Changes to MOT tests to be made in England, Scotland & Wales on 20th May | Snows Blog

What to expect when you next have your MOT carried out

Keep up to date with the latest updates and guidelines on MOT testing introduced as part of EU Directive 2014/45 on 20th May 2018.



Why are these changes being made?

Changes to MOT testing are being introduced as part of the EU Directive 2014/45, which will be put into action on Sunday 20th May 2018 in England, Scotland and Wales.

These changes stem from the political action back in June, when the UK voted to leave the EU in the 2016 EU Referendum. The UK will still be an EU member on the 20th May when the directive comes into force, meaning that the UK government must make sure that these changes are introduced to avoid any ongoing substantial fines.

So what's changed?

Currently, for vehicles to be driven on Great Britain's roads there are 2 main legal safety requirements - it must be roadworthy and have a valid MOT. This is something that will not be changing on 20th May 2018.

When you have your MOT carried out on your vehicle, any defects found by the technician will be recorded and categorised as either: dangerous, major or minor, which will all depend on how serious the defect is.

From 20th May, the implementation of the new directive will pre-define what is considered as ‘dangerous’. Defects that are failure items but aren’t deemed as ‘dangerous’ will be called ‘major’ defects. In line with this, DVSA have made the wording on the MOT failure documents clear in reminding motorists that driving a dangerous vehicle is illegal.

The other new category to be implemented is 'minor'. This is where there’s a defect on the vehicle – but it isn’t serious enough for the vehicle to fail. Like the major and dangerous defects, they are also pre-defined for you. And, like the current MOT test, we'll still have advisories.
