When renewing your vehicle tax, you must have valid insurance cover for the vehicle. It's illegal to drive or keep a vehicle on public roads without insurance cover.

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.

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

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.

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

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.

If a driver accumulates 12 or more penalty points within a three-year period, they must be disqualified. This will be for a minimum period of six months and may be longer if the driver has previously been disqualified.

For safety reasons, any dual accelerator must be removed before a vehicle can be used by a candidate for their driving test.

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.

When parking, all ancillary controls should be switched off and the engine stopped. Make sure that the handbrake is applied firmly before leaving the vehicle.

If you don't switch off rear fog lights when the fog has lifted, drivers behind may find it difficult to see your brake lights. This can be a particular problem on wet roads and on motorways. If you leave your rear fog lights on at night, drivers behind are likely to be dazzled and this could put you both at risk.

Alcohol remains in the body for several hours; this may make you unfit to drive a long time after having an alcoholic drink. If you know you'll be driving, the safest course is to avoid drinking any alcohol.

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.

Before you drive a vehicle on the road, you must hold a driving licence for the class of vehicle being driven. You must also be covered by a minimum of third-party insurance while driving that vehicle.

The national speed limit for a car or motorcycle on a single carriageway is 60 mph. You don't have to drive at the speed limit. Use your judgement and keep within the speed limit while driving at a speed that suits the road, weather and traffic conditions.

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.

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.

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.

The extended test takes about 70 minutes and is assessed to the same level as the standard driving test for learner drivers.

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.
