Have emergency a "Winter Storm Survival Kit" in the car:
Container of sand
Tow chain or rope
High energy foods
Blankets or sleeping bags
Heavy gloves or mittens, extra woolen socks and winter headgear
Small can and water-proof matches to melt snow for drinking water (Do not eat snow, it will lower your body temperature. Melt it first.).
Travel by daylight and use major highways if you can. Keep the car radio turned on for weather information and advice. Road Report 1-866-696-3511.
If you car breaks down during a storm, or if you become stalled or lost, don’t panic. Don’t leave the vehicle. Your car provides more safety than attempting to walk during storms and periods of extreme cold. If you are on a well-traveled road, show a trouble signal. Set your directional lights to flashing, raise the hood of your car, or hang a cloth from the radio aerial or a car window. Then stay in your car and wait for help to arrive. Run the engine about ten minutes each hour to stay warm, and open the windows for a little fresh air to avoid carbon monoxide poisoning. Make sure the exhaust pipe is not blocked.
