قاعدهٔ ۲۳۵ — هنگام رانندگی در مه

When driving in fog you should

• use your lights as required (see Rule 226)
• keep a safe distance behind the vehicle in front. Rear lights can give a false sense of security
• be able to pull up well within the distance you can see clearly. This is particularly important on motorways and dual carriageways, as vehicles are travelling faster
• use your windscreen wipers and demisters
• beware of other drivers not using headlights
• not accelerate to get away from a vehicle which is too close behind you
• check your mirrors before you slow down. Then use your brakes so that your brake lights warn drivers behind you that you are slowing down
• stop in the correct position at a junction with limited visibility and listen for traffic. When you are sure it is safe to emerge, do so positively and do not hesitate in a position that puts you directly in the path of approaching vehicles.
