It's one of the worst scenarios a driver will ever encounter. If you become trapped in deep snow or caught in a blizzard while driving, then the following precautions should help you stay safe until conditions improve or emergency help arrives.

• Once caught in deep snow, do not rev or 'gun' the engine, as this will cause the wheels to dig deeper into the snow. Instead, put the car into as high a gear as possible and slowly manoeuvre the car lightly forwards and backwards to gently creep out of the snow
• If you are stuck fast, stay in the car, unless help is visible within 100 yards
• Keep warm by running the engine and heater every ten minutes
• Beware of carbon monoxide poisoning. Keep the exhaust pipe clear of snow, and open a downwind window for ventilation
• Keep moving to maintain body circulation, but avoid over-exertion as cold weather puts added strain on the heart. Shovelling snow or pushing a car in deep snow should be avoided.

Nigel Charlesworth from Green Flag adds: "Winter conditions can be hard on vehicles and drivers alike. We advise all motorists to book their vehicle in for a pre-Winter service to reduce the chances of breakdown. Our vehicle inspectors provide a mobile service, saving you the time normally spent on taking the car to a garage.

"But if drivers do get in difficulties, we will be ready to assist round the clock, and within the quickest time possible," reassures Nigel.
