Traffic deaths in the United States fell from their pandemic‑era peak, yet the risk of dying on the road still varies sharply by location. In 2024, the Insurance Institute for Highway Safety (IIHS) reported 39,254 motor‑vehicle crash deaths, equating to 11.5 deaths per 100,000 people and 1.19 deaths per 100 million vehicle miles traveled.
States with the Highest Fatality Rates per Mile
The Law Offices of Pius Joseph, a Pasadena personal‑injury firm, examined state‑level crash death rates using IIHS Fatality Facts data. Mississippi led the nation with 1.81 deaths per 100 million vehicle miles, also posting the highest population‑based rate at 25.6 deaths per 100,000 residents. Arizona ranked second (1.74), followed by South Carolina (1.67), Arkansas (1.53) and Tennessee (1.52).
States with the Lowest Rates
Massachusetts posted the lowest fatality rate per mile at 0.59, while Rhode Island had the lowest population‑based rate at 4.7 deaths per 100,000 people.
Total Deaths by State
Texas recorded the most total crash deaths in 2024 with 4,160 fatalities, followed by California (3,876) and Florida (3,138). However, none of these high‑population states appeared among the five deadliest on a per‑mile basis. Texas, California and Florida posted rates of 1.35, 1.19 and 1.26 deaths per 100 million vehicle miles respectively, compared with Mississippi’s 1.81.
Rural Versus Urban Crash Patterns
Nationwide, 16,006 of the 39,254 deaths (41%) occurred in rural areas. Rural fatalities comprised a majority of crash deaths in each of the five states highlighted for high per‑mile rates: Montana (79% of its deaths), Arkansas (68%), Mississippi (67%), Kentucky (62%) and West Virginia (56%). Rural roads often feature higher speeds, longer emergency‑response times, fewer divided highways, limited lighting and more two‑lane routes, all of which can increase crash severity.
Single‑Vehicle Crashes
Single‑vehicle crashes accounted for 52% of all 2024 fatalities, with several high‑risk states exceeding the national average. Mississippi (58%), Montana (60%), Arkansas (57%), West Virginia (57%) and Oregon (55%) all saw a majority of deaths in single‑vehicle incidents, which can involve run‑off‑road events, rollovers or collisions with fixed objects.
Speeding Involvement
Speeding was a factor in 29% of all crash deaths nationwide. The highest state percentages were Vermont (54%) and Alaska (50%). Among the states with the highest per‑mile death rates, speeding involvement varied: Arizona (36%), South Carolina (38%), Montana (43%) and Nevada (33%). Mississippi, despite its overall fatality leadership, reported speeding in only 17% of its crash deaths.
Vehicle‑Type Breakdown
Across the country, crash victims were 30% car occupants, 27% pickup or SUV occupants, 16% motorcyclists, 18% pedestrians and 3% bicyclists. Montana had the highest share of SUV and pickup deaths (47%), while South Carolina led in car‑occupant deaths (38%). Hawaii showed a relatively high proportion of pedestrian (34%), bicyclist (7%) and motorcyclist (25%) fatalities.
Key Takeaways
The data underscore that roadway safety remains uneven across the United States. No single factor—rural location, speeding, single‑vehicle crashes, or vehicle type—explains why some states have deadlier roads. Instead, a combination of roadway design, travel speeds, law enforcement, driver behavior, vehicle mix, emergency‑response capability and geography shapes risk. Drivers should remain vigilant, and policymakers may consider targeted safety measures that address the specific challenges identified in each high‑risk state.
