRBSS self-reports, so they should not be treated as direct observations of every young driver.
