Road safety remains a major concern across the United States, with traffic deaths varying significantly by state, population, travel patterns, road design, and driver behavior. Comparing fatality figures since 2019 helps identify where the number of lives lost on American roads has increased and where policymakers may need stronger interventions.
A reliable ranking must use comparable annual data, distinguish actual fatalities from fatality rates, and account for changes over time. This article examines the states with the largest increases, explains the figures behind the comparison, and considers what the numbers mean for drivers, communities, and transportation officials.
1. Nevada: Traffic fatalities increased by 37.2%
Nevada ranks first in this comparison, with traffic fatalities rising from 304 in 2019 to 417 in 2024. That represents an increase of 113 deaths, or approximately 37.2%. The figures come from NHTSA’s state fatality tables and make Nevada the state with the largest percentage increase among the ten listed here.
The size of this increase deserves attention because Nevada’s starting figure was considerably smaller than those of states such as Texas and Arizona. A rise of 113 fatalities can represent a substantial percentage change in a state with a comparatively small annual total. This illustrates why percentage increases and raw numbers should be reported together.
Nevada has a distinctive transportation environment. Las Vegas is a major visitor destination, and the state also has long stretches of highway connecting communities across desert terrain. Urban congestion, high-speed roads, long travel distances, and the movement of visitors can create different road safety challenges. These characteristics provide useful context, but they do not establish why the state’s fatality count rose.
Determining the causes would require detailed crash records showing where deaths occurred, which road users were involved, and whether speeding, impairment, distraction, or other factors contributed. Researchers would also need to compare vehicle miles traveled over the same period. A larger number of deaths does not necessarily mean that the risk per mile increased by the same percentage.
For Nevada, the practical priority is to identify the locations and circumstances responsible for the increase. Road engineering, speed management, impaired-driving enforcement, pedestrian protection, and consistent seat belt use can all form part of a safety strategy.
The statistics establish the scale of the change, while detailed investigations can help determine which interventions are most likely to prevent future deaths.
2. Washington: Fatalities increased by 35.7%
Washington recorded 538 traffic fatalities in 2019 and 730 in 2024, an increase of 192 deaths. That equals approximately 35.7%, placing the state second in this ranking. The figures show that the annual death toll was considerably higher in 2024 than in the year used as the baseline.
The increase is significant because Washington contains a mix of dense urban areas, suburban commuting routes, mountain highways, rural roads, and coastal communities. Traffic conditions vary considerably between the Seattle metropolitan area and less densely populated parts of the state. Safety measures therefore need to reflect local conditions rather than rely on a single statewide solution.
Weather and road conditions are also relevant considerations for investigators. Rain, reduced visibility, darkness, and winter conditions can affect driving, while road geometry and vehicle speeds influence the consequences of a collision. These are potential risk factors that warrant examination, not proven explanations for Washington’s change in fatalities.
A proper assessment should compare fatal crashes by county, road type, time of day, and type of road user. It should also measure pedestrian and cyclist deaths separately from vehicle occupant deaths. Such a breakdown can reveal whether the increase is concentrated on particular corridors or spread across different travel environments.
Washington’s data highlights the importance of reducing fatal crashes through evidence-based road design, effective speed management, safer pedestrian crossings, responsible driving, and focused enforcement. Progress should be measured by tracking both the annual number of traffic fatalities and fatality rates adjusted for the amount of travel.
That approach helps officials distinguish changes in traffic volume from changes in the danger faced by each road user.
3. New Hampshire: Fatalities increased by 31.7%
New Hampshire recorded 101 traffic fatalities in 2019 and 133 in 2024. The increase of 32 deaths translates to approximately 31.7%, the third-largest percentage rise among the ten states listed. While its absolute increase is smaller than those recorded in several larger states, the change is substantial relative to its baseline.
Smaller annual totals can fluctuate considerably from year to year. A relatively limited number of additional deaths may produce a large percentage increase, which is why these results should not be interpreted without context.
The 31.7% change accurately describes the comparison between the two years, but it does not establish a consistent upward trend throughout the entire period.
New Hampshire’s roads include local streets, rural highways, interstate routes, and roads used by seasonal visitors. Different conditions can affect each setting. Curves, limited lighting, changing weather, and interactions between local and through traffic are all issues that road safety assessments may consider when reviewing serious crashes.
To understand the rise, analysts would need to examine fatal crash locations, the number of miles driven, driver behavior, vehicle types, and the ages and travel modes of those killed. They should also compare several consecutive years, since an unusually low or high starting year can affect the apparent percentage change.
The most useful response is a focused review of high-risk roads and crash circumstances. Improvements may include clearer road markings, safer intersections, better nighttime visibility, appropriate speed limits, and measures to reduce impaired driving.
For a smaller state, careful analysis of individual fatal crashes can be particularly valuable because each incident has a meaningful effect on the annual total.
4. Minnesota: Fatalities increased by 31.0%
Minnesota’s traffic fatality count rose from 364 in 2019 to 477 in 2024. That is an increase of 113 deaths, equivalent to approximately 31.0%. The change places Minnesota fourth in this ranking and shows that its 2024 total was significantly higher than its 2019 figure.
The state’s road network includes busy metropolitan routes around Minneapolis and Saint Paul, intercity highways, and rural roads serving agricultural and smaller communities.
These environments create different safety demands. Congestion and intersections can be important in urban areas, while high speeds, long journeys, and limited lighting can be relevant on rural routes.
Minnesota also experiences seasonal weather changes that can affect visibility, traction, and stopping distances. Ice and snow are legitimate road safety concerns, but it would be inaccurate to attribute the full increase in fatalities to winter weather without evidence from crash reports. A sound explanation must account for the actual conditions surrounding each collision.
A detailed review should identify whether deaths increased among vehicle occupants, pedestrians, motorcyclists, or cyclists. Investigators should also assess restraint use, impairment, speed, road design, and the time and location of crashes.
Comparing these findings with travel volume would help establish whether particular risks became more common or more severe.
Minnesota can use this evidence to direct investment toward the roads and behaviors most strongly associated with fatal outcomes. Measures might include safer rural intersections, speed control, improved pedestrian crossings, timely winter maintenance, and stronger seat belt compliance. Consistent monitoring would help determine whether these actions reduce deaths in subsequent years.
5. Arizona: Fatalities increased by 25.5%
Arizona recorded 979 traffic fatalities in 2019 and 1,229 in 2024. The difference is 250 deaths, an increase of approximately 25.5%. This places Arizona fifth in the ranking and gives it the second-largest absolute increase among the ten states, behind Texas.
Arizona’s population centers, including the Phoenix and Tucson metropolitan areas, rely heavily on road travel. The state also has extensive highways connecting communities over long distances.
Traffic volume, commuting patterns, tourism, freight movement, and the design of high-speed roads are useful subjects for safety analysis, but none should be treated as a confirmed cause without supporting data.
Hot weather creates specific vehicle and road maintenance challenges, while long stretches of highway can encourage sustained high speeds. Urban areas present different risks, including busy intersections and interactions among drivers, pedestrians, cyclists, and motorcyclists. These varied conditions make location-specific crash analysis more informative than a single statewide explanation.
The increase of 250 deaths is large enough to justify a close examination of where fatal crashes occurred and which circumstances were most common.
Authorities could assess speed-related crashes, impaired driving, intersection collisions, motorcycle fatalities, and pedestrian deaths. Comparing annual traffic exposure would also help clarify whether the change reflects more driving, greater risk per mile, or a combination of factors.
Practical responses may include safer intersection layouts, pedestrian refuge areas, speed management, public awareness campaigns, and targeted enforcement against dangerous driving.
Highway design should account for the consequences of human error, not simply assume every driver will behave perfectly. Arizona’s figures underline the importance of using reliable local evidence to decide where safety funding can have the greatest effect.
6. New Jersey: Fatalities increased by 20.1%
New Jersey’s traffic fatalities increased from 558 in 2019 to 670 in 2024. That is an increase of 112 deaths, or approximately 20.1%. The state ranks sixth by percentage change in this comparison. Its figures demonstrate that a state with a dense road network can experience a meaningful increase even when its annual total remains below that of larger states.
New Jersey has heavily traveled commuter routes, major interstate connections, urban streets, suburban roads, and busy commercial corridors. These networks carry passenger vehicles, delivery vans, trucks, buses, and other road users.
The number of road interactions can make intersection design, lane changes, merging, and pedestrian access important subjects for local safety reviews.
Dense development can also mean that motorists, pedestrians, cyclists, and public transportation users share limited space. Road layouts that prioritize vehicle movement without adequate pedestrian protection may create additional risks at crossings and intersections. However, the statewide fatality figures alone cannot establish whether such conditions contributed to New Jersey’s increase.
To investigate the change, transportation officials should compare fatal crash records across counties and road categories. They should examine whether deaths increased on high-speed highways, local streets, or particular intersections, while also assessing impairment, speeding, restraint use, and pedestrian involvement. Traffic volume and the number of miles traveled would help provide a fair comparison between 2019 and 2024.
New Jersey’s response can combine road engineering with enforcement and public education. Potential measures include safer pedestrian crossings, improved intersection visibility, better speed management, and protections for vulnerable road users.
Regular publication of detailed crash data would help residents understand the risks near their communities and allow officials to evaluate which measures are producing measurable improvements.
7. New York: Fatalities increased by 17.9%
New York recorded 934 traffic fatalities in 2019 and 1,101 in 2024, an increase of 167 deaths. The percentage increase is approximately 17.9%, placing New York seventh in the ranking. These figures refer to the state of New York, not New York City alone.
The state has a varied transportation system that includes New York City’s dense street network, suburban commuter roads, upstate highways, rural routes, and roads serving tourist destinations.
The risks on these networks are not identical. Urban safety planning must account for pedestrians and cyclists, while rural and highway planning must also consider vehicle speeds, visibility, and road geometry.
The distinction between statewide and city-level statistics matters when interpreting the data. A rise in the statewide total could reflect changes in several regions, and the state figures do not identify which counties or municipalities experienced the largest increases. Assigning responsibility to a particular city or road would require more detailed records.
A useful investigation would separate fatalities by road user and location, then examine factors such as speeding, impairment, nighttime crashes, intersection design, and seat belt use.
Analysts should also compare the number of trips and vehicle miles traveled. Those measures help establish whether the increase in deaths occurred alongside increased travel or a higher fatality risk per mile.
New York can direct safety improvements toward locations where serious crashes repeatedly occur. Safer crossings, protected cycling infrastructure where appropriate, clearer road markings, effective speed limits, and improved intersection design can reduce the likelihood that a driving error becomes fatal.
The state’s annual totals provide a reason to investigate further, while local evidence should determine which projects receive priority.
8. Colorado: Fatalities increased by 15.4%
Colorado’s traffic fatalities rose from 597 in 2019 to 689 in 2024. This represents an increase of 92 deaths, or approximately 15.4%. Colorado ranks eighth among the ten states selected for this comparison. The figures show a higher fatality count in 2024, but they do not by themselves reveal which road conditions or behaviors account for the change.
Colorado’s transportation network includes the Denver metropolitan area, expanding suburban communities, mountain passes, rural highways, and roads used by visitors traveling to outdoor recreation areas.
These settings require different approaches to safety. Urban traffic brings frequent interactions between road users, while mountain routes can involve sharp curves, elevation changes, and weather that changes quickly.
Mountain roads and winter driving are important considerations for Colorado, but it would be misleading to assume they explain the statewide increase.
A reliable assessment needs crash-specific evidence, including whether a collision involved excessive speed, impairment, poor visibility, road design, or another contributing factor. It also needs to distinguish fatal crashes on local roads from those on major highways.
The state can examine its fatal crashes by county, roadway, vehicle type, and road user. Comparing the 2019 and 2024 figures with annual travel exposure would provide additional context.
If deaths increased on particular corridors, engineers could investigate road geometry, barriers, intersections, signs, and speed limits. If the increase involved particular driving behaviors, targeted enforcement and education may be appropriate.
9. Texas: Fatalities increased by 14.9%
Texas recorded 3,619 traffic fatalities in 2019 and 4,160 in 2024, an increase of 541 deaths. This equals approximately 14.9%, ranking Texas ninth by percentage change. In absolute terms, however, Texas experienced the largest increase among the ten states in this article.
The difference between percentage growth and the number of deaths is especially important in Texas. Because the state’s annual fatality count is already high, a moderate percentage increase can translate into hundreds of additional lives lost. This is why a responsible comparison should present both measures rather than relying exclusively on percentages.
Texas has a large road network connecting major metropolitan areas, smaller towns, industrial centers, and rural communities. Interstate highways carry substantial passenger and commercial traffic, while local roads serve daily commutes and neighborhood travel.
Long distances and high-speed routes make roadway design, speed management, and safe vehicle operation important topics for transportation planning.
The statewide numbers cannot establish whether population growth, increased driving, speeding, impaired driving, or other factors caused the additional deaths.
Each possibility requires evidence. A complete analysis would compare annual vehicle miles traveled, examine the locations of fatal crashes, and assess the roles of different road users, vehicle types, and contributing behaviors.
10. North Carolina: Fatalities increased by 11.1%
North Carolina recorded 1,457 traffic fatalities in 2019 and 1,619 in 2024. The increase of 162 deaths amounts to approximately 11.1%, placing the state tenth among the states in this ranking. Although its percentage increase is lower than that of the other nine states listed, its additional fatalities represent a significant public safety concern.
North Carolina has major metropolitan areas, growing suburbs, rural communities, and extensive highway connections. These different environments bring distinct challenges, from congestion and busy intersections to high-speed rural roads.
Population distribution, travel demand, road design, and the types of vehicles using a corridor all matter when examining serious crashes.
The increase should not be assigned to a particular cause without supporting evidence. Factors such as speeding, impairment, distraction, restraint use, and pedestrian safety can be investigated through crash records. Changes in travel volume should also be considered because a greater number of miles driven can affect the number of collisions, even when the risk per mile changes less dramatically.
Transportation officials can compare fatal crash locations between 2019 and 2024 to find recurring patterns. They can assess whether particular roads, intersections, or road user groups account for a disproportionate share of deaths.
Such work allows agencies to direct limited resources toward interventions that address documented risks rather than relying on assumptions about the state as a whole.
