Winter weather creates more than slick roads. In the US, weather-related crashes account for about 21% of all crashes each year, and winter snow and ice drive over 900,000 incidents annually. The pattern changes fast when speed, visibility, and road friction collide, so the most common hazards show up in different places across the season.
Key Takeaways
- 65% of drivers exceed safe speeds on snow per observational studies.
- In the US, approximately 116 vehicle crashes occur every hour during snowy conditions according to NSC estimates.
- In the United States, weather-related vehicle crashes account for approximately 21% of all crashes annually, with winter weather like snow and ice being primary contributors causing over 900,000 crashes per year.
- Snow reduces visibility to less than 1/4 mile in 70% of severe winter storms per NOAA.
- Winter tires reduce crashes by 30% when used properly per EU studies.
Winter weather driving leads to more accidents, so slowing down and planning ahead can save lives.
