New MOT regulations come into force in the first major overhaul in 5 years
The changes to the rules mean it will be harder than before for vehicles to pass their MOT test
The vehicles are to be put through tougher emissions tests and faults rated in three defect categories.
New 'Minor', 'Major' and 'Dangerous' categories will be applied to all cars in order to meet European Roadworthy status with Major and Dangerous resulting in automatic fails.
Cars with minor defects will be allowed to pass and the faults will be recorded but those that fall into the dangerous category will be subject to and automatic fail. Dashboard monitoring is also set to get stricter as any lit warning light will result in failure of the test.
In the past as long as your car was deemed roadworthy, you could keep driving it, even after it has failed provided your old MOT was still valid.
They are also clamping down on DPF tampering and removals, if it has been removed or tampered with in any way it will not pass - unless it can be proved it has been done so for filter cleaning.
