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.

All motor vehicles are fitted with a horn; its purpose is to warn other road users of the vehicle's presence. You mustn't sound the horn between 11.30 pm and 7.00 am in a built-up area or when you're stationary, except when another road user poses a danger.

Check the vehicle handbook: this should give you guidance on the correct tyre pressures for your vehicle. There may be recommendations to increase the tyre pressure when carrying heavy loads or when travelling continuously at higher speeds, such as when using a motorway.

The lane under a gantry signal showing a red cross with flashing red lights is closed to traffic. You shouldn't proceed past that point in that lane. Should other lanes be open, move to a different lane and proceed with care. If red signals are shown above all lanes, then all lanes are closed: you must stop and wait for the lights to change or until you're directed to move.

When traffic lights are out of order, you should treat the junction as an unmarked crossroads. Be cautious, as you may need to give way or stop. Keep a lookout for traffic attempting to cross the junction at speed.

Large goods vehicles are fitted with speed limiters. This means it can take them a long time to overtake if the vehicle they're passing is travelling close to their limited speed. If a lorry is struggling to overtake you, slow down to let it pass. This helps the lorry driver and also other drivers following behind who want to travel faster.

Black ice makes a road look damp, and you may not be able to see that it's icy. Signs that indicate you may be on black ice include
- your steering suddenly feels light
- a lack of road noise from your tyres.

Questions that require a simple 'yes' or 'no' are of limited value. To be effective, you should ask searching questions based on 'what', 'when', 'where', 'why' and 'how'. The power of effective questioning as an aid to learning is sometimes overlooked; it can help to motivate pupils.

You should always give cyclists plenty of room when you're overtaking them. When it's windy, you need to allow enough room in case a sudden gust blows them off course and into your path.

Alcohol remains in the body for several hours; this may make you unfit to drive a long time after having an alcoholic drink. If you know you'll be driving, the safest course is to avoid drinking any alcohol.

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.

Compulsory reduced speed limits are often in force throughout roadworks on the motorway. This safety measure is to protect drivers and workers in the road. Be aware of reduced speed limits and slow down in good time.

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.

The brakes on your vehicle must be effective and properly adjusted. If your vehicle pulls to one side when braking, take it to be checked by a qualified mechanic. Don't take risks.

Check there are no objects in the wound and then apply a firm pressure with a pad of clean material, such as a bandage or a length of cloth. Raising the leg will lessen the flow of blood. Avoid tying anything tightly round the leg, as any restriction to blood circulation for more than a short period of time can result in long-term injury.

If a serious incident occurs that requires you to use the dual controls, it's vital that the pupil fully understands what happened and how they could have avoided the situation or dealt with it better.

At the correct stage in a pupil's development, it's beneficial to practise steering the vehicle with one hand. They should then find it easier to change gear, operate another control or give arm signals as and when appropriate. Any tendency to drive with one hand without good reason should be strongly discouraged.

You can move into a box junction as long as your exit road is clear. You can stop and wait in the junction when you want to turn right and have to wait for a gap in the oncoming traffic.

When coasting, the engine is disconnected from the drive to the wheels. This means that the engine's resistance can't be used to help slow the vehicle, especially when travelling downhill. There will be a little coasting every time you change gear; this can't be avoided, but it should be kept to a minimum.

The lights that control the crossing show to both directions of traffic. If a pedestrian from either side is still crossing when the amber light is flashing, you must wait.

The details on your motor insurance certificate show who, when and what's insured. You'll have to produce the certificate if you've been involved in an incident and when requested by the police.

Always carry an advance warning triangle, or other permitted warning device, in your vehicle. Use it to warn other road users if your vehicle has broken down or there's been an incident. You're advised to place it about 45 metres (147 feet) behind the vehicle, on the same side of the road. You may need to place it further back if the vehicle is hidden by, for example, a bend, hill or dip in the road. Never attempt to place any warning device on a motorway.

In some built-up areas, the speed limit may be reduced to 20 mph. Where there are traffic-calming features, the speed limit may be signed as a 20 mph zone with no repeater signs within the zone. Where there are no traffic-calming features, the 20 mph speed limit is signed at each end of the street and with repeater signs in between. Driving at a slower speed will help give you the time and space to see and deal safely with hazards such as pedestrians and parked cars.

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.

When teaching your pupil the turn-in-the-road exercise, you should explain that having the car under control is only part of the procedure. They also need to be aware of other road users and know how to deal with them safely.

At blind junctions, there's often a 'stop' sign. The 'stop' sign has been put there because the view into the main road is poor. You must stop because it won't be possible to assess the situation on the move, however slowly you're travelling.

If your vehicle is stationary, only sound the horn if you think there's a risk of danger. Don't use it to attract attention. This causes unnecessary noise and could be misleading to other road users.

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.

Strict controls on exhaust emissions require a catalytic converter to be fitted to the exhaust system of all new vehicles. Catalytic converters remove most of the carbon monoxide, oxides of nitrogen and unburned hydrocarbons from the exhaust gases.

At junctions where the view is restricted, you need to make sure your pupil has time to assess the situation. Teach them to approach slowly and get a good look at the traffic situation before making a decision.
