From THIS SUNDAY, changes to the regulations – the first in five years – will see new ‘minor’, ‘major’ and ‘dangerous’ categories being applied that could affect thousands of motorists in England, Scotland and Wales.

These defect categories will be applied to all cars in order to meet the European Union Roadworthiness Package, with major and dangerous issues resulting in automatic failure.

When does the new MOT test come into effect?

The MOT test will change on May 20, stricter rules for diesel car emissions with a diesel particulate filter (DPF), which captures and stores exhaust soot to reduce emissions from diesel cars.

There will also be new tests in the updated MOT including under-inflated tyres, contaminated brake fluid, brake pads missing or defective warning lights, dashboard monitoring and fluid leaks posing an environmental risk.

A car will fail if smoke of any colour can be seen coming from the exhaust or there is evidence that the DPF has been tampered with.

The new rules will also mean that some vehicles over 40 years old will become exempt.

For example, if a car was first registered on 31 May 1978, it won’t need an MOT from 31 May 2018.

Over the years, as long as a car was deemed roadworthy, motorist could keep driving it even if it failed as long as the old MOT was still valid.

What the new categories mean:


A direct and immediate risk to road safety or has a serious impact on the environment. Do not drive the vehicle until it’s been repaired.

Result: Immediate fail


It may affect the vehicle’s safety, put other road users at risk or have an impact on the environment. Repair it immediately.

Result: Pass


It could become more serious in the future. Monitor and repair it if necessary.
