MOT Test Rule Changes

Diesel vehicles are back in the spotlight again with new MOT test changes coming in this May!

It was announced yesterday that, from the 20th May 2018 in England, Scotland and Wales, MOT testers will now class faults under the new defect categories - Minor, Major, Dangerous, as well as Advisory and Pass.

MOT testers will still be able to offer 'advisories' for you to monitor any items that could potentially become a fault.

Any vehicles fitted with a Diesel Particular Filter (DPF) will have stricter limits for emission control. If the vehicle is seen to be showing any colour smoke from the exhaust or shows signs that the DPF has been tampered with, it will receive a major fault on the MOT test.

Emissions are the focus of an MOT test

There are other items that have been added to the MOT test checklist too, which include:

  • Tyres are obviously under-inflated.

  • Brake fluid has been contaminated.

  • Fluid leaks that can cause environmental risks.

  • Brake pad warning lights and brake pads or discs are missing.

Plus, vehicles registered after 1 September 2009 that were fitted with reversing lights and headlight washer by the manufacturer will have those tested during the MOT.

As well as this, vehicles registered after 1 March 2018 which were fitted with daytime running lights by the manufacturer will have those tested. The majority will have their first MOT when they are 3 years old, in 2021.

But, there is some exciting news, for older and classic vehicles!

From the 40th anniversary of when the vehicle was registered, it won't need an MOT. However, you will still need to declare that the vehicle meets the rules of no MOT when you tax the vehicle, even if you don’t pay for it.

Don't get caught and lose money!

So, make sure your vehicle meets and passes the new standards this year, as you could be fined up to £1,000 if you don’t have a valid MOT!
