It must be appreciated that the examiner's decision can't be changed. However, if the candidate believes that the test wasn't conducted properly, they have the right to appeal to the Magistrates' Court in England and Wales or the Sheriff's Court in Scotland.

A candidate must be able to read a modern-style number plate (made after 1 September 2001) from 20 metres. If the candidate's eyesight isn't up to the required standard, the test will go no further and they'll have failed.

Any more weight than this will take the vehicle into a different category, therefore making it unsuitable for a category B driving test.

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.

Anyone supervising a learner driver must be at least 21 years old and must have held (and still hold) a full licence for the category of vehicle being driven for at least three years.

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.

Special rules apply to drivers within two years of the date of passing their first driving test. If the number of penalty points on their licence reaches six or more as a result of offences they commit before the two years are up (including any points they acquired before passing their test), their licence will be revoked. If that happens, they must start again from the beginning: apply for a provisional licence and go through the qualifying process as a learner driver, with all that this entails.

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.

Car tyres must
- be correctly inflated
- have a tread depth of at least 1.6 mm across the central three-quarters of the breadth of the tread and around the entire circumference
- be free from certain cuts and other defects.
When checking tyres for cuts and bulges in the side walls, don't forget to check the inner walls (that is, those facing each other under the vehicle).

You must inform the Driver and Vehicle Licensing Agency (DVLA), or the Driver and Vehicle Agency (DVA) in Northern Ireland, about any health condition likely to affect your driving. They'll investigate your condition and how it affects your ability to drive; they may not take away your licence.

If someone fails their driving test, the examiner will give them a copy of the driving-test report form. This will show all the faults marked during the test. The examiner will also offer an oral explanation as to why they haven't passed. If the instructor is present during the examiner's explanation, they'll be able to offer their pupil additional advice and guidance.

The driver must ensure that all passengers under 14 years of age wear a seat belt or sit in an approved child restraint. A child under 3 years of age, who's travelling in the front seat of a car, must use an approved child restraint.

Photocard licences are valid for a maximum of 10 years. This is to allow the photographic likeness to be updated when the licence is renewed. However, the licence entitlement usually lasts until age 70.

It's the driver's legal responsibility to ensure that all passengers under 14 years old wear a seat belt, or are fastened in an approved child restraint. However, it's good practice to ensure that all other passengers wear seat belts as well.

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.

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.

All vehicles must display parking lights when parked on a road with a speed limit greater than 30 mph. Park in the direction of the traffic flow so that your parked vehicle isn't mistaken for a moving vehicle.

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.
