Wintertime can pose a big threat if you are ever stranded out in the middle of nowhere. You could easily get stuck, run out of gasoline, or get caught in the middle of an unexpected winter storm and have to pull over. The storm could just as easily lift in an hour, but it could also last for days, so it is best to be prepared.
Stay Topped Off

Running into a situation where you tried to make it home in icy conditions with the fuel meter low is not something we dream about. Instead of cursing yourself when it happens, ensure you have enough gas to idle and heat your trapped car enough to keep warm.
Survival Kit

Your survival kit should include warm clothes, blankets, sleeping bags, flares, emergency candles for keeping warm, tools, chains, and necessary equipment to fix a flat, food, water, a flashlight, waterproof matches, a compass, a shovel, hand warmers, a first-aid kit, and other winter survival tools.
Snow Insulates

Remember that snow is an excellent insulator and it can help can you stay warm. Bury your vehicle to help keep drafts out and the heat in. Make sure to leave a one-inch opening in the window for fresh air and leave one door unobstructed so you can get out.
Fill It Up!

Use anything you can find to block off unused space in the vehicle that will not be used.
Short Spurts

Run your vehicle for short 15 minute intervals to warm up and then turn it back off. Make sure that the exhaust pipe is away from debris and the snow. If the exhaust pipe gets clogged up, carbon monoxide fumes can enter the cab.
Stay Bundled

Stay warm and wrap up in extra dry clothes, a sleeping bag, warm blankets, hat, gloves, and winter socks. These items are a necessity for your emergency kit.
Cuddle For Warmth

Snuggle closely together to keep warm. When you huddle together in a tiny space it both amplifies the amount of heat in the area and resolves possible frostbite in your extremities.
Keep Moving

Remember to move around to keep warm. Move your whole body including your legs, arms, feet, and toes. Moving increases circulation and warms the body.
Signals

Construct a way of signaling rescuers. A car buried in snow is easily camouflaged. Lay out colorful items around your car or in the top of a tree, set off flares, or use natural materials to form a message or symbol so it can be seen from the air.
Stay Inside

If you are stranded, stay inside your vehicle. A vehicle offers protection from the elements and it is easier for rescuers to locate you. You have a better chance of survival than if you wander off looking for help.
Signal Often

Utilize signaling devices such as a radio, mirror, or flares to request help. Use the devices often so that any passing individuals are likely to take notice.
Hydrate

Keep hydrated, but do not eat the cold snow. Place the snow in a container and hold it inside your coat so it melts faster. Do not put the container against the skin. Your body will use up needed heat to warm the snow enough to make it useful to the body.
Beware Of Carbon Monoxide

Include a carbon monoxide detector strip in your survival kit or stick it on the dashboard. This handy device detects carbon monoxide and warns you when levels are dangerous.
