What to Do if You Get Stranded

Staying in your vehicle when stranded is often the safest choice if winter storms create poor visibility or if roadways are ice-covered. These steps will increase your safety when stranded:

Stay in the car. Do not leave to search for assistance unless help is visible within 100 yards. It’s very easy to become disoriented or lost in blowing and drifting snow.

Display a trouble sign. Tie a brightly colored cloth on the radio antenna and, if the engine is already cold, raise the hood.

Move anything you need from the trunk into the passenger area.

Wrap your entire body, including your head, in whatever is handy to help maintain body heat. Use extra clothing, blankets, maps, newspapers, or even removable car mats for added insulation.

Stay awake. You will be less vulnerable to cold-related health problems.

Keep the exhaust pipe clear of snow – this will reduce the risk of carbon monoxide poisoning. Run the motor (and heater) for about 10 minutes per hour, opening one downwind window slightly to let in air. Also, turn on the car's dome light while the car is running.

Do minor exercises. As you sit, clap your hands and move your arms and legs occasionally to improve your circulation and stay warmer. Try not to stay in one position for too long. Avoid overexertion.

If more than one person is in the car, huddle together for warmth. If you must sleep, take turns.

Do not eat unmelted snow because it will lower your body temperature

I know there's another site.. but i can't think of it. I think it is what do you do in this situation.

If you're awake you're moving and you stay warm by moving around. If you stop moving you will get colder.
