A new nationwide study by Shane Smith Law has identified Mississippi as the deadliest state when it comes to uninsured drivers involved in fatal crashes.
The findings, based on federal crash data and insurance statistics, show that states with higher uninsured populations face significantly greater risks on the road — both for drivers and for accident victims who may struggle to recover compensation.
Mississippi Ranks #1
Mississippi led the nation in 2023 with 69 uninsured drivers involved in fatal crashes. Adjusted for population, this equals 24 uninsured drivers per million residents — the highest rate of any state.
The state also ranks eighth for percentage of uninsured residents, with 10.3% of Mississippians lacking auto insurance coverage.
Wyoming and Texas Not Far Behind
Wyoming placed second, with 22 uninsured drivers involved in fatal crashes per million residents. The state recorded 13 such crashes in total, but its small population magnifies the rate. With 10.7% of residents uninsured, Wyoming ranks sixth overall for insurance gaps.
Texas finished third, with 21 uninsured drivers per million residents. More alarmingly, Texas recorded 635 uninsured drivers in fatal crashes — the highest raw number in the U.S. The state also leads the nation with the largest uninsured population percentage at 16.4%.
Oklahoma and New Mexico Tie for Fourth
Both Oklahoma and New Mexico reported 18 uninsured drivers in fatal crashes per million residents.
- Oklahoma has one of the highest uninsured populations (11.4%) and logged 73 fatal crashes involving uninsured drivers.
- New Mexico, with a 9.1% uninsured rate, recorded 37 such crashes in 2023.
The Five Most Dangerous States
| Rank | State | % Uninsured Residents | Fatal Crashes Involving Uninsured Drivers (per million residents) | Total Fatal Crash Drivers 2023 |
|---|---|---|---|---|
| 1 | Mississippi | 10.3% | 24 | 665 |
| 2 | Wyoming | 10.7% | 22 | 121 |
| 3 | Texas | 16.4% | 21 | 3,874 |
| 4 | Oklahoma | 11.4% | 18 | 643 |
| 5 | New Mexico | 9.1% | 18 | 402 |
States With the Lowest Rates
By contrast, Massachusetts had the lowest rate in the nation, with just 1 uninsured driver in fatal crashes per million residents. Only 2.6% of Massachusetts residents are uninsured, the lowest percentage in the U.S. Out of 325 drivers involved in fatal crashes statewide, just one was estimated to be uninsured.
Other states with the lowest rates include:
- Hawaii – 2 uninsured drivers per million residents (3.2% uninsured rate)
- New York – 3 uninsured drivers per million residents (4.8% uninsured rate)
- Minnesota – 3 uninsured drivers per million residents (4.2% uninsured rate)
- Rhode Island – 3 uninsured drivers per million residents (4.5% uninsured rate)
These states combine stronger insurance compliance with lower uninsured populations, helping keep both rates and raw numbers far below the national average.
Expert Commentary
A spokesperson from Shane Smith Law said:
“The data shows a clear relationship between states with high uninsured populations and fatal crashes involving uninsured drivers. This creates real challenges for victims and families who may not have access to the compensation they deserve.
States that enforce stricter insurance requirements consistently report fewer uninsured drivers and fewer deadly crashes. Expanding insurance mandates and improving compliance could save lives and protect drivers financially.”
Why It Matters
For accident victims, the involvement of an uninsured driver can complicate the recovery process. Without an active insurance policy, families may be forced to rely on their own uninsured motorist coverage — or face overwhelming medical costs and financial hardship.
The Shane Smith Law study highlights the urgent need for policy reform and enforcement in states with high uninsured rates. By strengthening insurance requirements and ensuring better compliance, states could dramatically reduce the number of uninsured drivers on the road and, in turn, lower the risks of fatal crashes.
