Hundreds of drivers have been caught out by the weather in recent days. While it can be dangerous there are ways to avoid the worst effects of spending hours in a cold car, miles from anywhere.
First of all, make sure you have packed your emergency snow kit. This should include warm clothing, some food, water and a mobile phone.
If you are trapped in your car, you can stay warm by running the engine. However, it is vital that the exhaust pipe is not blocked by snow. If the engine fumes cannot escape, you could be overwhelmed by carbon monoxide gas, which is highly toxic.
If there is any risk the fumes can come into the car, do not run the engine. Even if it is safe, do not run the engine for more than 10 or 15 minutes in each hour.
Stay in or close to your car. In heavy snow it is easy to get disorientated and lost or separated from your vehicle. If necessary you can always hang a piece of brightly coloured cloth on your car to let others know you are there.
