Check your vehicle is safe to drive
You’re responsible for making sure your vehicle is always safe to drive (‘roadworthy’). It can be unsafe even if you have a current MOT certificate.
There are different rules for commercial vehicles.
Checks you should carry out
Every time you drive you should check:
- the windscreen, windows and mirrors are clean
- all lights work
- the brakes work
Your vehicle’s handbook will tell you how often to check the:
- engine oil
- water level in the radiator or expansion tank
- brake fluid level
- windscreen and rear window washer bottles – top up with windscreen washer fluid if necessary
- tyres – they must have the correct tread depth and be free of cuts and defects
The handbook will also tell you when your vehicle needs to be serviced.
Tread must be a certain depth depending on the type of vehicle:
- cars, light vans and light trailers – 1.6 millimetres (mm)
- motorcycles, large vehicles and passenger-carrying vehicles – 1mm
Mopeds only need to have visible tread.
There must be tread across the middle three-quarters and around the entire tyre.
