Braking can be more difficult when driving in snow and driving on ice, so go more slowly and multiply your usual stopping distance between your car and the car in front by as much as 10 times, particularly on very icy roads.
Avoid skidding by braking gently, and take extra precautions to only drive when you are well-rested and alert. Stay in your lane and give other vehicles plenty of room, and turn off cruise control as this can increase your risk of skidding. Unless the roads have been gritted, you should also avoid driving directly in the tracks made by other vehicles if driving in snow or on ice, as packed snow can be harder to grip than fresh snow.
If you’re travelling somewhere remote, it’s worth keeping some emergency supplies in your car too in case you get stranded by the weather, such as food, warm clothing and a torch.
