MOT Rule Changes: 20 May 2018 | Hughes Group

MOT Test Changes​

​As of Sunday 20th May 2018, there will be changes made to how the MOT Test is carried out. These changes include new defect types, stricter rules for diesel car emissions and some vehicles over 40 years old becoming exempt from the test.The changes will apply to England, Scotland and Wales and will affect cars, vans, motorcycles and other light passenger vehicles.​

5 Main Changes:

1) Defects are being categorised differently

- Dangerous
- Major
- Minor

The category given to each item will depend on the type of problem the vehicle has and how serious it is, advice will still be given for items you need to monitor - these are known as advisories.


New categories:

Item result What it means about the item How it affects your MOT result
Dangerous A direct and immediate risk to road safety or has a serious impact on the environment.

Do not drive the vehicle until it’s been repaired.
Fail
Major It may affect the vehicle’s safety, put other road users at risk or have an impact on the environment.

Repair it immediately.
Fail
Minor No significant effect on the safety of the vehicle or impact on the environment.

Repair as soon as possible.

2) Stricter rules for diesel car emissions

There will be stricter limits for emissions from diesel cars with a Diesel Particulate Filter (DPF). The DPF captures exhaust soot to reduce emissions from diesel cars.

You will get a major fault if your MOT tester...

- Can see smoke of any colour coming from the exhaust
- Finds evidence the DPF has been tampered with

3) New checks included in the MOT test

- if the tyres have been obviously underinflated
- if the brake fluid has been contaminated
- fluid leaks posing environmental risk
- brake pad warning lights and if the pads or disk are missing
- reversing lights in vehicles first used from 01/09/09
- headlight washers on vehicles first used from 01/09/09 (if they have them)
- daytime running lights on vehicles first used from 01/03/18 (most vehicles will have their first MOT in 2021 when they're 3 years old

4) Changes to the MOT Certificate

- the design
- it will list any defects under the new categories in a way that is clear and easy to understand
- service will be updated to check the MOT history of a vehicle to reflect the changes

5) Some vehicles over 40 years old won't need an MOT

- Cars, vans, motorcycles and other light passenger vehicles won't need to have an MOT if they're over 40 years old and have not been substantially changed
- Vehicles won't need an MOT from 40th anniversary of when they're registered
