Any issues deemed 'Dangerous' will earn an automatic fail

Changes are going to be made to MOTs which will be much harder on faulty vehicles (especially diesel users).

As of 20 May this year, vehicle faults will be graded according to three categories: ‘Minor’ problems which do little impact on either the vehicle’s safety or its environmental impact, ‘Major’ ones that have more of an impact and cause the vehicle to put other drivers at risk and ‘Dangerous’ issues that result in an automatic fail. Other grades will simply be recorded.

Some of the problems that can get your car or van banned from the road include:

  • A vehicle with a diesel particulate filter emitting coloured smoke

  • Diesel particulate filters which have been tampered with or taken out (unless you can be prove that this was done to clean it)

In contrast, a bit of leaking oil from a steering box would only get you marked with a minor fault.

Speaking to Auto Express, the head of MOT policy for the Driver and Vehicle Standards Agency said: “We’re changing the wording on the certificate. We’ve done a lot of research with motorists to find out what sort of information helps.”

Indeed, he said the organisation was simply designed to “help motorists do the right thing.”


A spokesperson of automotive services company RAC said: "Rather than MOT failures simply being black and white, the new system creates the potential for confusion as testers will have to make a judgement as to whether faults are Dangerous, Major or Minor.

"Motorists may also struggle to tell the difference."
