Winter is one of the most challenging times for drivers - we are hit with severe weather conditions making journeys more dangerous. The best way to keep safe is to be properly prepared and always drive with caution.

Do you need really need to drive?

If your journey is not essential, the best plan may be to stay at home and wait for the worst to pass. Ice can make roads treacherous and increase the chance of losing control of your car. We have some tips to keep you safe and prepare you for driving on ice:

Before you set off:

• Leave enough time to de-ice your windows and windscreen.
• If you are meeting someone, let them know when you expect to arrive.
• Check your tyre thread - they must be above the legal limit of 1.6mm. Tyre thread is important as the thread gives you grip on the road, reducing the chances of skidding.

Driving on icy roads:

• With roads slippery, the first thing you should do is slow down and drive gently, avoid harsh braking or aggressively steering.
• Increase your stopping distance with the car in front, as braking distances can double in icy conditions.
• If you are driving on a hill, ensure that you reduce your speed and use a lower gear to keep control, so you don’t have to use your brakes.

What is Black Ice?

Black ice is a thin, transparent layer of ice on the road surface. It usually forms when it’s been raining with very low temperatures. When black ice is present, roads can appear to merely look wet and people often don’t realise the danger before it’s too late.

If you are sliding on ice, it is advised to go against instinct and try not to brake, as your wheels will lock, and you will skid even further. Instead, the RAC advise that if you do encounter a skid, gently steer into it.
