Subject to the candidate's permission, instructors are encouraged to accompany their pupils on their driving test and also to listen to the examiner's debrief. If they haven't been present during the test, instructors are advised to be available to listen to the examiner's debrief at the end of the test.

Anyone who accompanies a learner driver on a driving test must be at least 16 years old and must wear a seat belt. (This includes a person who holds a seat-belt exemption certificate.) The accompanying driver mustn't take any part in the test. The examiner can end the test if they feel any inappropriate communication has taken place.

A new driver must hold a valid provisional driving licence before they drive on the road. When they receive their licence, they should check that the details are correct.

You mustn't sound your vehicle's horn in a built-up area while stationary on the road, or between the hours of 11.30 pm and 7.00 am. The exception is if another road user poses a danger.

It's advisable to use headlights when visibility is poor, but they must be used when visibility is seriously reduced. This is generally when you can't see more than 100 metres (328 feet). Front and rear fog lights may also be used, but you must switch them off again when visibility improves.

Cars, light goods vehicles, invalid carriages and motorcycles can be parked at night without lights on roads with a speed limit of 30 mph or less. They must comply with any parking restrictions and face the direction of the traffic flow.

Always switch off the engine, remove the key and lock your car, even if you're only leaving it for a few minutes.

When driving a motor car, a learner driver who holds a provisional driving licence must
- display red L plates (or D plates in Wales) to the front and rear of the vehicle
- be insured to drive the vehicle
- be accompanied by someone who's at least 21 years old and who has held for at least three years (and still holds) a full licence for the category of vehicle being driven.

If you aren't sure of the speed limit, a good indication is the presence of street lights. If there's street lighting, the speed limit will usually be 30 mph unless otherwise indicated.

If you wish to carry a heavy load on your vehicle, it's your responsibility to ensure that the load is secure and the vehicle isn't overloaded.

A new car in Great Britain doesn't require an MOT test certificate until it's three years old. At all times, it's the driver's responsibility to ensure that the vehicle they're driving is roadworthy.

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.

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.

The lowest level of insurance cover you must have to drive on public roads is third-party liability. The third party is anyone you might injure or whose property you might damage. With this minimum level of insurance cover, you're not covered for any damage to your vehicle or injury to yourself.

Only use front fog lights when adverse weather conditions mean you can't see more than 100 metres (328 feet). Remember: to avoid dazzling other drivers, turn off your fog lights when the visibility improves.

If you don't switch off rear fog lights when the fog has lifted, drivers behind may find it difficult to see your brake lights. This can be a particular problem on wet roads and on motorways. If you leave your rear fog lights on at night, drivers behind are likely to be dazzled and this could put you both at risk.

Passengers over 14 years old are responsible for wearing a seat belt when travelling in a vehicle, unless they're exempt. A responsible driver will make sure that passengers have fastened their seat belts before setting off.

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.

An MOT certificate will normally be valid for one year. The certificate doesn't warrant the condition of the vehicle at a later date, but simply shows that at the time the certificate was issued the vehicle met the MOT requirements. It's the driver's responsibility to ensure that the vehicle is roadworthy whenever it's driven.

Parking near a pedestrian crossing creates an obstruction that prevents both drivers and pedestrians from having a clear view. Careless parking is selfish and could endanger other road users.
