To make it easy to recognise, the 'stop' sign is the only sign that's octagonal. The visibility from a junction where the 'stop' sign is used will be poor, even from the edge of the junction. You must stop and, if necessary, edge forward until you can see it's safe to drive out.

Cyclists approaching a roundabout in the left-hand lane may be turning right, but may not have been able to get into the correct lane due to heavy traffic. They may feel safer by keeping to the left all the way around the roundabout. Give them plenty of room and be prepared for them to take a different course to other traffic.

At a roundabout, a horse rider wanting to turn right may feel safer keeping to the left all the way around the roundabout. Stay well back. Driving close behind or alongside could frighten the horse.

The purpose of this road marking is to keep the junction clear of queuing traffic. You may only wait in the marked area when you're turning right and your exit lane is clear but you can't complete the turn because of oncoming traffic.

The interior mirror of most vehicles can be set to the anti-dazzle position. You'll still be able to see the lights of the traffic behind you, but the dazzle will be greatly reduced.

If your indicators don't turn off automatically, you must cancel them. This might happen after a slight deviation, where the movement of the steering wheel hasn't been enough to activate the auto-cancel mechanism. A signal that continues to show after it should have cancelled can mislead other road users.

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.

Reflective studs on the motorway are there to help you in poor visibility. Different colours are used so that you'll know which lane you're in. These are
- red on the left-hand side of the road
- white between lanes
- amber on the right-hand edge of the carriageway
- green between the carriageway and slip roads.

You mustn't park in spaces designated or marked for specific users, such as registered disabled drivers (whose vehicle will display a blue disabled badge), or in places reserved for local residents.

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.

The motorcyclist is in a vulnerable position, exposed to further danger from traffic. You need to warn approaching traffic without putting yourself or anyone else at risk. Use your hazard warning lights and, if you have one, a warning triangle to alert other road users.

Wet roads will reduce your tyres' grip on the road. The safe separation gap of at least two seconds in dry conditions should be doubled in wet weather.

A candidate should tell DVSA of any special needs or circumstances when they book their driving test. No matter how serious the disability might be, the candidate will still take the same driving test as any other person. However, more time is allowed for the examiner to discuss the candidate's needs and talk about any adaptations fitted to the vehicle.

On a windy day, the blustery conditions will affect motorcyclists and they may be blown off course. If you wish to overtake a motorcyclist in these conditions, make allowances for them and give them extra room.

Learning is far more effective when a pupil can identify for themselves the reason why something has gone wrong. If they can't work it out, you can help them to understand with an explanation or a diagram. When they understand the problem, the pupil should then practise this manoeuvre.

Don't travel unless you really have to. Making unnecessary journeys will increase the risk of being involved in an incident. If you do decide to use your car, it's important that you can see and be seen. Make sure any snow or ice is cleared from lights, mirrors, number plates and windows.

Selecting a low gear when travelling downhill will help you to control your speed. The engine will assist the brakes and help prevent your vehicle from gathering speed.

Some bus lanes only operate during peak hours and other vehicles may use them outside these hours. Make sure you check the sign for the hours of operation before driving in a bus lane. Where no hours are shown, the bus lane operates 24 hours a day.

A driver who's been drinking alcohol should go home by public transport or taxi. Alcohol takes time to leave the body and someone might remain unfit to drive even the day after drinking it.

Potential driving instructors (PDIs) will have their eyesight tested at the start of their Part 2 examination. A number plate, where the letters and figures are 79 mm tall and 50 mm wide, must be read at a minimum distance of 26.5 metres (87 feet). If a PDI can't pass this test, their Part 2 examination will go no further. This won't, however, affect their licence to drive, as the ADI eyesight test standard exceeds the legal eyesight requirement.

If you're turning into a side road, pedestrians already crossing the road have priority and you should give way to them. Don't
-wave them across the road
-sound your horn
-flash your headlights
-give any other misleading signal - other road users may misinterpret your signal and you might lead the pedestrian into a dangerous situation.
If a pedestrian is slow or indecisive, be patient and wait. Don't hurry them across by revving your engine.

Some vehicles are prohibited from using the motorway. These include motorcycles under 50 cc, cyclists, horse riders, agricultural vehicles and powered wheelchairs/mobility scooters.

A red cross with flashing red lights above your lane shows that your lane is closed. You should move into another lane as soon as you can do so safely. If the signal shows above all lanes, you must stop and not go beyond the signal.

Before stopping, check the mirrors to see what's happening behind you. Also assess what's ahead and make sure you give the correct signal if it will help other road users. If you have to stop in an emergency, you may not always have time to use the mirrors.

Sometimes an insurance company will issue a temporary insurance certificate called a cover note. It gives you the same insurance cover as your certificate, but lasts for a limited period, usually one month.

Following too closely behind another vehicle at night may dazzle the driver. If you drop back, your headlight beam will fall short of the vehicle and so avoid dazzle.

On a quiet country road, always be aware that there may be a hazard just around the next bend, such as a slow-moving vehicle or pedestrians. Pedestrians are advised to walk on the right-hand side of the road if there's no pavement, so they may be walking towards you on your side of the road.

On a motorway, you should keep to the left-hand lane whenever possible. Only use the other lanes for overtaking or when directed by signals. Using other lanes when the left-hand lane is empty can frustrate drivers behind you.

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 convex mirror gives a wide view of the scene behind. However, it won't show you everything behind, or to the side of, your vehicle. Before you move off, look over your shoulder to check for anything that's not visible in the mirrors.
