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.

The draught caused by other vehicles – particularly those with high sides – could be strong enough to push you out of your lane. Be prepared for a sudden gust of wind as you overtake large vehicles. Keep both hands on the steering wheel to help you keep full control.

If you’re following another road user in fog, stay well back. The driver in front will not be able to see hazards until they’re close and might need to brake suddenly. Also, the road surface is likely to be wet and could be slippery.

If you have to park your vehicle in foggy conditions, try to find a place to park off the road. If this is not possible, park on the road facing in the same direction as the traffic. Leave your parking lights switched on and make sure they're clean.

If the headlights of an oncoming vehicle dazzle you, slow down or, if necessary, stop. Do not close your eyes or swerve, as you'll increase your chances of having a collision. Do not flash your headlights either, as this could dazzle other drivers and make the situation worse.

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.

Switch off your fog lights if the weather improves, but be prepared to use them again if visibility reduces to less than 100 metres (328 feet).

Do not forget to switch off your fog lights when the weather improves. You could be prosecuted for driving with them on in good visibility. The high intensity of rear fog lights can dazzle drivers behind and make your brake lights difficult to notice.

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.

Chains can be fitted to your wheels in snowy conditions. They can help you to move off without wheelspin, or to keep moving in deep snow. You'll still need to adjust your driving to suit these conditions.

You should brake and slow down before selecting a lower gear. The gear can then be used to keep the speed low and help you control the vehicle. This is particularly helpful on long downhill stretches, where brake fade can occur if the brakes overheat.

Letting your vehicle roll or coast in neutral reduces your control over steering and braking. This can be dangerous on downhill slopes, where your vehicle could pick up speed very quickly.

Do not travel in icy or snowy weather unless your journey is essential. Drive extremely carefully when roads are or may be icy. Stopping distances can be ten times greater than on dry roads.

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.

If you’re driving behind other traffic on the motorway at night, use dipped headlights. Main-beam headlights will dazzle the other drivers. Your headlights’ dipped beam should fall short of the vehicle in front.

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.

You will feel the effect of engine braking when you take your foot off the accelerator. Changing to a lower gear will increase the effect.

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.

Rear fog lights make it easier to spot a vehicle ahead in foggy conditions. Avoid the temptation to use other vehicles' lights as a guide, as they may give you a false sense of security.

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.

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.

You must turn off your fog lights if visibility is more than 100 metres (328 feet). Be prepared for the fact that the fog may be patchy and you may need to turn them on again if the fog returns.

If your rear fog lights are left on when it’s not foggy, the glare they cause makes it difficult for road users behind to know whether you’re braking or you’ve just forgotten to turn off your rear fog lights. This can be a particular problem on wet roads and on motorways. If you leave your rear fog lights on at night, road users behind you are likely to be dazzled and this could put them at risk.

Holding the clutch down or staying in neutral for too long will cause your vehicle to freewheel. This is known as 'coasting' and it's dangerous because it reduces your control of the vehicle.

Coasting is when you allow the vehicle to freewheel in neutral or with the clutch pedal depressed. When travelling downhill, this will cause the vehicle to gain speed more quickly as you lose the benefits of engine braking; it may even lead to a loss of control. You should not coast, especially when approaching hazards such as junctions or bends and when travelling downhill.

In normal conditions, a ford can be crossed quite safely by driving through it slowly. The water may affect your brakes, so when you're clear of the ford, test them before you resume normal driving.

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.

You must use dipped headlights when daytime visibility is seriously reduced, generally to 100 metres (328 feet) or less. You may also use front or rear fog lights, but they must be switched off when visibility improves.

Traffic-calming measures are designed to protect vulnerable road users. Keep your speed down where traffic-calming measures are in place.
