Motorists should clear snow off their entire car, including the roof and headlights. Snow piled up on the roof and bonnet could fall, reducing visibility for the driver of the vehicle or fall into the path of another vehicle or a pedestrian.
Watch out for icy conditions - look for clues such as ice on the pavement or on your windscreen before you start your journey and take extra care.
- Try not to brake suddenly - it may lock up your wheels and you could skid further.
- Look out for winter service vehicles spreading salt or using snow ploughs. They have flashing amber beacons and travel at slower speeds - around 40mph.
- Stay well back because salt or spray can be thrown across the road.
- Do not overtake unless it is safe to do so - there may be uncleared snow on the road ahead.
