Install good winter
tires.
Make sure the tires have adequate tread. All-weather radials are usually adequate for most
winter conditions. However, some jurisdictions require that to drive on their roads,
vehicles must be equipped with chains or snow tires with studs.
Keep a windshield
scraper and small broom for ice and snow removal.
Maintain at least a
half tank of gas during the winter season.
Plan long trips
carefully.
Listen to the radio or
call the state highway patrol for the latest road conditions.
Always travel during
daylight and, if possible, take at least one other person.
Dress warmly.
Wear layers of loose-fitting, layered, lightweight clothing.
Carry food and water.
Store a supply of high energy "munchies" and several bottles of water.

Frostbite and
Hypothermia 
Frostbite is a severe reaction to cold
exposure that can permanently damage its victims. A loss of feeling and a white or pale
appearance in fingers, toes, or nose and ear lobes are symptoms of frostbite.
Hypothermia is a condition brought on when the body
temperature drops to less than 90 degrees Fahrenheit. Symptoms of hypothermia include
uncontrollable shivering, slow speech, memory lapses, frequent stumbling, drowsiness, and
exhaustion.
