MOT testing rule change -May 2018

The 20th May 2018 sees the new MOT test changes come into practice. These changes include: tighter rules for diesel car emissions, new defect categories, and some vehicles over 40 years old being classified as exempt.

Cars, vans, motorcycles and other light passenger vehicles will all be affected by the implementation of the changes.

What you will need to know.

Defect Categories are changing

Defects revealed during the MOT will be categorised as follows :

  • Dangerous - Immediate risk - Fail
  • Major- May pose risk to road users, affect vehicle safety or the environment - Fail
  • Minor- No detectable safety effects of vehicle or impact on environment - Pass
  • Advisory- May become more serious in the future, monitor and repair - Pass
  • Pass- Meets minimum legal standard - Pass

The category provided by the MOT tester for each item depends on the individual problem and its seriousness.

MOT testers will continue to give advice to monitor items, these are known as ‘advisories’.

It is worth noting that all JCB Group Service Centres have always included free 'vehicle visual health checks' as part of the routine procedure on a vehicle visit to the workshop. We check a long list of components for roadworthiness and rate them by a traffic light system. We would not let you drive the vehicle away if there was a red light category defect.

Diesel vehicle emissions will now have stricter rules

Diesel car emissions with a diesel particulate filter (DPF) - which captures and stores exhaust soot reducing emissions from diesel cars - have tighter limits.

The MOT tester may give a major fault fail if :

  • They can see smoke of any colour coming from the exhaust
  • They find evidence that the DPF has been tampered with

Faulty Components to be included in the new MOT

  • Tyres that are under-inflated
  • Brake fluid that has been contaminated
  • Fluid leaks that pose an environmental risk
  • Brake pad warning lights and brake components that are missing : Pads or discs
  • Reversing lights on vehicles first used from 1 September 2009
  • Headlight washers on vehicles first used from 1 September 2009
  • Daytime running lights on vehicles first used from 1 March 2018

Vehicles over 40 years old will be exempt from an MOT

Currently, only vehicles built before 1960 are exempt from requiring an MOT. However, vehicles over 40 years old will not require an MOT from May 2018. These vehicles will not need an MOT from the 40th anniversary of when they were first registered.

Eg; A vehicle first registered on 31st May 1978, will not need an MOT from 31st May 2018.

Although, each time you tax your historic vehicle, even if you aren’t required to pay a fee, you will need to declare it meets the new rules for not requiring an MOT. There is no need to apply to stop getting an MOT for your vehicle.
