Red rear reflectors show up when headlights shine on them. These are useful when you're parked at night but will only reflect if you park in the same direction as the traffic flow. Normally you should park on the left, but if you're in a one-way street you may also park on the right-hand side.

If your vehicle is stationary, only sound the horn if you think there's a risk of danger. Don't use it to attract attention. This causes unnecessary noise and could be misleading to other road users.

Anyone who accompanies a learner car driver must hold a full EC/EEA licence for the category of vehicle being driven, and they must have held it for at least 3 years. They must also be at least 21 years old. This applies even if they're just helping a friend and no money is exchanged.

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.

Double white lines along the centre of the road are usually found in places where there's a poor view ahead, usually caused by bends in the road. When the line nearest to you is solid, you may cross it to pass a stationary vehicle, providing that it's safe to do so.

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.

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.

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.

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.

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.

Only use front fog lights when adverse weather conditions mean you can't see more than 100 metres (328 feet). Remember: to avoid dazzling other drivers, turn off your fog lights when the visibility improves.

Special rules apply to drivers within two years of the date of passing their first driving test. If the number of penalty points on their licence reaches six or more as a result of offences they commit before the two years are up (including any points they acquired before passing their test), their licence will be revoked. If that happens, they must start again from the beginning: apply for a provisional licence and go through the qualifying process as a learner driver, with all that this entails.

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.

You mustn't sound your vehicle's horn in a built-up area while stationary on the road, or between the hours of 11.30 pm and 7.00 am. The exception is if another road user poses a danger.

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.

A candidate should tell DVSA of any special needs or circumstances when they book their driving test. No matter how serious the disability might be, the candidate will still take the same driving test as any other person. However, more time is allowed for the examiner to discuss the candidate's needs and talk about any adaptations fitted to the vehicle.

Any more weight than this will take the vehicle into a different category, therefore making it unsuitable for a category B driving test.

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.

At a ford, the road passes through a stream at a place where the water is normally shallow. When you've gone through the water, you should test your brakes and if necessary dry them out. To do this, first check that you won't cause danger to traffic behind. Then apply a light brake pressure while moving slowly. Make sure your brakes are working properly before resuming normal driving.
