If You're Trapped in a Car

      If you do find yourself trapped in your vehicle:

      • Stay in the car.
      • Do not leave the car to search for assistance unless help is visible within one-hundred yards. You may become disoriented and lost is blowing and drifting snow.
      • Display a trouble sign. Hang a brightly colored cloth on the radio antenna and raise the hood.
      • Occasionally run engine to keep warm.
      • Turn on the car's engine for about ten minutes each hour.
      • Beware of carbon monoxide poisoning.
      • Keep the exhaust pipe clear of snow, and open a downwind window slightly for ventilation.
      • Do minor exercises to keep up circulation.
      • If more than one person is in the car, take turns sleeping and, for warmth, huddle together.
