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.

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.

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.

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.

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.

Your safety and that of others may depend on the condition of your tyres. You must check that they're correctly inflated and have sufficient tread depth. The legal minimum tread depth 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.

Vehicles that require an MOT certificate mustn't be driven on the road after the certificate has expired. Exceptionally, the vehicle may be driven to and from a pre-arranged MOT test appointment or to a garage for repairs required for the test.

Child passengers should be encouraged to fasten their seat belts themselves from an early age, so that it becomes a matter of routine. It's the driver's responsibility to check that the seat belts of any passengers under 14 years old are fastened securely.

Driving a vehicle without insurance cover is illegal. If you cause injury to anyone or damage their property, it could be very expensive and you could also be subject to criminal prosecution.

It's illegal to use a mobile phone while you're driving (except for genuine emergencies). Driving requires your total attention and concentration at all times. Using a mobile phone will distract you and increase your chances of having a collision. Even using a hands-free system will distract you. Be safe: switch off your phone before you start driving and pick up any messages when you stop for a break.

Fog lights should only be used when visibility is seriously reduced. They must be switched off when visibility improves, to avoid dazzling other road users.

Drivers must be able to read a modern vehicle number plate from a distance of 20 metres. If you need glasses to do this, then you must wear them at all times when you're driving.

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.

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.

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.

It's illegal to use a hand-held mobile phone while driving, except in a genuine emergency. Make sure you park in a safe and convenient place before receiving or making a call or text message.

If you're involved in a collision that causes damage or injury to any other person, vehicle, animal or property, you must stop and exchange details with anyone having reasonable grounds for requiring them. If you don't give your details at the time, report the incident to the police as soon as is reasonably practicable and in any case within 24 hours.

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.

You must be medically fit to drive. All issues relating to alcohol, drugs or health have to be reported to the DVLA Drivers Medical Group or, in Northern Ireland, the DVA Drivers Medical Section. If a licence is revoked for any health-related reason, you must reapply to the relevant medical branch and satisfy them that you're now fit to drive before they'll issue the appropriate licence for the category you require.

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.

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.

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.

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.

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.
