The colours of the reflective studs on the motorway, and their locations, are
- red - between the hard shoulder and the carriageway
- white - between the lanes
- amber - between the edge of the
carriageway and the central reservation
- green - along slip-road exits and entrances bright green/yellow - at roadworks and contraflow systems.

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

If an ADI is charging for a driving lesson, they must display their ADI certificate and appropriate L or D plates on the tuition car.

A skid happens when the driver changes the speed or direction of their vehicle so suddenly that the tyres can't keep their grip on the road. The risk of skidding is much greater on wet or icy roads than in dry conditions. It's the driver's responsibility to recognise the conditions and drive in a manner that takes the conditions into account.

Large vehicles can hide other vehicles that are overtaking, especially motorcycles. You need to be aware of the possibility of hidden vehicles and not assume that it's safe to emerge.

Before giving any signal, you need to use your mirrors to check what's behind and consider how other drivers may be affected by your signal. Sometimes a signal may not be necessary or you may feel it safer to give a signal earlier or later than normal.

Double white lines along the centre of the road are usually found in places where there's a poor view ahead, usually caused by bends in the road. When the line nearest to you is solid, you may cross it to pass a stationary vehicle, providing that it's safe to do so.

By leaving the car in gear, the engine will help to prevent the vehicle from rolling. When parking facing uphill, select first gear. This will maximise the resistance from the engine if the parking brake should fail.

An instructor must normally wear a seat belt during all practical training when there's one fitted to the vehicle, unless they're exempt. However, when a pupil is carrying out a manoeuvre that involves reversing, instructors may release the belt during the exercise; this gives them a little more freedom to teach the exercise safely.

If you follow another vehicle with your headlights on full beam, they could dazzle the driver. Leave a safe distance and ensure that the light from your dipped beam falls short of the vehicle in front.

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

Where a motorway has a steep uphill gradient, slow-moving, large vehicles might get in the way of other traffic. An extra lane on the left may be provided for these slow-moving vehicles. It allows faster-moving traffic to flow more easily.

Using a lower gear will allow the engine braking to assist the brakes in keeping the vehicle's speed under control. Avoid coasting with the clutch held down or rolling in neutral, as there will then be no engine braking.

Approved driving instructors and trainee driving instructors are issued with an identification certificate. This must be displayed on the windscreen of a vehicle that's being used for a driving lesson.

At a ford, the road passes through a stream at a place where the water is normally shallow. When you've gone through the water, you should test your brakes and if necessary dry them out. To do this, first check that you won't cause danger to traffic behind. Then apply a light brake pressure while moving slowly. Make sure your brakes are working properly before resuming normal driving.

When turning right from a side road across a dual carriageway, make sure that the central reservation is wide enough to contain your vehicle. If it isn't, you'll have to treat the dual carriageway as one road and only emerge when it's clear in both directions. Drivers of longer vehicles and vehicles towing trailers or caravans will need to assess this carefully. If any part of an emerging vehicle obstructs the right-hand lane of the dual carriageway, it could have serious consequences.

These lines are a device often found on the approach to a roundabout or a dangerous junction. They become closer together as you approach the hazard, warning you to slow down.

If you're travelling in a one-way street and wish to turn right, you should take up a position in the right-hand lane. This will enable other road users not wishing to turn to keep going on the left. Indicate your intention and take up your position in good time.

Sometimes road markings can be obscured by queuing traffic, or you may be unsure which lane you need to be in. If you realise too late that you're in the wrong lane, don't cut across lanes or bully other drivers to let you in. Follow the lane you're in and find somewhere safe to turn around if you need to.

By taking a position well to the left as you enter a right-hand bend, you'll improve your view around the bend. This will help you to see any hazards as soon as possible. Positioning well to the left also reduces the risk of collision with an oncoming vehicle that may have drifted over the centre line.

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.

Driving a vehicle without insurance cover is illegal. If you cause injury to anyone or damage their property, it could be very expensive and you could also be subject to criminal prosecution.

It's important that driving faults and errors are dealt with promptly. Learning will also be more effective if the pupil can spot their own errors and come up with their own strategies for ensuring the errors don't happen again. If the pupil doesn't recognise the fault, you'll need to tell them. Even then, the pupil can still work on developing strategies themselves.

All warning signs are triangular, but the 'give way' sign is the only triangular sign that points downwards; this is to give it greater prominence as you approach a junction. When you see this sign, you must give way to traffic on the road that you're about to join.

In queuing traffic, motorcyclists and cyclists often filter past the stationary vehicles. Before you turn right in a traffic queue, check your mirrors for passing vehicles. Motorcyclists and cyclists are smaller than other vehicles and can be difficult to see, so look for them before turning.

If you intend to overtake on a two-way road that has three lanes, you must consider that approaching traffic could be planning the same manoeuvre. When you've considered the situation and have decided it's safe, indicate your intentions early. This will show the approaching traffic that you intend to pull out. Some of these roads have solid white lines marked to allow for overtaking in one direction only, usually for uphill traffic.

If you brake while travelling in a straight line, the inertia of the vehicle tries to keep it moving forward. This moves the weight of the vehicle forward and onto the front wheels. This extra load on the front tyres will press them more firmly into contact with the road, giving more tyre grip.

When giving cardiopulmonary resuscitation (CPR), continue until the casualty is breathing unaided or until medical help arrives. Don't give up. Look for signs of recovery and check the casualty's pulse. Avoid moving them unless it's necessary for their safety.

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.

Turning the wheels to the left will ensure that if the vehicle rolls forward, it will immediately contact the kerb. The use of reverse gear will help by using the resistance of the engine to prevent the vehicle from rolling forwards should the parking brake fail.
