Auto accidents are the leading cause of death during winter storms. So, if you should ever find yourself driving on snow or ice-covered roads, remember these tips.

Listen to the forecast before you leave. If you know a bad storm is on the way, you may be able to delay your trip or chose an alternate route that might not be hit as hard.
Watch for ice. Take extra care when driving on bridges and overpasses; they're typically the first parts of the road to freeze over. Also, remember that black ice can be anywhere. Black ice is that icy coating that allows the color of the road to show through, making the ice very difficult to see.
Slow down. The consequences of driving too fast on slippery roads are never worth any time you might save by speeding. 
Stay alert. Make sure you're aware of other drivers around you.
Stay in control. If the back end of your vehicle begins to skid (also known as "fish-tailing"), turn in the direction of the skid and keep your foot off the brake and gas pedals. If you must brake on a slippery surface, pump the brakes gently unless you have ABS (Anti-lock Braking System). If you have ABS, press the brake firmly and hold it down. Do not pump the brakes if you have ABS. This will lessen their effect.
Avoid steep hills if possible. Use alternate routes to avoid hills. Even if they do take you out of your way, you may be able to stay safer. 
Keep enough distance between you and other cars. Slick conditions can triple the distance it takes to come to a complete stop. So, allow more room than you think you need to stop safely.
Always buckle up! This tip applies year 'round, no matter what the driving conditions.
