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.

If a disabled driver passes their driving test in a specifically adapted motor car, the driving licence issued will restrict them to driving vehicles fitted with the necessary adaptations.

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 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.

Drivers and passengers must normally wear seat belts. However, a driver may remove their seat belt when carrying out an exercise that involves reversing; this also applies to driving instructors while supervising such manoeuvres.

If you aren't sure of the speed limit, a good indication is the presence of street lights. If there's street lighting, the speed limit will usually be 30 mph unless otherwise indicated.

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.

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.

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.

If your vehicle requires an MOT certificate, it's illegal to drive it without one. As well as being illegal, the vehicle may be unsafe for use on the road and your insurance may be invalid.

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.

The sign shows a mandatory cycle lane, and drivers mustn't park or drive in it during its times of operation. The lane will be marked by a solid white line on the road. Where the cycle lane is advisory, it will be marked by a broken white line. There'll also be a similar sign that shows a cycle on a blue background but without the lane represented. Don't drive in this lane unless it's unavoidable.

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.

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.

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.

When a candidate passes a practical driving test, their full licence is normally issued directly by the licensing authority. However, if this doesn't happen, successful candidates should apply for a full licence as soon as possible. The driving-test pass certificate is valid for two years; if a full licence isn't applied for within that time, the driver will need to retake their 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.

If you want to turn left and there's a cyclist in front of you, hold back. Wait until the cyclist has passed the junction and then turn left behind them.
