Bad weather, such as torrential rains, storms, fog, ice and snow, can catch many motorists off-guard.
The Road Safety Authority says that while it is best to avoid making a trip unless absolutely necessary, motorists should be prepared and drive with care and caution.
The advice is to expect the unexpected.
l Remove all snow from your vehicle, as it can drop on to the windscreen when braking. Clear the windows and mirrors before you set out. Carry a screen scraper and de-icer, but never use hot water on the windscreen as it can crack the glass.
l Allow extra room between your vehicle and the one in front. It takes longer to stop in icy conditions. Use the highest gear possible to avoid wheel spin.
l Avoid harsh braking and acceleration. Watch for black ice, especially in sheltered areas. Check your tyres to ensure they are correctly inflated.
