In 2024, 39,254 Americans lost their lives due to traffic crashes. Yet road risk in the United States is much worse in some places than in others, with vulnerability to a potential crash varying dramatically depending on a person’s state.
This campaign sifts through key data to examine driving safety across all 50 states, ranking America’s best and worst drivers based on fatal crash rates and overall traffic fatalities.
Let’s begin by confirming which U.S. states feature the safest roads.
U.S. States: The Best vs. Worst Drivers Report Card
The above table reveals the 20 safest U.S. driving states, based on the composite ranking we built from crash rates, fatality rates, and driver behavioral issues.
By our measure, New Jersey ranks as the safest state. Though it doesn’t dominate any one category, it performed consistently well across all categories, ranking 6th safest for crashes, 5th for fatalities, 11th for speeding fatalities, and 2nd safest for drunk driving. Overall, it earns the lowest and best composite score of 6.0.
Massachusetts and Minnesota tied for second (11.3), followed by New York (13.3), Utah (14.8), Rhode Island (15.5), Maryland (15.8), New Hampshire (17.8), Pennsylvania (18.8), and Florida (19.5). Tenth-placed Florida is a notable inclusion, as its middling crash and fatality rates are offset by the lowest speeding fatality rate in the country.
Six of the ‘safe’ top 10 are Northeastern states, reinforcing the region’s consistently strong performance across multiple safety measures.
At the dangerous end of the rankings, Montana is the nation’s most dangerous state in which to drive. It posts a composite score of 46.5 after placing 45th for crash rate, 45th for fatality rate, 49th for speeding fatalities, and 47th for drunk driving fatalities. South Carolina (46.25), Wyoming (44.75), Oklahoma (41.75), Arizona (41.25), New Mexico (41.0), Texas (39.25), Alabama (37.0), North Carolina (34.75), and Nevada (33.25) complete the bottom 10.
The gap between New Jersey’s score of 6.0 and Montana’s score of 46.5 represents a 40.5-point gulf, while Connecticut (24.25) sits at almost exactly the national midpoint. The lower end of the rankings disproportionately features states from the South, Southwest, and Mountain West. No Northeastern state appears near the bottom of the list.
Only with a composite index score can we thoroughly define danger states. Montana, South Carolina, Wyoming, Oklahoma, New Mexico, and Alabama are among the worst crash-rate states and are in the overall bottom 10.
Yet Arizona, Texas, North Carolina, and Nevada take their places in the bottom tier mainly due to poor speeding and alcohol fatality rankings as opposed to unusually high crash or overall fatality rates. Only by combining multiple categories can we derive a full picture.
Similarly, despite ranking worst for both crash and fatality rates, Mississippi is ranked 33rd overall: the state also features the 4th-lowest speeding fatality rate and the 4th-lowest alcohol fatality rate. Arkansas, Louisiana, and Tennessee also avoid the composite ranking bottom 10 due to comparatively strong behavioral scores.
Ultimately, the report shows that the states with the worst crash fatality rates are not always the states with the riskiest driver behavior. Other relevant factors are in play, and by combining those with crash data, we’ve compiled a more complete picture of U.S. road danger.
Let’s now consider the contributory factors to the overall ranking in isolation, starting with the states featuring the highest per capita risk of fatal crashes.
The Riskiest Roads In The United States
If we measure 2024’s fatal crash numbers against each state’s Census Bureau population (rather than referencing raw numbers), we discover a very specific picture of American road safety. The 36,297 fatal crashes occurred among a population of just over 340 million: that equates to 10.7 fatal crashes per 100,000 residents.
Fatal crashes also follow clear seasonal trends, reaching their lowest levels in January (2,538) and February (2,498), then steadily climbing to an October peak (3,369), with August (3,342) and September (3,277) not too far behind. This data tells us that late summer travel and the abrupt shift into longer autumn nights coincide with the year’s highest crash activity.
This also partially confirms the oft-cited ‘100 Deadliest Days’ period between Memorial Day and Labor Day, when increased vacation travel, inexperienced teen drivers, unfamiliar roads navigated by out-of-town visitors, and a spike in alcohol-related social events are linked to high crash rates.
Per capita, the fatal crash burden predominantly falls on the South, Mountain West, and parts of Appalachia. Mississippi is the leading state by a significant margin: its 678 fatal crashes among 2.94 million residents (23.04 per 100,000 people) is more than double the national average and over four times the rates seen in Rhode Island (4.32), Massachusetts (4.89), and New York (5.21).
New Mexico (17.74), Arkansas (17.71), Wyoming (17.36), Alabama (17.35), South Carolina (17.30), Montana (16.97), Louisiana (15.33), Tennessee (15.12), and Oklahoma (14.50) complete the list of ten most afflicted fatal crash states. Combined, these ten states feature only 12% of the U.S. population, yet represent a significantly disproportionate share of fatal crash risk.
Raw crash totals tell a different story. Although Texas (3,774 crashes) and California (3,583) account for roughly a fifth of all U.S. fatal crashes, their large populations produce respective per capita rates of just 12.06 and 9.09 per 100,000, putting them well outside the group of highest-risk states.
At the opposite end of the spectrum, the District of Columbia recorded only 46 fatal crashes; ultimately, raw totals don’t show relative risk.
This contrast (between raw fatality counts and per capita rates) is central to our analysis. The greatest individual risk isn’t faced by drivers in the country’s largest states, but by those navigating the roads of mid-sized, rural, and Southern states.
We’ve looked at fatal crash data, but what about fatalities from crashes?
The Fatalities Behind The Crashes
While the previous section focused on the frequency of fatal crashes, crashes may claim multiple victims.
In the U.S. in 2024, 39,254 people died in 36,297 fatal crashes, at an average of 1.08 fatalities per crash. Against a national population of 340.1 million, the national fatality rate was 11.5 deaths per 100,000 residents.
As with fatal crash rates, Mississippi again ranked highest, recording 753 fatalities from a population of 2,943,045 (25.59 per 100,000), more than double the national average. Its 1.11 fatality-to-crash ratio was well above the national norm, suggesting that fatal crashes in Mississippi are disproportionately likely to involve multiple fatalities.
Arkansas ranked second (19.53 per 100,000), followed by New Mexico (19.20), South Carolina (18.95), and Alabama (18.65). The presence of Wyoming (18.21) and Montana (18.11) on the list reinforces the trend of sparsely populated states suffering disproportionately high fatality rates despite relatively low crash totals. Tennessee (16.56), Louisiana (16.35), and Arizona (16.21) complete the top ten.
Arizona, which doesn’t rank in the top ten for crashes, is a notable presence on the list. Its 1.10 fatality-to-crash ratio suggests severe crashes involving multiple victims. By contrast, Oklahoma, which ranked tenth for frequent crashes, doesn’t make the fatality top 10, proving that the number of crashes and the severity of crashes often misalign.
Seasonally, fatalities followed the same pattern as crashes. They rose from 2,710 in February to 3,620 in October, with August (3,611) and September (3,528) close behind, confirming late summer and early fall as the key danger periods on U.S. roads.
Raw totals again reflected scale rather than risk. Texas (4,160 fatalities) and California (3,876) represented roughly 20% of all U.S. traffic deaths. Despite this, their large populations kept their fatality rates at a relatively moderate level (13.30 and 9.83 per 100,000), with fatality-to-crash ratios close to the national average.
Overall, a look at fatality numbers augments the fatal crash picture: America’s highest per-capita road death burden falls on many Southern, rural, and mid-sized states, where crashes occur more frequently and are often more likely to involve fatalities.
Safe States
As we’ve discovered, population density doesn’t equal road danger. Massachusetts, despite featuring 7.1 million residents, recorded just 5.09 deaths per 100,000 in 2024, while New York (with nearly 19.9 million residents) posted a rate of just 5.54, the nation’s third-lowest rate.
These figures suggest dense, high-traffic states can feature comparatively safe roads due to their strong infrastructure, effective enforcement, and extensive public transport.
The Causes of Road Crashes
We’ve looked at where crashes happen, and how often. It’s also worth asking why crashes happen, which primarily comes down to three major behavioral factors: speeding, alcohol impairment, and driver distraction.
Nationally, speeding was a factor in 10,203 of 2024’s 36,297 fatal crashes (28.1%), meaning it was one of two leading causes of fatal collisions. In 25 of 50 states (and the District of Columbia), over 30% of fatal crashes involved speeding. Clearly, speeding is a nationwide issue as opposed to a niche problem.
Alcohol impairment (a driver with a blood alcohol concentration of 0.08% or higher) was a factor in 29.8% of fatal crashes, roughly on par with speeding as the country’s main behavioral crash risk. (Distraction also accounted for 8.2% of fatal crashes, although these figures are hard to accurately define as distraction is often difficult to confirm and experts suggest that the real percentage is likely to be much higher.)
Vermont was the only state to rank in the top 10 for both speeding and alcohol impairment. 50.9% of its 53 fatal crashes involved speeding, while 43.4% involved alcohol (the highest impairment rate in the United States). Alaska ranked second for speeding (47.6%), while Montana was prominently ranked for both speeding (43%) and alcohol impairment (35.8%), continuing the trend of disproportionate risk in sparsely populated states. Hawaii and Wyoming both recorded 41.2% for fatal crashes involving speeding.
Texas featured a high rate of drunk driver crashes (39.8%, 1,503 of 3,774 crashes), as did South Carolina (39.7%, 376 of 948 crashes); in both cases, this confirms that alcohol-related fatalities are not limited to smaller states. Ohio (36.2%), Kansas and Oklahoma (both 35%), and Iowa (34.9%) were also prominently ranked.
At the safer end of the spectrum, Florida featured the nation’s lowest speeding rate (10.7%). New Jersey recorded the lowest alcohol impairment rate (21.8%), while North Carolina featured the lowest distraction rate (1.4%) despite ranking sixth for speeding.
Perhaps most notable of all are the states that don’t rank highly. Despite topping the fatal crash and fatality rankings, Mississippi ranks outside the top 10 when it comes to all three driver crash behaviors: its rates of 17.3% for speeding, 22.7% for alcohol impairment, and 2.5% for distraction are all below national averages. That suggests an elevated crash risk due to other factors such as road infrastructure, emergency response times, a failure to use seat belts, or old vehicles in need of repair or replacement.
As touched upon earlier, distraction data is difficult to interpret. Hawaii (38.1%) and New Mexico (37%) top the distraction rankings, while states like North Carolina (1.4%) report particularly low figures. Such wide variation is unlikely to definitively reflect real behavioral differences. Instead, it suggests inconsistent reporting practices.
Overall, the data makes it clear that speeding and alcohol impairment are the two main behavioral contributors to fatal crashes in the U.S., with each a factor in around three in ten fatal collisions. It also confirms that the states that feature the highest crash and fatality rates are not necessarily those that feature the highest levels of behavioral risk.
And when we consider behavioral risk, as the following data confirms, the risk changes depending on a driver’s age.
Fatal Crash Involvement by Age
According to 2024 data, the drivers most involved in fatal crashes were 25-34 year-olds. This age group represented 6,921 fatalities (17.6%), followed by 35-44 year-olds (6,252, 15.9%), meaning people in their twenties and thirties made up around a third of all traffic deaths. Notably, adults aged 55 and older also accounted for a third of fatalities, with combined figures for drivers aged 55-64 (13.4%), 65-74 (10.5%), and 75+ (9.9%) closely matching the 33.5% of fatal crash fatalities 25-44 year-old drivers represent.
Despite similar fatality shares, the behavioral profiles of the two combined groups differ significantly. Older adults are less likely to be involved in speeding or alcohol impaired fatal crashes; this suggests that their elevated fatality burden is instead due to their comparative physical vulnerability in crashes as opposed to risky driving habits.
The clearest pattern emerges when we examine speeding data. 47.4% of fatalities involving 16-20 year-olds were due to speeding (the highest proportion of any age group). For 21-24 year-olds, the rate was also high at 42.2%. There’s then a steady decline in fatal speeding crashes as drivers age: 36.5% for 25-34 year-olds, 29.9% for 35-44 year-olds, 26.2% for 45-54 year-olds, 19.6% for 55-64 year-olds, 17.1% for 65-74 year-olds and just 14.1% for those aged 75 and older.
The proportion of fatal crashes due to alcohol impairment follows a different age-group pattern. The share rises from 22% for under 16s to 31% for 16-20 year-olds, then rises again to 41% for both 21-24 year-olds and 25-34 year-olds before steadily falling for each successive age group to 35%, 32%, 26%, 19% and finally 12% for the over 75s. Overall, the data tells us that teenagers are the group most heavily associated with speeding, with drivers in their early twenties most associated with drunk driving.
Fatal crashes due to distraction is at its highest among under-16s (11.4%) before falling to around the 7-8% range through subsequent age groups. It then rises modestly to 9% among 65-74 year-olds and again to 9.3% among drivers aged 75+.
Raw totals highlight scale: Texas recorded the highest fatalities among both 16-20 year-olds (385) and 25-34 year-olds (812), with California close behind (306 and 787), yet these numbers largely reflect population size.
Clearly, speeding is predominantly an issue that involves young drivers, with alcohol impairment most affecting young adults, and both behaviors steadily decreasing as drivers age. Older adults remain heavily represented in fatality totals, mainly due to their greater physical vulnerability, while distraction continues to be the most difficult behavioral factor to truly measure.
Florida Counties
Although Florida ranks among the nation’s safest driving jurisdictions (tenth overall on the composite index and lowest in the country for speeding-related fatalities), the state nonetheless features significant variation.
In 2024, Palm Beach County recorded 191 fatal crashes and 214 fatalities, a ratio of 1.12 fatalities per crash, compared with Hillsborough County’s 174 crashes, 181 fatalities, and a much smaller 1.04 ratio. It’s the ratio, not the raw total, that tells the real story: a figure above 1.0 means more than one person died, on average, in every fatal crash recorded, a marker of severity rather than frequency.
Palm Beach’s 1.12 significantly exceeded the national average of 1.08, along with the rates recorded in Miami-Dade (1.05), Broward (1.06), and Orange County (1.04), making it a clear outlier among Florida’s most populous counties.
The contrast is notable precisely because all four counties operate under the same statewide enforcement priorities and the same overall safety ranking. Whatever the reasons for Palm Beach’s elevated rate (high-speed corridors, dense seasonal tourist traffic, longer average trip distances, or an older driver population more physically vulnerable in a crash), a statewide average was never going to make it clear.
This offers a microcosm of the report’s central lesson: just as national totals don’t reveal which states carry the greatest road risk, a state’s own average doesn’t reveal which of its counties carry the highest levels of risk. Even in a relatively safe driving state, it’s important to emphasize the fact that not all areas are the same, and that some state counties may be anomalously dangerous.
Raw Total Fatality Numbers: No Reliable Measure of U.S. Road Danger
Calibrating 2024 fatal crash data so it accounts for population levels reveals a more nuanced picture of U.S. road safety than raw totals alone.
While the national average was 10.7 fatal crashes per 100,000 residents, Mississippi recorded the highest rate (23.04), followed by nine other states including New Mexico, Arkansas, and Wyoming. Despite accounting for only around 12% of the U.S. population, these states carried a disproportionate share of fatal crash risk. By contrast, Texas and California recorded the most fatal crashes overall but ranked far lower per capita.
It was a similar pattern for fatalities. Nationally, 39,254 people died in 36,297 fatal crashes, averaging 1.08 deaths per crash. Mississippi again recorded the highest fatality rate (25.59 per 100,000), while Rhode Island, Massachusetts, and New York were the safest states with the lowest rates. Arizona took a place in the top 10 due to a high crash severity (despite lower crash frequency).
The greatest individual risk isn’t faced by drivers in the country‘s largest states, but by those navigating the roads of mid–sized, rural, and Southern states
Behaviorally, speeding (28.1%) and alcohol impairment (29.8%) were the leading contributors to fatal crashes. Vermont, Montana, and Alaska ranked highest for speeding; Vermont, Texas, and South Carolina led for drunk drivers. Mississippi, however, ranked below average for speeding, impairment, and distraction despite its high fatality burden.
This suggests other factors were in play, such as infrastructure, emergency response, or vehicle age and condition. Distraction data varied widely between states, indicating inconsistent reporting.
Age patterns showed speeding concentrated among teenagers, alcohol impairment peaking in drivers aged 21-34, and both behaviors declining steadily with age. Older adults, despite accounting for a similar share of fatalities as younger adults, were more vulnerable because of age as opposed to risky driving.
Combining crash rates, fatalities, speeding, and alcohol impairment into a composite index ranked New Jersey as the safest state overall and Montana the most dangerous.
The index demonstrated that poor road safety is not always driven by risky behavior alone, with states like Mississippi performing well on behavioral measures despite high crash and fatality rates.
Ultimately, road safety on American roads is often less clear than simple, raw totals can make it appear. By delivering a more nuanced look at the issues across all U.S. states, we’ve provided a potentially useful resource to those responsible for making road infrastructure improvements, adjusting enforcement efforts, and targeting funding and campaigning. Nearly 40,000 annual deaths on state roads, many due to driver behavior, is far too many.
Every few seconds, there’s a vehicle or bike crash on American roads. Unfortunately, in many of these accidents, people suffer severe bodily injuries and property damage. This leads to costly medical bills, pain and suffering, lost income, and rental car expenses.
