During your journey remember the following:
- keep a sharp lookout for pedestrians, cyclists and other vulnerable road users
- keep your windows clear of snow during your journey
- manoeuvre gently and avoid harsh braking, acceleration or steering as these can induce a skid
- use the highest gear possible to reduce the engine revs as this will help avoid wheel spin.
