Many drivers find themselves caught off guard during the winter's first snow. In fact, the most dangerous day to be on the roads is the day after the first snowstorm [source: Elliott]. Drivers haven't prepared their cars for the wintry weather, and they've probably forgotten their snow driving techniques from last year.
To ready your car for the winter, check that each of your tires has at least a 6/32-inch (4.8-millimeter) deep tread. All-weather tires can handle most driving conditions, but if you live in an area that gets a lot of snow, you should consider purchasing snow tires. Check your antifreeze levels and battery power and make sure that your defroster and rear window defogger work.
As far as the inside of your car goes, purchase a snow shovel and kitty litter or sand for digging yourself out of a jam and giving your vehicle traction. Flares, a flashlight and a snow scraper should also be kept in your car. Finally, consider signing up for a winter driving class in your area.
