New MOT Test Requirements 2018

So, what changes are now in place for the new MOT test?

In a nutshell, it’s a change to the categorisation of MOT failures as opposed to the actual test, from May 20th 2018, the categories will be ‘Dangerous,’ ‘Major’ and ‘Minor.’ Making the test far less black and white, i.e. pass or fail. Further to this, there will be far tougher emission tests for diesel cars and ‘smoke viability’.

Which Cars Are Most Likely to Be Affected?

It would appear that the new test regulations scrutinise diesel cars and punish their owners in particular. The new test regulations say that any car fitted with a diesel particulate filter (DPF) which emits ‘visible smoke of any colour’ during a metered test will get a major fault. This results in an automatic failure.

It is worth noting that MOT testers are being trained and instructed to check to see if DPFs have been removed or tampered with in any way, and refuse to test those cars which have been. This is unless the owner can provide a legitimate reason why a DPF has been tampered with (for example cut open and rewelded to clean the filter).

This is a major change from current rules which state that only diesel cars which are missing their DPF completely should be refused a test.

The question is, would you know to check that if you were buying a second hand diesel car?

Common MOT Failures

Before you take your car for its annual MOT, it is important to check for anything that you know will be an instant MOT failure. To help you out, we have compiled a list of the top reasons why cars fail their MOT test.

  • Lamps, reflectors and electrical equipment is responsible for 17.8% percent of MOT failures, which amounts to four and a half million cars. The next time you’re driving at night and notice your lights aren’t as bright as they once were, it may be time to replace the bulbs.


  • Suspension failure is a big one, at 12.1%. In fact, over the last two years, suspension failure has moved up from eighth most common reason, to second. Be it down to the increased weight of the vehicle, or firmer suspension of sports cars.


  • Without question, brakes are one of the most important parts of your car. It is alarming to discover just how many cars fail now as a result of worn out brake pads, or cable problems.


  • The condition of your tyres is another reason why so many cars fail their MOT. With the infamous British weather, it is very important to check that your tyres are in good working condition.


  • Worn out wipers and cracks in the windscreen impair a drivers vision and are therefore responsible for many MOT failures.
