The wheels of a bicycle can become stuck in tram rails, causing the cyclist to stop suddenly, wobble or fall off. Tram rails also offer less grip than the road surface. This could cause a cyclist to skid, especially when it's wet.

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're following a cyclist who's signalling to turn right at a roundabout, leave plenty of room. Give them space and time to get into the correct lane.

If you're waiting to emerge from a side road, watch out for motorcycles. They're narrower than cars and can be difficult to see. Be especially careful if there are parked vehicles restricting your view. A motorcycle might be approaching. If you don't know, don't go.

A long vehicle, such as a lorry, a coach or a vehicle towing a trailer, may swing out to the right as it approaches a left turn. This allows the rear wheels to clear the kerb. Don't try to filter through if you see a gap on the nearside.

Where street repairs have closed off pavements, proceed carefully and slowly, as pedestrians might have to walk in the road.

If your view of the road ahead is restricted because you're being dazzled by approaching headlights, slow down and, if you need to, stop.

Should the parking brake fail, the use of first gear will help to prevent the vehicle from rolling backwards. By turning the front wheels to the right, they'll travel the shortest distance before running against the kerb. This will reduce the potential for the vehicle to move any further.

Reverse or parallel parking on the side of the road is a skill you need to learn as you prepare for your practical driving test. It will also help you to park safely and conveniently throughout your driving career. Once mastered, you should be able to park between two vehicles in a gap that would normally be about one-and-a-half times the length of your own vehicle.

You need to understand how your headlights are designed to operate. The main beam is aimed far ahead and to the left, while the dipped beam is aimed a short distance ahead and to the left. On the road, this means that on left-hand bends your headlights are aimed directly at the approaching driver, so you need to dip early to avoid dazzling them. Similarly, if you stop on the offside at night, even your dipped beam will dazzle oncoming drivers, as it's now aimed directly at them; using parking lights will avoid any dazzle.

Usually, a road is constructed with a camber: the road surface slopes to assist with drainage. Some bends have an 'adverse camber'. This is where the road slopes towards the outside of the bend. When going around a bend that has adverse camber, you need to take extra care. The forces acting on your vehicle could cause it to leave the road more easily than normal.

The right-hand lane of the motorway is for overtaking. Once overtaking is completed, you should return to the lane on your left. Sometimes you may be directed into a right-hand lane as a result of roadworks or an incident. This will be indicated by signs or officers directing the traffic.

When you're overtaking on a motorway, you'll sometimes find faster vehicles approaching from behind. When it's safe to do so, you should move over and let them pass. Don't try to enforce the legal speed limit.

Horses can be startled by the sound of a car engine or the rush of air caused by a vehicle passing too closely. Keep well back and only pass when it's safe. Leave them plenty of room. You may have to use the other side of the road to go past. If you do, first make sure there's no oncoming traffic.

Many towns have speed humps to slow traffic. They're often found where there are pedestrians. Slow down when driving over them and look out for pedestrians. If you drive too fast over a speed hump, you risk damaging your vehicle.

If you can't restart your engine before the warning bells ring, stay calm, especially if you have passengers on board. Leave the vehicle and get yourself and any passengers well clear of the crossing without delay.

If your vehicle breaks down on a level crossing, your priority is to get everyone out of the vehicle and clear of the crossing. If there's a railway telephone, use it to tell the signal operator what's happened. If you have time before a train arrives, move the vehicle clear of the crossing, but don't attempt this if the crossing alarm sounds.

When a driver is following you too closely, gradually increase the gap between your vehicle and the one in front. This will create a buffer, giving you more time to react if traffic suddenly slows down or stops.

By keeping well back from the large vehicle, you'll increase your view past it. This will allow you to see further down the road and be prepared for any hazards.

Engines are least efficient when they're cold; they take a few minutes to reach their operating temperature. Similarly, the catalytic converter needs to heat up before it operates efficiently. So, on short journeys, the vehicle will use more fuel and release more harmful exhaust gases into the environment. It may be quicker - and better for your health - to walk or use a bicycle.

If a motorcyclist has been injured, it's important not to remove their helmet unless it's absolutely essential to keep them alive.

If possible, lay the casualty down. Once you're sure there are no objects in the wound, apply firm pressure using clean material. Raising the arm above the level of the heart will also help to stem the flow of blood.

Lorry drivers may be unaware of objects falling from their vehicle. If you see this happen, and the lorry doesn't stop, drive safely onto the hard shoulder near an emergency telephone. Report the hazard to the authorities. Don't try to retrieve fallen items yourself.

As you approach a left turn, maintain your normal driving position on the left. Don't swing out before you turn, and make sure that you've reduced your speed and are in the correct gear. Look into the road before you turn and give way to any pedestrians who are crossing.

Large, long and heavy vehicles will need more time to pass you than a car, especially uphill. If necessary, be prepared to slow down to let them pass.
