Free ADI Band 3 Theory Test

If your pupil's driving is below the required test standard, it's your responsibility as a professional instructor to advise them not to take the test. As soon as you become aware of a possible problem, you should discuss this with your pupil and positively encourage them that, in their interest, and for other road users as well, it would be far better to postpone the appointment. If you can't dissuade them, then you should withhold the use of your vehicle. Ultimately, it's the pupil's test and an instructor can't prevent them from taking it in someone else's vehicle.

Dual accelerators aren't normally fitted to training vehicles. If one is fitted, it must be removed while the vehicle is being used for a driving test.

Don't park less than 10 metres (32 feet) from a junction (unless in an authorised parking place). At night, park in the direction of the traffic, so that your car's red reflectors show to passing drivers. You must use your parking lights when parking at night on a road, or in a lay-by on a road, where the speed limit is over 30 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.

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.

A person who's colour-blind will have to take exactly the same practical driving test as any other candidate. No restriction will be placed on their driving licence when they pass their test.

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.

The maximum permitted speed for a car on a motorway is 70 mph, but if a car is towing a caravan or trailer, the speed limit is reduced to 60 mph. Also, vehicles towing trailers may not use the right-hand lane of a motorway that has more than two lanes.

Tyres must have enough depth of tread to give them a good grip on the road surface. The legal minimum for cars is 1.6 mm. This depth should be across the central three-quarters of the breadth of the tyre and around the entire circumference.

Fog lights will help others see you, but they must only be used if visibility is seriously reduced. You must turn fog lights off when visibility improves, to avoid dazzling other road users.

A pedestrian who's carrying a white cane with a red band or bands is both blind and deaf. This makes them very vulnerable, since they can neither see nor hear you approaching.

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.

If there are double white lines along the centre of the road and the line nearest you is continuous, you mustn't cross or straddle the line, except in specific circumstances. These include to enter premises or a side road, or to pass a stationary vehicle. You may also overtake a bicycle, horse, or road maintenance vehicle, provided they're travelling at 10 mph or less. You mustn't park on such a road, but you may stop to pick up or set down passengers.

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.

Anyone wishing to accompany 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.

An amber flashing light on a vehicle indicates that it's slow-moving. Mobility scooters used by disabled people are limited to no more than 8 mph. On dual carriageways, they must display an amber flashing light.

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

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.

When parking at night, park in the direction of the traffic flow. This will enable other road users to see the reflectors on the rear of your vehicle. You must also use parking lights where the speed limit is more than 30 mph.

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.
