There's an eyesight test for the Register of Approved Driving Instructors. The requirement is that an instructor must be able to read a number plate with letters and figures 79 mm high and 50 mm wide at a minimum distance of 26.5 metres (87 feet). This is a greater distance than the minimum legal requirement for car drivers.

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.

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

You must stop if you've been involved in a collision that results in any injury or damage. You must also be able to produce your driving licence when a police officer asks to see it. If you can't do this at the time, you may be asked to take it to a police station within a certain period. You may also be asked to show a valid insurance certificate and a valid MOT certificate.

Photocard licences have to be renewed every 10 years until the age of 70. This is to make sure that the photograph is a good likeness of the licence holder.

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.

Drivers mustn't park or drive in a cycle lane that's marked by a solid white line during its periods of operation. At other times, when the lane isn't in operation, you should be aware that there may be cyclists in the area.

The sign shows a mandatory cycle lane, and drivers mustn't park or drive in it during its times of operation. The lane will be marked by a solid white line on the road. Where the cycle lane is advisory, it will be marked by a broken white line. There'll also be a similar sign that shows a cycle on a blue background but without the lane represented. Don't drive in this lane unless it's unavoidable.

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.

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.

Where fitted, seat belts must be worn. It's the driver's responsibility to ensure that children under 14 years old wear a seat belt or use a suitable child restraint. Passengers aged 14 or over are responsible for wearing their seat belt. Exceptions to this law are made for people who hold a medical exemption certificate.

It's a requirement of the driving test that if a dual accelerator pedal is fitted to a vehicle, it must be removed before the test.

At the start of the practical driving test, the examiner will ask the candidate if they wish their instructor or accompanying driver to be present during the test. Anyone who does accompany the candidate must be 16 years or older and must wear a seat belt during the test.

Dual carriageways and motorways share the same 70 mph national speed limit for cars and motorcycles. If a car or motorcycle is towing a trailer, then this maximum permitted speed is reduced to 60 mph.

A person with only one eye isn't considered to have a disability for the purpose of driving and will be issued with an unrestricted driving licence.

Driving instructors who always display L plates on a training vehicle are exempt from having to remove them when a full licence holder is driving the car.

A category B driving entitlement is normally valid until a person's 70th birthday. The new photocard licence needs to be updated every 10 years; this is to keep the photograph up to date.

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.
