Move off slowly and test the brakes and steering before driving in traffic.

It is an offence, as with faulty headlamps, brake lights, indicators or reflectors.

Clean number plates, tyres, all lights, clean windscreens and mirrors, leaks under the vehicle, warning lights and gauges, and the brakes and steering as you move off.

Safer and less likely to break down.

When the tread is less than 1.6 mm deep.

Do not drive. Have the vehicle checked by a mechanic first.
