Key Takeaways
- 40,901 deaths in 2023. That is the total number of people killed in motor-vehicle crashes on US roads in 2023, the latest year of final federal data. It works out to 12.2 deaths per 100,000 people.
- Texas has the most. Texas recorded 4,291 traffic deaths in 2023, the highest of any state, followed by California (4,061) and Florida (3,396). The biggest states top the list because they have the most drivers and miles driven.
- Mississippi has the deadliest roads. Adjusted for population, Mississippi (24.9 deaths per 100,000) and Wyoming (24.7) have the highest fatality rates, roughly five times safer Massachusetts (4.9).
- Deaths are falling again. US road deaths peaked at about 42,900 in 2021. They have dropped every year since, and NHTSA projects around 39,345 deaths for 2024.
- Most crashes are preventable. Speeding, impaired driving, distraction and unbelted occupants drive the majority of fatal crashes nationwide.
Car accidents are one of the leading causes of death in the United States, and the toll varies enormously from one state to the next. In 2023, the most recent year of final federal data, 40,901 people died in motor-vehicle crashes on American roads, according to the National Highway Traffic Safety Administration’s Fatality Analysis Reporting System (FARS). That is about 12.2 deaths for every 100,000 people, or 1.26 deaths per 100 million miles driven.
So which states have the most car accidents? The map below shows total traffic deaths by state for 2023. As you would expect, the biggest, busiest states sit at the top, because more people and more miles driven mean more crashes overall.
Which states have the most car accidents?
Ranked by the raw number of automobile accident deaths, the same handful of large states lead the country year after year. Here are the 15 states with the most traffic fatalities in 2023.
🤠 Texas
Texas has the most car accident deaths of any US state, with 4,291 fatalities in 2023. The Lone Star State combines a huge population with vast distances and heavy rural driving, a mix that keeps its crash totals at the top of the list. Its rate of 14.1 deaths per 100,000 people is close to the national average, so the headline number is driven mostly by sheer size.
🌴 California
California is a close second with 4,061 deaths. It is the most populous state in the country, yet its fatality rate of just 10.4 per 100,000 is well below the national average, helped by dense urban driving and strong traffic-safety laws.
🏖️ Florida
Florida ranks third with 3,396 traffic deaths. The state’s millions of tourists, year-round driving weather and high share of pedestrian and motorcycle deaths push its total well above its population rank, at 15.0 deaths per 100,000.
🍑 Georgia
Georgia recorded 1,615 deaths in 2023, fourth nationally. Rapid population growth around Atlanta and busy interstate corridors keep its numbers high, with a rate of 14.6 per 100,000.
⛰️ North Carolina
North Carolina rounds out the top five with 1,561 deaths (14.4 per 100,000). A mix of mountain roads, coastal traffic and growing metro areas around Charlotte and Raleigh contributes to the toll.
The deadliest roads: car accident deaths per capita
Total deaths reward big states. To find where driving is actually most dangerous, you have to adjust for population. On that measure the ranking flips toward smaller, more rural states:
- Mississippi: 24.9 deaths per 100,000 people, the highest in the nation
- Wyoming: 24.7 per 100,000
- New Mexico: 20.7 per 100,000
- South Carolina: 19.5 per 100,000
- Arkansas: 19.4 per 100,000
- Alabama: 19.1 per 100,000
At the other end, Massachusetts is the safest state to drive, with just 4.9 deaths per 100,000 people, followed by other densely populated Northeastern states. Rural states tend to have higher rates because crashes happen at higher speeds, seat-belt use is often lower, and emergency medical help can be farther away.
What is driving the numbers?
While every state is different, the same factors show up in fatal crashes everywhere. Most are preventable:
- Speeding is a factor in roughly a third of all traffic deaths.
- Impaired driving (alcohol or drugs) accounts for a large share of fatalities, especially at night and on weekends.
- Distracted driving, above all texting, continues to rise with smartphone use.
- Unbelted occupants: nearly half of people killed in crashes were not wearing a seat belt.
Are US roads getting safer?
After a sharp jump during the pandemic, the trend has finally turned. US traffic deaths peaked at about 42,900 in 2021, then fell to roughly 42,700 in 2022 and 40,901 in 2023. NHTSA’s early estimate puts 2024 lower still, at around 39,345 deaths, a 3.8% decline. Better vehicle safety technology, automatic emergency braking and renewed enforcement are all helping, even as total miles driven have climbed back above pre-pandemic levels.
The bottom line
If you measure by total automobile accidents, Texas, California and Florida lead the country, simply because that is where the most people and the most driving are. But the deadliest roads per driver are in Mississippi, Wyoming and other rural states. The encouraging news is that, nationwide, US roads are slowly getting safer again after the 2021 spike, and most of the crashes behind these numbers are preventable.
