When a physically disabled driver passes their driving test in a specially adapted vehicle, the licence issued will include restrictions. These will require the necessary modifications to be fitted to any vehicle they drive.

Using a hand-held mobile phone while you're driving is illegal. Driving requires all of your attention, all of the time. Any distraction, however brief, is potentially dangerous and could affect your control of the vehicle. Even using a hands-free system will distract you. The only safe way is to switch your phone off and make or pick up calls when you stop for a rest break.

This is a method used by insurance companies to keep annual premiums down. When you agree to an excess, it means that, in the event of a claim, you'll pay the agreed amount before the benefits of the policy will apply. Generally, the higher the excess you choose to pay, the lower the annual premium you'll be charged.

To park at night without lights, you must comply with certain conditions. The road must be subject to a 30 mph speed limit, or less. Parking too close to a junction or facing the flow of traffic could confuse and cause danger for other road users.

You must be able to show your documents to a police officer when asked to do so. If you don't have them with you, you're allowed to produce them at a police station within seven days.

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.

Before taking a learner driver out for their first driving lesson, an approved driving instructor (ADI) or accompanying driver should first check the learner's
- eyesight meets the legal requirements
- driving licence is valid.

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.

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.

Bright fog lights can dazzle other drivers, so you must remember to turn them off when the fog lifts and visibility improves. Be prepared for patchy fog: you may need to turn the fog lights on again.

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.

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.

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.

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.

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.

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.

Exemptions are provided in the regulations. If an inertia-reel seat belt has temporarily locked because the vehicle is parked on a gradient, the driver may move the vehicle. As soon as the mechanism has unlocked and released itself, the driver should stop and apply the belt.

The Driver and Vehicle Standards Agency will need to know that your pupil is profoundly deaf to make the appropriate booking arrangements. This should be recorded when booking the test. Approved driving instructors should be able to help any pupil with their application for a theory test or a practical driving test.

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.

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.
