Mississippi Just Topped the List of America’s Most Dangerous States to Drive In

Pulling out of your own driveway carries very different odds depending on which state you call home. A new analysis of federal crash data just crowned Mississippi the most dangerous state for drivers in the country, based on fatal crashes per 100,000 residents. Wyoming and New Mexico followed close behind in second and third place. Where you live, it turns out, may say more about your driving risk than how carefully you actually drive.

Here’s Exactly How Researchers Built This Ranking

Online tire retailer Priority Tire built these rankings using National Highway Traffic Safety Administration data on fatal crashes from 2023, the most recent year available. Researchers divided each state’s total fatal crashes by its population to calculate a rate per 100,000 residents, rather than simply ranking states by raw crash totals. That distinction matters, since larger states naturally rack up more crashes overall.

Mississippi’s Rate Is More Than Double the National Average

Mississippi’s numbers stand out even against a rough national backdrop. The nationwide rate sat at 9.6 fatal crashes per 100,000 people in 2023. Mississippi’s rate of 24.9 came in at more than double that national average, based on 732 total fatal crashes recorded during the year. Wyoming trailed closely behind at a rate of 24.7, despite recording far fewer total crashes at 144.

Seven More States Round Out America’s Most Dangerous Top Ten

Rounding out the ten most dangerous states, New Mexico ranked third at a rate of 20.7, followed by South Carolina at 19.5 and Arkansas at 19.4. Alabama, Tennessee, Montana, Kentucky, and Louisiana filled out the remainder of the top ten, with rates ranging from 19.1 down to 17.7 fatal crashes per 100,000 residents in each state.

Some Top-10 States Are Getting Worse, Others Are Improving

Year-over-year trends varied considerably even among states near the top of the list. Mississippi’s fatal crash total rose 4 percent from 703 in 2022 to 732 in 2023, while Wyoming’s climbed 7 percent. New Mexico moved in the opposite direction entirely, with crashes falling 6 percent from 466 to 437. South Carolina declined 4 percent, and Arkansas dropped 6 percent over the same period.

Rural Roads Are the Common Thread, Says the Study’s Author

Priority Tire’s president pointed to rural road conditions as a likely factor behind the pattern. “Rural roads may contribute to higher fatal crash rates because they can have higher speed limits, less maintenance and longer distances to hospitals,” said Dimitri Chernyak. That combination, higher speeds paired with slower emergency response times, shows up repeatedly among the states topping this particular ranking.

Simple Habits Could Meaningfully Cut Your Personal Risk

Chernyak also offered direct, practical advice based on the findings. He recommended drivers wear seat belts consistently, take breaks during long trips when feeling tired, and keep their vehicles properly maintained, specifically calling out tire tread and tire pressure as easy checks that many drivers skip. Simple maintenance, he suggested, can meaningfully reduce a driver’s individual risk regardless of which state they live in.

Massachusetts Is the Safest State in the Country to Drive

Massachusetts landed at the opposite end of the rankings entirely, recording the lowest fatal crash rate in the country at just 4.9 per 100,000 residents. New York followed at 5.7, while Rhode Island, New Jersey, and Hawaii each posted a rate of 6.5. Every one of these states sits well below the 9.6 national average recorded for 2023.

Rhode Island Saw a Bigger Swing Than Any Top-10 State

Some of the sharpest year-over-year swings appeared far from the states topping the overall danger rankings. Rhode Island’s fatal crashes jumped 37 percent between 2022 and 2023, followed by a 28 percent increase in Idaho and a 12 percent rise in Iowa. Meanwhile, Alaska’s fatal crashes fell 27 percent, Hawaii’s dropped 20 percent, and Massachusetts posted a 21 percent decline.

One Detail Explains Why Rural States Dominate This List

One methodology detail matters for interpreting this entire ranking correctly. These figures measure fatal crashes relative to each state’s population, not the total number of crashes recorded. A more populous state can log more fatal crashes overall while still posting a lower rate once its larger population gets factored into the calculation, which is exactly why smaller, rural states dominate the top of this particular list.
