Staying Safe in the Most Dangerous States for Winter Driving

The number of fatalities caused by winter auto accidents increased slightly from 374 to 395 from 2020 to 2021. Winter driving continues to be hazardous — especially if you live in one of the states below.

To underscore the importance of safe driving this winter, MoneyGeek analyzed data from the National Highway Traffic Safety Administration’s (NHTSA) Fatality Analysis Reporting System and ranked the most dangerous states for winter driving. We also explored steps drivers can take to prepare for winter weather and stay safe on the road.

• On average, 403 drivers die per year on snowy or icy roads.

• Michigan is the most dangerous state for winter driving, with an average of 39 deaths on the roads every winter. The next most hazardous states for winter driving are Alaska, Ohio and Pennsylvania.

• Alaska had the highest winter driving fatality rate per billion lane mile of any state (1.65), followed by Wyoming (1.00), Vermont (0.75) and Montana (0.73).

While most of us can't avoid driving in icy and snowy conditions every winter, some states are more dangerous than others.

MoneyGeek analyzed data from the NHTSA's Fatality Analysis Reporting System for 2019 to 2021 — the most recent data available — to rank the worst states for winter driving. Our ranking of the most dangerous states for winter driving incorporated total fatalities in winter driving conditions, the fatality rate adjusted for vehicle miles traveled in the state and the state's score on our ranking of the states with the safest drivers.

We found that when road conditions included sleet, snow, blowing snow or freezing drizzle, Michigan ranked as the worst state for winter driving overall, while Alaska had the highest winter driving fatality rate.

Our top 15 list doesn't include some surprising states that experience significant winter weather, like Massachusetts and New Jersey.

Like a good Scout, it's a good idea to adopt the motto "be prepared" when it comes to winter driving. Keeping emergency supplies in your trunk is a key part of practicing travel safety. Tuck these items in the back now so they are there when you need them:

• Spare tire
• Chains
• Snow shovel
• Ice scraper
• Jumper cables
• Sand or kitty litter
• Flashlight
• Blanket
• Water
• Food/snacks
• Cell phone charger
• Medications

Before you leave for a ski vacation or a trip to Grandma’s house, you should plan your travel, checking the weather and road conditions as well as your route. Always give yourself extra time to drive slower.

If you're traveling with kids, make sure they’re safely buckled in a car seat. While you may want to keep them bundled up in their winter coat, this can interfere with the fit. Always remove your child’s thick outerwear, buckle them up and then place blankets or coats over the secure harness.

To determine which states are most dangerous for winter driving, MoneyGeek analyzed data from the National Highway Traffic Safety Administration’s (NHTSA) Fatality Analysis Reporting System (FARS) for 2019–2021.

Using FARS data, we calculated each state’s winter driving fatality rate adjusted for vehicle miles traveled, as well as the total winter fatalities in each state. We also utilized the results of a MoneyGeek analysis of the states with the best and worst drivers.

To calculate each state's Winter Driving Score, we weighted the factors mentioned above. Total Winter Driving Fatalities was given double weight, Winter Driving Fatality Rate was given full weight and Safe Driver Score was given half weight.

The data points presented are defined as follows:

• 2023 Rank: The state’s winter driving rank for MoneyGeek’s 2023 study based on its "Final Winter Danger Score," with a lower rank indicating more dangerous winter driving conditions.
• 2022 Rank: The state’s winter driving rank for MoneyGeek’s 2022 study based on its "Final Winter Danger Score," with a lower rank indicating more dangerous winter driving conditions.
• Final Winter Danger Score: Total Winter Driving Fatalities, Winter Driving Fatality Rate and Safe Driver Score were each converted to a 100-point scale and weighted. We based the final ranking of states on that score.
• Total Winter Driving Fatalities (2019–2021): Driving fatalities reported by the NHTSA where road conditions included sleet, snow, blowing snow or freezing drizzle for the most recent three years of data 2019–2021. This metric is given double weight in the calculation of the final winter danger score.
• Winter Driving Fatality Rate: The rate of winter driving fatalities per billion vehicular miles traveled. This metric is given full weight in the ranking.
• Safe Driver Score: The final score calculated by MoneyGeek in its rating of the states with the safest and worst drivers. For this analysis, the scores have been scaled to range from 0 to 100, with 100 being the safest. This metric is given half weight.
