In winter, America’s roads offer an entirely new setting for you to drive in. A road you know like your own backyard during summer can morph into a hazard as snow, freezing rain and black ice start falling. Dropped visibility, frozen, slippery surfaces and constantly changing weather can prove difficult to maneuver-something that every experienced and inexperienced driver needs to look out for before traveling even just a short distance where the temperature might dip below freezing.

The statistics don’t do justice to the harshness of winter driving throughout the United States. A total of 1,579 Americans died between 2020 and 2023 in winter-weather crashes in all four corners of the country (both conditions where lakeshore ice storms coated everything, or when lake effect snow dropped feet upon feet, or when mountains bucked, but to ice covered with sleet or blowing snow.) Although winter affects every country to some degree, no two places are exposed to the exact same brand or impact.

Other states are up high in the ranks thanks to deadly combinations of severe weather and challenging road conditions either jammed interstates or rural road networks long enough that it will take time for help to arrive. Finally, some states show up on the list as a result of their relatively rare but highly problematic winter weather that blinds many drivers and their road crews. After studying nationwide federal data on crashes and driving volumes, we’ve ranked the 15 states with the highest risk of winter driving-and here’s what’s making each uniquely terrifying.

1. Michigan

What Michigan is missing is its snow and ice cover and the deadly potential these can create, especially when combined with severe Michigan winter weather, busy road systems, and relatively low vehicle speeds. From 2020 to 2023, Michigan experienced 156 winter-related road deaths, the greatest amount of anyone in the United States. A rate of 0.41 road deaths per billion vehicle miles indicates the difficulty and danger of winter driving.

Why Michigan Faces Extreme Winter Driving Risks:

• Experiencing heavy lake-effect snowstorms
• Creating dangerous whiteout driving conditions
• Increasing winter traffic collision risks
• Developing hard-to-detect black ice
• Challenging drivers across urban highways

One of the most famous sources of harsh winter roads in Michigan is our very common lake effect snow. When the cold air travels over the great lakes, heavy snow bands can easily drop several inches on our freeways in just a short amount of time. These storms can be so fierce that they can take away all visible roads within a couple minutes and create whiteouts which make it extremely difficult to navigate even well after the snowing ends.

Michigan’s challenges aren’t limited to blizzards. With its varying landscape and roads, the state also encounters problems that other areas deal with differently in the winter. The hustle and bustle of cities contribute to numerous chain-reaction accidents when slippery conditions arise, and the country’s by-ways are prone to unseen black ice. Combining the variables makes for a challenging Michigan commute in the winter.

2. Pennsylvania

Pennsylvania is the second most dangerous state for winter driving, reporting 110 winter weather fatalities over the period of the study. At 0.28 fatalities per 1 billion miles of travel on an annual basis, Pennsylvania’s driving conditions can be treacherous ranging from snowy roads high in mountain terrain to I-81 and other interstates with a large share of daily drivers experiencing varying weather on their commuting routes.

Factors Behind Pennsylvania’s Winter Driving Dangers:

• Navigating snow covered mountain roads
• Facing hazardous freezing rain conditions
• Managing heavy interstate winter traffic
• Encountering slippery icy road surfaces
• Adapting to rapid weather changes

Slippery and icy inclines add to the many challenges Pennsylvanians face when driving during winter. In mountainous areas like the Appalachian regions of Pennsylvania, elevation changes are much greater and that means they will get more ice, sleet and snow than level ground. Freezing rain, which looks like rain but is icy and not usually noticeable while you’re on the road, significantly lessens tire traction making it hard for drivers of any skill level to keep the car on the road.

Pennsylvania winter hazards depend on where you live. Urban, suburban and rural areas can have different dangers. Congestion near large metro areas adds to increased stopping distance and the chance of multiple car pileups on icy conditions and changing weather can cause traffic to stop and go fast. The state’s rural area secondary roads are also not generally treated and less lighting during a winter night can also increase the severity of safe driving on Pennsylvania’s winter.

3. Ohio

Ohio is also on a list of the third most dangerous states for winter driving as winter conditions are becoming more prevalent along our roads. Ohio was the third and fifth most deadly state in the research with 104 reported winter-weather related deaths in the time frame, averaging. 24 deaths per billion vehicles per mile. Snow can make for some rough conditions, but often conditions where it is freezing to thaw the roads can be far more deadly.

Key Winter Driving Hazards In Ohio:

• Encountering dangerous black ice conditions
• Facing freezing rain throughout winter
• Navigating busy urban traffic safely
• Managing slippery bridges and overpasses
• Adapting to changing road conditions

A particularly dangerous winter weather risk in Ohio is black ice, a treacherous, hard-to-see layer created by water that froze over a roadway. Often, bridges, overpasses and highways turn to ice long before the adjacent roads become so, leaving drivers vulnerable and ill-equipped. Sudden loss of traction particularly while braking, steering, or merging can become hazardous without much notice or caution.

Because of a mix of densely populated cities and numerous country roads, Ohio motorists in both regions experience unique driving challenges each winter: city commuters must navigate dense traffic, as any collision in these areas quickly can turn into larger-than-usual pile-ups on snow-slicked surfaces; and rural drivers face prolonged icy roads due to lack of traffic and slow clearing equipment.

4. Alaska

Alaska only comes in fourth among the 10 most dangerous states for winter driving; the key difference is that its fatality rate from such incidents, 1.35 out of every 1 billion miles driven on winter roads, leads the country. When considering its relatively small number of residents, you will always be driving in unknown and challenging terrain when it comes to Alaska. Weather can quickly turn on a dime into something to watch for-and avoid if you want to make it safely.

Extreme Winter Conditions Across Alaska:

• Driving through long dark winters
• Facing severe snow and ice
• Navigating remote isolated highways safely
• Managing sudden weather condition changes
• Preparing for emergency travel challenges

The harsh Alaskan winters with short days mean extremely reduced visibility for drivers. Black ice is a common problem on roads, and a severe winter storm can result in conditions that are the visual equivalent of driving through solid white, with less than a few feet of vision in front. Additionally, the significant travel distances between communities can leave drivers unable to reach help as weather deteriorates.

The distance within the state also increases Alaska’s risk in terms of winter traveling: Numerous roads travel through wilderness areas where response time to accidents could be long (several hours to respond time). “Cars can break down or drive into snowy or icy terrain when the temperature is far below zero which can pose very real threats,” explains John H. (from Gadsden, AL) who had “had my own vehicle stuck multiple times in Alaska during severe winters.”

5. Illinois

The most dangerous states to drive for the 2016 winter season it may not possess the steep mountains of West Virginia, how ever Illinois is 5th highest dangerous state for to the summertime driving condition, because of 95 people summertime driving-related demise, and a passing rating pertaining to 0.24 fatalities per mile each per trillion vehicle. Due to chilly precipitation, icy streets, and the populace of Chicago, roadway problems vary from normal to dangerously hazardous during the summertime months, creating brief journeys more risky.

Major Winter Driving Risks In Illinois:

• Encountering freezing rain on highways
• Facing heavy urban traffic congestion
• Driving across dangerous black ice
• Managing strong winds and snowdrifts
• Adapting to rapid road changes

Freezing rain it can be treacherous traveling through the busy, dense, chained to the ice conditions on Midwestern highways, which lead to often devastating pile ups. Even 15 to 20 minutes of freezing rain can transform the busiest of freeways into icy nightmares where distances to brake become treacherous and the probability of crashing is amplified by each passing vehicle; freezing precipitation tends to occur overnight creating “black ice” roads before drivers realize driving should slow considerably.

In addition to winter weather within its metropolitan areas, Illinois experiences winter-related driving dangers in rural areas as well. The powerful wind funneled over open farmland areas can cause snow to blow over, blocking traffic lanes with drift or obscure views, while country back roads in shady areas that face winter sun exposure can remain slick, long after a winter storm system moves out of the region. Combined these make it one of the toughest states in the USA to drive this time of year safely.

6. Wyoming

Being named as one of the 6 most dangerous states to drive in the winter, especially considering a deadly accident rate of 1.01 deaths per every one million vehicles, Wyoming is deadly due to its open plains and extreme winter weather conditions. Not that we’re going for, even considering Wyomings 40 total deaths due to winter conditions, the second of all states. Many high traffic plains roads will get you stuck out with no hope with poor winter visibility.

Extreme Winter Challenges Across Wyoming:

• Facing powerful winds and whiteouts
• Driving on dangerous black ice
• Navigating long remote highway routes
• Preparing for severe winter conditions
• Managing travel through isolated areas

Perhaps none of Wyoming’s winter dangers is more common or insidious than wind which, on an especially wild day, can blast snow sideways onto the roadways, causing flash white-outs reducing visibility to near nothing. Plow-able drifted snow can bury portions of roadways entirely and black ice can form on the bare highway slick without even the challenge of the curves. This usually necessitates roadway closings especially on the interstates.

Wyoming’s location also contributes to some of the inherent dangers of traveling throughout the winter. Most communities within the state are so isolated from each other that if motorists break down or find themselves without gas, safe shelter or emergency services, there’s nowhere nearby they can go. A motor vehicle malfunction and subsequent stranding in extremely frigid conditions can easily turn deadly in an instant. Proper planning, winterizing gear, and frequent weather checking should definitely be part of any traveler’s Wyoming itinerary in the cold weather.

7. Montana

With rugged terrain, a tendency for intense snowstorms and an unusually high winter driving death rate of 0.87 fatalities per 1 billion miles driven, Montana is tied at No. 7 as the nation’s riskiest winter road state. There were 46 winter weather-related traffic fatalities in the state over the time period for the report. Combining treacherous mountainous terrain, extensive rural roads, and uncooperative winter weather patterns, the conditions are ripe for alert driving through the snow season.

Challenging Winter Roads Across Montana:

• Facing severe mountain snowstorms
• Driving through rugged rural highways
• Managing dangerous snow and ice
• Preparing for remote winter travel
• Navigating steep mountain passes safely

Montana’s mountains and open plains are susceptible to fast-developing blizzards that cut visibility to zero long before motorists have a chance to get off the road. Intense wind and drifting snow can combine to cover roads with the snow, and hide a slick and icy surface underneath a blanket of snow. Mountain road grades and curves are especially treacherous due to the packed snow and ice.

Montana’s broad open spaces do, of course, add to the risks of winter driving. A number of Montana’s routes traverse some incredibly isolated stretches with few other cars. Help may be a considerably longer walk away (whether it will do you any good or not depends on the temperature in more ways than one) than if you encounter some trouble back towards town. Something going wrong in the extreme cold-especially if you’re going off the side of the road in the middle of the wilderness-can quickly become a crisis.

8. Colorado

Colorado falls eighth in this year’s report of winter hazard ranking states. Its majestic mountains and volatile weather contribute to challenging road driving conditions. During 2008, Colorado faced 63 winter weather fatalities, or 0.30 deaths per billion miles. While the state’s scenic routes are inviting all year round, during the winter they often become among the most perilous drives.

Winter Driving Challenges Across Colorado:

• Navigating steep mountain passes safely
• Facing rapid weather condition changes
• Driving on snow and ice
• Managing strong winds and visibility
• Preparing for high elevation travel

The Rocky Mountains present an especially varied mix of hazards during the winter months. Motorists are challenged by steep grades, winding routes and elevated speeds and elevations that diminish traction and visibility when roads are covered by snow or ice. Since these events can unfold without advance notice, drivers can face newly fallen snow on the roadway and a hazardous flash of black ice in shady areas in mere minutes especially for those unaccustomed to mountain-driving nuances.

After you start dropping from the highest altitudes, the winds increase and a tremendous amount of blowing snow will make it nearly impossible to see down an open highway. Mountain pass roads need even more attention as morning ice develops following daytime melting. Good trip preparation, vehicle checks, and awareness of the constantly changing conditions of a winter visit will lead to a much safer experience in Colorado.

9. Wisconsin

Worst state to drive in during winter in Wisconsin, residents endure long and brutal winters, filled with days of snowy roads and freezing temps that are sure to turn roads slick and dangerous. For the data timeframe, we looked at Wisconsin’s winters, the state has been the scene of 74 winter deaths over our study frame, and this equated to a fatality rate of 0.29 for every billion miles driven. With such consistent snowfall the harsh and long cold can make navigating a danger for even the best of us the long months ahead.

Common Winter Driving Risks In Wisconsin:

• Driving through heavy snowstorms safely
• Encountering dangerous black ice conditions
• Managing freezing temperatures on roads
• Navigating rural highways during winter
• Adapting to changing weather conditions

Heavy snow can also drastically limit drivers’ vision, and a consistent cold spell means that packed snow and ice will stick to the road longer than usual. Black ice is most dangerous in the early mornings and at the beginning of the evenings because temperatures remain below freezing for hours at a time. Roadways that are otherwise dry can turn slick, leading to a loss of traction if a speed adjustment isn’t made.

Travel also is more difficult due to Wisconsin’s rural roads which travel through communities where help can take some time to arrive if it is needed during storms. Drifts, strong wind often drive snow drifts in large drifts that completely block the road ways making you unable to pass. It is important to be driving slowly, be aware of what your car is doing, and avoid being too close to other vehicles that you will run into during winter conditions on the roads of Wisconsin.

10. Minnesota

Minnesota ranks tenth among the most dangerous states for winter driving, reflecting its reputation for experiencing some of the coldest winters in the United States. Between 2020 and 2023, the state recorded 70 winter-weather fatalities and a fatality rate of 0.31 deaths per billion vehicle miles traveled. Extended periods of subfreezing temperatures keep snow and ice on highways, city streets, and rural roads, creating persistent winter driving hazards.

Major Winter Driving Hazards In Minnesota:

• Facing powerful blowing snowstorms
• Encountering hidden black ice conditions
• Navigating snow covered rural highways
• Managing extreme freezing temperatures
• Adapting to sudden visibility changes

Blowing snow is one of Minnesota’s most serious winter hazards, as strong winds frequently reduce visibility and create deep snowdrifts across roadways. Drivers traveling through open farmland can suddenly encounter whiteout conditions that make lane markings difficult to see and require immediate reductions in speed. These rapidly changing conditions demand constant attention and careful decision-making behind the wheel.

Extreme cold further increases the risks by allowing moisture to freeze quickly on road surfaces, forming black ice that is difficult to detect before vehicles lose traction. Rural highways often remain icy long after storms have passed, while heavy urban traffic adds another layer of danger during busy commuting periods. Safe winter driving in Minnesota depends on patience, appropriate speed, proper vehicle preparation, and close monitoring of weather forecasts.

11. Indiana

Indiana ranks eleventh among the most dangerous states for winter driving, proving that serious winter road hazards are not limited to mountainous regions or areas with exceptionally heavy snowfall. During the study period, the state recorded 69 winter-weather fatalities and a fatality rate of 0.21 deaths per billion vehicle miles traveled. Its central location and extensive highway network expose drivers to freezing rain, icy roads, and heavy traffic throughout the winter season.

Key Winter Driving Risks In Indiana:

• Facing hazardous freezing rain events
• Driving on slippery icy highways
• Managing heavy interstate traffic flow
• Navigating untreated rural roadways
• Adapting to sudden weather changes

Indiana’s busy interstate system carries a continuous mix of passenger vehicles and commercial trucks, increasing the risk of multi-vehicle collisions when winter weather develops. Freezing rain frequently creates a thin layer of ice that is difficult for drivers to detect, significantly reducing tire traction. Rapid weather changes can quickly turn normal driving conditions into hazardous situations, requiring motorists to remain alert at all times.

Although Indiana generally receives less snowfall than some neighboring northern states, winter storms still create widespread travel challenges. Rural roads may remain untreated for longer periods, while congested urban highways experience longer stopping distances and greater crash risks on icy pavement. Together, these conditions make Indiana a state where careful driving, reduced speeds, and close attention to weather forecasts are essential throughout the winter months.

12. New York

New York ranks twelfth among the most dangerous states for winter driving after making one of the largest jumps in the rankings. During the study period, the state recorded 63 winter-weather fatalities and a fatality rate of 0.14 deaths per billion vehicle miles traveled. Its diverse geography creates very different winter driving conditions, ranging from congested city streets to snow-covered highways across upstate regions.

Winter Driving Challenges Across New York:

• Experiencing intense lake-effect snowfall
• Facing rapidly changing road conditions
• Managing heavy urban traffic safely
• Navigating snow covered rural highways
• Preparing for severe winter weather

Lake-effect snow is one of New York’s most significant winter hazards, particularly in areas near the Great Lakes. Western parts of the state can experience intense snow bands that quickly reduce visibility and make highways extremely difficult to navigate. Drivers traveling through these regions may encounter dramatically different weather conditions within only a few miles, making careful planning and preparation essential.

Urban and rural areas each present their own winter driving challenges across the state. Busy city roads become more hazardous with freezing rain, icy intersections, and heavy traffic during peak travel hours, increasing the likelihood of collisions. Meanwhile, rural highways and mountainous regions often remain snow-covered long after major storms have passed. Together, these conditions make New York one of the country’s more demanding states for winter travel.

13. Texas

Texas ranks thirteenth among the most dangerous states for winter driving, despite not being widely known for severe winter weather. Between 2020 and 2023, the state recorded 51 winter-weather fatalities, with a fatality rate of 0.04 deaths per billion vehicle miles traveled. Although snowfall is uncommon across much of the state, freezing rain and ice storms can rapidly transform highways into dangerous travel routes.

Unexpected Winter Driving Hazards In Texas:

• Facing dangerous freezing rain events
• Driving on icy bridges safely
• Managing limited winter driving experience
• Navigating widespread ice storm impacts
• Adapting to sudden weather changes

One of the greatest winter driving challenges in Texas is the lack of frequent icy conditions, leaving many motorists with limited experience driving on frozen roads. Freezing rain can quickly coat bridges, overpasses, and highways with a thin layer of ice, causing vehicles to lose traction with little warning. In heavily populated metropolitan areas, these slippery conditions often lead to traffic congestion and multi-vehicle collisions.

Texas’ enormous geographic size also increases the impact of winter weather whenever major storms develop. Long interstate highways connect large cities through remote areas where changing weather conditions can surprise drivers during their journeys. While severe winter events occur less often than in northern states, freezing temperatures and ice storms can still create widespread travel disruptions, making careful driving and weather awareness essential.

14. South Dakota

South Dakota ranks fourteenth among the most dangerous states for winter driving, proving that a smaller population does not necessarily result in lower winter road risks. During the study period, the state recorded 20 winter-weather fatalities, producing a fatality rate of 0.50 deaths per billion vehicle miles traveled. This rate is higher than that of many states ranked above it, highlighting the serious dangers winter conditions create across the Great Plains.

Severe Winter Travel Risks In South Dakota:

• Facing powerful winds and snowdrifts
• Driving on dangerous black ice
• Navigating remote rural highways
• Preparing for extreme winter weather
• Managing long distance winter travel

South Dakota’s wide-open landscapes leave highways exposed to strong winds that frequently blow snow across roadways, creating deep drifts and reducing visibility. Black ice develops quickly on exposed pavement during periods of intense cold, making even familiar routes unexpectedly hazardous. These conditions can turn long-distance travel into a demanding experience, even for drivers accustomed to winter weather.

The state’s rural environment further increases winter driving risks, as many highways pass through isolated areas where emergency assistance may take longer to arrive. A vehicle becoming stranded in freezing temperatures can quickly become a dangerous situation without proper preparation. Careful trip planning, monitoring weather forecasts, reducing speed during storms, and carrying essential winter supplies are all important steps for safe travel across South Dakota during the colder months.

15. Oregon

Oregon ranks fifteenth among the most dangerous states for winter driving because of the wide variety of weather conditions experienced across the state. During the study period, Oregon recorded 34 winter-weather fatalities, resulting in a fatality rate of 0.24 deaths per billion vehicle miles traveled. From the snow-covered Cascade Mountains to coastal highways where rain can quickly freeze, drivers must be prepared for rapidly changing winter conditions throughout their journeys.

Diverse Winter Driving Challenges In Oregon:

• Navigating snow covered mountain passes
• Facing dangerous black ice conditions
• Managing freezing fog and rain
• Adapting to rapid weather changes
• Driving safely across varied terrain

Mountain passes are among Oregon’s most demanding routes during the winter months. Heavy snowfall, steep inclines, and icy curves make travel especially challenging when storms move through higher elevations. Drivers often experience dramatic weather changes while traveling between valleys and mountainous areas, requiring constant attention and careful adjustments to their driving.

Coastal and inland regions present their own unique winter hazards, including freezing fog, black ice, and rain that turns into ice as overnight temperatures drop. These changing weather patterns mean motorists may encounter several different road conditions during a single trip. Staying alert, allowing extra travel time, and reducing speed to match road conditions are essential steps for safer winter driving throughout Oregon.
