On ice, crawl. While driving over bridges and through shady spots, be especially alert for ice. These areas freeze earlier and stay frozen longer than the rest of the roadbed. You don't want to make any sudden moves on slippery roads. Make yourself visible .

School bus drivers do it. Some new cars give you no choice but to do it. It's time for you to do it, too. Day or night, but especially in bad weather, turning on your headlights will make your car easier to see. Make THEM visible too .
