Winter Is A Killer On average, weather-related car crashed kill 6,253 people and injure more than 480,000 each year. Most accidents occur when the roadways are wet, snowy, or icy. When weather takes a turn for the worse, take precautions to protect yourself and others. Whether there is a coating of snow or ice, or the road just looks wet, SLOW DOWN! If the temperature is near freezing outside, drive like you're on ice- you may be! For more information and tips to get your vehicle winter-ready, go to the NOAA Website.
