In heavy rain, the road will be wet and there may be pooling surface water. This will reduce the grip the tyres have on the road and will at least double the distance it takes to stop. Take this increased stopping distance into account while driving. Double the separation distance you'd leave in dry conditions.

If you're towing a caravan or trailer, you mustn't use the right-hand lane on a motorway with three or more lanes, except in certain circumstances, such as when there are lane closures.

If your vehicle breaks down, be aware of the danger to, and from, other traffic. Get your vehicle off the road if possible. Use a warning triangle to alert other road users to the obstruction, unless you're on a motorway.

Although there will be times when it's necessary to check blind spots on the move, turning right around is unnecessary and could be dangerous. Regular and sensible use of the mirrors, with a quick sideways glance as necessary, will keep a driver up to date with what's happening all round.

Tyres won't grip the road surface so well in wet weather or on loose road surfaces. On wet roads, it's recommended that you allow at least double the stopping distance you would leave in dry conditions.

Sometimes, large vehicles may need more space than other road users. If a vehicle needs more time and space to turn, be prepared to stop and wait.

If you scan the road as you drive, you should see hazards developing. Once you've seen the danger, reduce speed and be prepared to stop if necessary.

If there's any doubt as to whether it's safe to reverse, get out and have a look before you start reversing.

In good conditions, one useful method of checking that you've allowed enough room between you and the vehicle in front is the two-second rule. To check for a two-second time gap, choose a stationary object ahead, such as a bridge or road sign. When the car in front passes the object, say, 'Only a fool breaks the two-second rule'. If you reach the object before you finish saying this, you're too close.

Normally, an overtaking manoeuvre is carried out by passing the slower vehicle on its right. However, on a congested motorway where traffic on your right is moving more slowly than you are, it's acceptable to continue in the same lane and pass vehicles on their left.

Some zebra crossings are divided by a central island. Each half is a separate crossing.

You must always remain within the speed limit, but how fast you drive will depend on many other factors. Above all, you should never drive so fast that you can't stop within the distance you can see to be clear.

On a three-lane motorway, you should travel in the left-hand lane unless you're overtaking. This applies regardless of the speed at which you're travelling.

Take care to understand what the approaching driver intends, as this may determine your approach. Turning behind the approaching vehicle, wherever possible, will ensure that your view of the road ahead isn't blocked. At some junctions, the layout may make it difficult to turn this way; if this is the case, be prepared to pass in front of the other vehicle. At some junctions, the lane markings direct you to turn this way.

There are marker posts at 100 metre intervals along the hard shoulder of a motorway. The markers direct you to the nearest emergency telephone, so follow them if you've broken down.

Never overtake unless you're absolutely sure that it's safe. Ask yourself, 'Can I see far enough down the road to complete the manoeuvre safely? Are there junctions ahead? Is it legal to overtake here?' If you have any doubt, then wait until you can overtake safely and legally.

Horse riders often keep to the outside of the roundabout even if they're turning right. Give them plenty of room and remember that they may have to cross lanes of traffic.

Signals should be cancelled soon after use. If a driver is unsure of the location of a junction or destination, they may signal earlier than normal while looking for their turn. Don't attempt to overtake, as they may turn suddenly.

If you want to turn left and there's a cyclist in front of you, hold back. Wait until the cyclist has passed the junction and then turn left behind them.

A toucan crossing is designed to allow pedestrians and cyclists to cross at the same time. Look out for cyclists approaching the crossing at speed.
