What teen drivers need to know.

• Position: YOUR LIFE

Along with the major driving holidays, bad weather contributes to a significant number of accidents on the nation's roadways, especially for younger drivers. "Snow and ice present some of the biggest challenges to any driver, but taking the right precautions and following a few simple steps can keep even young drivers safe," says John Harmata, coauthor of What Teenage Drivers Don't Know: Unwritten Rules of the Road.

Preparation is everything when driving through bad weather like winter storms and frigid cold. A thorough maintenance inspection before leaving home can save lots of grief later. Teen drivers should learn how to check tire pressure and wear, fluid levels, heater, headlamps, and brake lights. Preparation also means carefully planning one's route and leaving extra time so there is no rush.

"Don't leave home without a charged cell phone," adds Harmata, "and don't take a long journey without letting people know where you're going and when you expect to arrive."

Moreover, have the right tools on hand for a worst-case scenario, such as breaking down or being trapped by a blizzard. A well-stocked roadside emergency kit should include jumper cables, flashlights, road flares, shovel and broom, blankets, and water and snacks.

Seat belts are the single most important safety feature in a vehicle, but they only are effective when worn.
