From 20 May, there will be some significant changes to MOT testing in the UK. Find out more here.

The new MOTs changes are now inforced as the Driver and Vehicle Standard Agency (DVSA) strives to provider cleaner and safer vehicles for our roads. Below we bring you a breakdown of what those changes look like and how they’ll affect you come your next test date.


Categorisation of issues


Arguably one of the most significant changes will be moving away from a simple pass or fail for a more detailed analysis.

There will now be five potential outcomes:

1. Pass – meets the legal requirement

2. Advisory – ok for now and passes the MOT, but something to keep an eye on

3. Minor – slight issue which needs to be fixed as soon as possible, but is not currently a risk to the driver, other road users or the environment, so the vehicle will pass the MOT

4. Major – this issue could be a risk to the driver, other road users and/or could impact the environment, causing the vehicle to fail the MOT. Needs fixing as a priority.

5. Dangerous – this issue is currently posing a risk to the driver, other road users and/or the environment so immediate fail. Vehicle must not be driven until the issue is resolved.

Clamping down on diesel

Following further controversy surrounding diesel, there will be stricter checks on a vehicle’s diesel particulate filter (DPF).

If the tester finds smoke of any colour coming from the exhaust or evidence that the filter has been tampered with, the vehicle will receive a major fault and therefore fail the MOT.

The history of the DPF

  • The filter prevents small particles of soot being expelled into the air
  • A clogged DPF can be costly to fix, which has led many diesel vehicle owners to tamper with or remove the filter altogether
  • Removing the DPF is illegal, as well as harmful for the environment
  • The stricter MOT element intends to eradicate this issue

Additional checks

There are some new checks that will be added to the standard test, including:

  • Level of tyre inflation
  • Contaminated brake fluid
  • Worn or absent brake pads
  • Reversing lights (on cars used from Sept ’09)

A new look certificate

Following the new test, the vehicle will receive a newly formatted certificate which will clearly outline any defects identified and which category they fall into.

The end of the MOT

Finally, cars vans and motorbikes registered over 40 years ago will no longer require the MOT test.


And that’s it! There’s no change to the process, how much garages can charge or how often your vehicle needs to be tested. The most important thing to remember is that the rules aren’t changing to catch us out, they’re changing to protect us, which can only be a good thing. Embrace the change for cleaner and safer roads.
