Changes to MOT standards went into effect May 20, 2018. The changes mainly affect the windshield and side windows. Going forward all test standards will be judged and put in minor, major or dangerous categories.
If a car has major or dangerous defects it will not pass its MOT. A car can also fail if damage on the windshield is more than 40 mm in size. If a vehicle owner fails a MOT he or she must have the issue resolved and have another MOT test to ensure their vehicle passes. “Basically, it’s in the interest of the vehicle owner to have any damage repaired or the windscreen replaced before the MOT test as otherwise you will end up paying for two MOTs. It is also worth noting that the first failure will be recorded on the vehicle’s MOT history,” Alistair Carlton, technical manager at National Windscreens said.
MOT testers are also looking at vehicle emissions while following standards and procedures from the Driver and Vehicle Standards Agency (DVSA). “The new DVSA MOT procedures are targeting mainly the emissions from diesel vehicles but that does not detract from the existing checks on visibility that many motorists can often be unaware of,” Carlton said. Overall the test will still focus on driver visibility but now will have stricter categories.
