What is the MOT test?

Currently in the UK, all cars over three-years-old must legally have an MOT test carried out every year by an approved testing centre.

The test checks the technical elements of your vehicle to make sure it’s safe to drive, and detects toxic emissions that could harm the environment.

The latest shake-up of the rules is designed to keep you and other road users safer, but many drivers are concerned about what the changes will actually mean.

How is the MOT changing?

There are five key changes you need to know about so you don’t get caught out:

1. Defects categorised differently

If a fault is found during your MOT, it will be categorised as either:

Dangerous (Fail)

Major (Fail)

Minor (Pass)

2. Stricter rules for diesel car emissions

Any car that has been fitted with a diesel particulate filter (DPF) that gives out "visible smoke of any colour" during testing will get a major fault – an automatic fail.

It will also fail if the MOT tester finds evidence that the DPF has been tampered with.

3. New items tested during the MOT

In addition to the current checks, new elements will be added to the testing procedure. These include checking whether:

• Tyres are obviously underinflated
• Brake fluid has been contaminated
• Fluid has leaked, posing an environmental risk
• Reversing lights on all vehicles are functional
• Brake pad warning lights are lit, and if brake pads or discs are missing
• Headlight washers on vehicles first used from 1 September 2009 (if they are fitted)
• Daytime running lights on vehicles first used from 1 March 2018 (majority of these vehicles will have their first MOT in 2021 when they’re 3 years old)

4. Change to appearance of MOT certificate

The design of the MOT certificate will look different. It will list any defects under the new categories, so they’re clear and easy for motorists to understand.

The service to check the MOT history of a vehicle will be also updated to reflect the changes.

5. Some vehicles over 40 years old won’t need an MOT

At the moment, only vehicles made before 1960 are exempt from requiring an MOT.

From 20th May 2018, most vehicles won’t need an MOT from the 40th anniversary of when they were registered.

The only exceptions to this new rule are vehicles which have been ‘substantially changed’ within the last 30 years.

A vehicle will be considered ‘substantially changed’ if the technical characteristics of the main components have changed in the previous 30 years, unless the changes fall into specific categories.

These main components for vehicles, other than motorcycles are:

Chassis - (replacements of the same pattern as the original are not considered a substantial change) or Monocoque bodyshell including any sub-frames (replacements of the same pattern as the original are not considered a substantial change)

Axles and running gear – alteration of the type and/or method of suspension or steering constitutes a substantial change

Engine – alternative cubic capacities of the same basic engine and alternative original equipment engines are not considered a substantial change. If the number of cylinders in an engine is different from the original, it is likely to be the case that the current engine is not alternative equipment.
