Snow and ice have a habit of catching us out when we least expect it. Snow can fall thick and fast from nowhere, whereas ice on roads can be invisible to the naked eye. If you do have to drive, Green Flag advises the following:

• Make sure all passengers are wearing seat belts
• Use the defroster and windshield wipers for better visibility
• Check your speed and turn slowly, even if the roads have been gritted
• Give more warning than usual to other drivers when turning, stopping or changing lane
• Keep plenty of distance between cars. You never know when you'll hit an icy spot. If you pass the same landmarks as the car in front of you within three seconds, you are following too closely
• Pump the brakes slowly and gently if your car does not have antilock brakes. Constant pressure can cause them to lock and skid
• Be extra wary of black ice - it is an invisible danger that can catch out the most careful driver
• Approach corners at a steady speed, in as low a gear as possible. Don't touch the clutch unless it is absolutely necessary, steer smoothly and avoid braking on the bends
