What you put in your kit is up to you. Some ideas are.........
Warm hat gloves socks and jacket.
Candles and candle holder.
|I put this kit together in 5min.|
You should plan to be able to spend at least 48hrs stuck in your car in sub zero temperatures without a working engine. You can not count on your engine in a survival situation as it may not work for a number of reasons. If you do have a working engine that's a fantastic bonus but be careful. Many people have died from carbon monoxide poisoning while sleeping in a car. Never sleep with the car running. Just turn it on to warm up then shut it off.
Make sure the exhaust pipe is clear. Snow or other debris can build up around your vehicle trapping the exhaust fumes. Don't let drifting snow trap you. While snow is a great insulator and actually will make your vehicle warmer you don't want to be trapped. So open a door every hr or so and clear the snow away.
And be careful with your candles. Don't sleep with your candle burning. Cars have lots of flammable fabric and plastic and can go up like a torch if you knock over your candle.
The few ideas I have discussed here are just a start. I recommend you have a much better kit than the one on this page. But anything is better than nothing.
