This is what the Institute of Advanced Motorists recommends for driving in snow and ice.
When driving in snow, get your speed right – not too fast so that you risk losing control, but not so slow that you risk losing momentum when you need it – and brake, steer and accelerate as smoothly as possible.
Start gently from stationary, avoiding high revs. If you get yourself into a skid the main thing to remember is to take your foot off the pedals and steer.
Only use the brake if you cannot steer out of trouble.
Double or even triple your normal stopping distance from the vehicle in front. Drive so that you do not rely on your brakes to be able to stop – on an icy surface they simply may not do that for you!
If your vehicle has ABS in very slippery conditions it will not give you the same control it would in others. Do not rely on it.
Plan your journey around busier roads as they are more likely to have been gritted. Avoid using shortcuts on minor roads – they are less likely to be cleared or treated with salt, especially country lanes.
On motorways stay in the clearest lane where possible, away from slush and ice. Keep within the clear tyre tracks if you can.
Stay in a higher gear for better control, and if it is slippery, in a manual car move off in a higher gear, rather than just using first.
On a downhill slope get your speed low before you start the descent, and do not let it build up – it is much easier to keep it low than to try to slow down once things get slippery
In falling snow use dipped headlights or foglights to make yourself visible to others (especially pedestrians) – but as conditions improve make sure your foglights are only on if necessary as they can dazzle other drivers
If you are following another vehicle at night, using their lights to see ahead can cause you to drive dangerously close – keep well back from other traffic.
