MOT Changes - 20 May 2018

On 20th May 2018, the rules of a Class 4 MOT test will change, introducing new defect types, stricter emission rules and exemption for some older cars. These changes will affect cars, motorcycles and light passenger vehicles.

The main 5 changes you need to know are:


Defects will be categorised differently - Currently any defects found during an MOT are classified under 'Fail' or 'Advisory'. This will change to:

Item ResultWhat It MeansAffect On Your MOT

FAIL

Stricter Rules For Diesel Car Emissions

There will be stricter limits for the emissions produced by diesel cars with a 'Diesel Particulate Filter' (DPF). A DPF is a filter in the exhaust system designed to reduce the amount of soot and carbon produced by a diesel car through filtering the exhaust gasses before releasing them into the atmosphere. Your vehicle will receive a 'Major Fault' if the MOT tester:

  • can see smoke of any colour coming from the exhaust
  • finds evidence that the DPF has been tampered with or removed

​Some New Things Will Be Included In The MOT

Some new items will be tested during the MOT. They include checking:

  • if tyres are obviously underinflated
  • if the brake fluid is contaminated
  • for fluid leaks posing an environmental risk
  • brake pad warning lights and if brake pads or discs are missing
  • reversing lights on vehicles first used from 1st September 2009
  • headlight washers on vehicles first used from 1st September 2009 (if they have them)
  • daytime running lights on vehicles first used from 1st March 2018(most of these vehicles will have their first MOT in 2021 when they're 3 years old)

There will be other smaller changes to how some items are checked. Your MOT test technician will be able to explain these to you if required.

​The MOT Test Certificate Will Change

The design of the MOT test certificate will also change. It will list any defects under the new categories, so they're clear and easy to understand. The DVSA service to check the MOT history of a vehicle will also be updated to reflect the new changes.

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 are over 40 years old and have not been substantially changed.

At the moment, only vehicles first built before 1960 are exempt from needing an MOT.

When the rules change on 20th May 2018, vehicles won't need an MOT from the 40th anniversary of when they were registered. You can check the date your vehicle was first registered on your V5/C certificate or alternatively by checking online.

Example if a car was first registered on 31st May 1978, it won't need an MOT from 31st May 2018

You will not have to apply to stop getting an MOT in your vehicle. However each time you tax your historic vehicle (even if you do not pay a fee), you'll have to declare it meets the rules for not requiring an MOT.

More Information

Our MOT costs will not change as part of the new regulations and the maximum amount an MOT centre can charge will not increase.

In January 2018, the government decided to keep the age a vehicle needs its first MOT at 3 years rather than extending it to 4 years.

Warning: You can be fined up to £1,000 and your insurance may be void if you drive without a valid MOT.
