NHTSA Car Crash Statistics on Speeding and Drunk Driving
National crash data shows how many people are killed on American roads each year and which driver behaviors are involved. Every figure below comes from the National Highway Traffic Safety Administration (NHTSA), and each one is tied to its data year. A car accident attorney might use numbers like these for context, but statistics describe patterns across many crashes rather than what happened in any one of them.
Total traffic deaths
According to NHTSA, 39,254 people died in traffic crashes in 2024, for a rate of 1.19 per 100 million vehicle miles traveled. The agency's early estimate for 2025 was 36,640 deaths, a 6.7 percent decrease from 2024, and a rate of 1.10 per 100 million vehicle miles traveled. Early estimates change once each year's data is finalized, so the 2025 number may move.
Speeding and impaired driving
According to NHTSA, 11,288 people died in speeding-related crashes in 2024, and speeding was a contributing factor in 29 percent of all traffic fatalities that year. The agency also reports that 11,904 people died in alcohol-impaired driving crashes in 2024, which the agency describes as one person every 44 minutes. Roughly 30 percent of all traffic fatalities involve drivers with a blood alcohol concentration (BAC) of .08 or higher. Lower levels can matter too. In 2024, 2,028 people were killed in alcohol-related crashes in which a driver had a BAC of .01 to .07. Every state except Utah, which uses .05, sets the limit at a BAC of .08.
Distraction and fatigue
NHTSA reports that 3,208 people were killed in crashes involving distracted drivers in 2024. The agency notes that sending or reading a text takes a driver's eyes off the road for 5 seconds, roughly the length of a football field at 55 mph. Fatigue is harder to count. https://alexisrnma935.halcyonledger.com/posts/diminished-value-and-other-car-accident-insurance-issues-2 NHTSA estimates that in 2017, 91,000 police-reported crashes involved drowsy drivers, leading to about 50,000 injuries and nearly 800 deaths, and it says that figure is widely viewed as an underestimate.
Restraint use
NHTSA reports that 22,713 passenger vehicle occupants were killed in 2024, and nearly half of them, 48 percent, were unrestrained, based on known seat belt use. Seat belt use nationally stood at 91.3 percent in 2025. NHTSA estimates that seat belts saved 14,955 lives in 2017. In some states, not wearing a seat belt can be raised to reduce damages, while other states limit that defense. A car accident lawyer will know the rule where the crash happened.
How to read crash data
The categories overlap. One crash can fall into the speeding and alcohol categories at once, so the figures should not be added together. NHTSA's Fatality Analysis Reporting System (FARS) is a census of fatal crashes, and the Crash Report Sampling System (CRSS) is a sample of police-reported crashes. NHTSA's National Center for Statistics and Analysis publishes FARS data and the annual Traffic Safety Facts reports, while many states also publish their own crash data. These databases describe crashes but do not assign fault. A car accident attorney relies on each claim's own evidence, starting with the crash report and photos.
