When winter weather begins what is the greatest single contributing factor to collision?

The greatest single contributing factor to collisions during winter weather is often reduced traction due to icy or snowy road conditions. Drivers may underestimate the impact of slick surfaces, leading to loss of control, longer stopping distances, and increased likelihood of skidding. Additionally, inadequate vehicle preparation, such as worn tires or lack of antifreeze, can exacerbate these risks. Overall, a combination of driver behavior and environmental conditions plays a significant role in wintertime accidents.
