Driving too fast is the biggest snow driving error [source: Dunlop]. Drivers have a bad habit of thinking that once they've reached the highway they're fine to drive at their usual high speed. Wrong.
When your car starts to slip and you're heading for a crash, every second counts. Driving too fast reduces the amount of time you have to react and increases the severity of any collision. It also takes four to 10 times longer to brake on icy or snowy pavement than it does on dry asphalt [source: De Paula].
You should slow your speed when the temperature is close to freezing and sleet and snow have begun to fall. Remember that there's no right speed zone to be traveling in when it's snowing, so you need to pay close attention to the road conditions and how your car is handling to gauge a safe speed.
