The way MOT testing works changed on 20 May 2018.
Use this guidance if you’re an MOT tester or involved in running MOT centres. It explains:
what the main changes to the MOT test were from 20 May 2018
Updated the 'Diesel vehicle emission limits' guidance to clarify the value that should be tested, and updated 'Lamps, reflectors and electrical equipment' to clarify what needs testing for reversing lamps. Removed the 'Other important information for MOT testers' guidance as this information is now in the MOT inspection manuals.
Updated the guidance about diesel vehicle emission limits to clarify the default limit for newer vehicles.
Updated the guidance documents to make it clear that the changes to the MOT have been introduced.
Added a new document covering other important information for MOT testers.
Removed ‘master cylinder cap missing’ as one of the defects that will no longer cause an MOT test fail, and replaced the MOT changes presentation for training sessions.
Updated the document about MOT inspection manual changes, as the manuals are now available in webpage format rather than PDF files.
Added a link to the MOT testing service training environment in the 'Identifying and recording the new defects on the MOT testing service' guidance.
