Driving in winter, especially on
snowy, icy roads, can be less troublesome if you take a few simple precautions.
First, put on snow tires if you plan to drive on snowy, icy roads very often. Second,
check the amount of antifreeze in your radiator and add more if necessary. Next,

carry tire chains, a can of spray to unfreeze door locks, and a windshield
scraper in your car when driving in winter weather.
