If you're ever trapped in a blizzard, stay in your car and wait for help.
Before the snow gets too deep, clear a space around the exhaust to let carbon monoxide escape when you run the engine and heater.
Get whatever you need from the boot into the passenger compartment; look for a tool, such as a jack handle or an umbrella, to clear an air passage if snow buries the car.
Keep warm. Put on all available clothing and cover yourself with blankets; for more insulation, stuff newspaper inside clothing. Wear a hat, or wrap your head with a scarf; you lose heat more quickly from your head than from the rest of your body. To conserve fuel, run the heater for no more than 10 minutes per hour. (Open a window slightly on the side away from drifting snow to let carbon monoxide escape.)
Stay awake. Don't drink alcohol; it causes drowsiness and cools the body, making you more susceptible to hypothermia. Be active - stretch, flex your muscles, wiggle your fingers and toes.
Limit your use of the radio and lights to conserve battery power.
If other cars are snowbound near you, join forces to sing songs or play quizzes. More people in a car will keep it warmer, boost everyone's morale and encourage you to stay awake.
