Vehicle Handling
Your fog lights must only be used when visibility is reduced to 100 metres (328 feet) or less. You need to be familiar with the layout of your dashboard so you're aware if your fog lights have been switched on in error, or you've forgotten to switch them off.
Vehicle Handling
The engine will need more power to pull the vehicle up the hill. When approaching a steep hill you should select a lower gear to help maintain your speed. You should do this without hesitation, so that you do not lose too much speed before engaging the lower gear.
Vehicle Handling
Having tyres correctly inflated and in good condition will make sure they have maximum grip on the road; how well your tyres grip the road has a significant effect on your car's stopping distance.
Vehicle Handling
Try to look and plan well ahead. Plan your approach to hazards and select the correct gear in good time. This will help give you the control you need to deal with anything unexpected that may occur.
Vehicle Handling
If you’re driving on a motorway at night or in poor visibility, you must always use your headlights, even if the road is well lit. Other road users must be able to see you, but you should avoid causing dazzle.
Vehicle Handling
Rear fog lights shine more brightly than normal rear lights, so that they show up in reduced visibility. When the visibility improves, you must switch them off; this stops them dazzling the driver behind.
Vehicle Handling
Consider whether the increased risk is worth it. If the weather conditions are bad and your journey is not essential, then do not drive. If you have to drive, make sure you're well prepared in case you get stuck.
Vehicle Handling
Only use your fog lights when visibility is seriously reduced. Use dipped headlights in poor conditions because this helps other road users to see you without the risk of causing dazzle.
Vehicle Handling
You will not be able to see as far ahead in fog as you can on a clear day. You'll need to reduce your speed so that, if a hazard looms out of the fog, you have the time and space to take avoiding action. Travelling in fog is hazardous. If you can, try to delay your journey until it has cleared.
Vehicle Handling
If you have to drive in fog, switch your dipped headlights on and keep all your windows clear. You should always be able to pull up within the distance you can see ahead.
