I have put together a brief description of some of the new  MOT regulations, as you can see the vehicle diagnostic indicators play a bigger part in the test now.


Advisory from January Fail from April

There is not much different here apart from (ESC) “traction control” and brake fluid warning light.
Condition including inappropriate repairs or modifications, operation and performance (efficiency test). Note the removal of the road wheels and trims are not part of the test. ABS or electronic stability control (ESC) where fitted. Check of the MIL for ABS, electronic stability control, electronic park brake and brake fluid warning.

Body or vehicle structure and general items

The test now includes the operation of the electrical socket for cars fitted with a towbar, the illumination of the speedometer  and worn or defective engine mounts.
Free from excessive corrosion or damage in specific areas. No sharp edges likely to cause injury. Towbar for security, condition, inappropriate repairs or modification. Correct operation of 13  pin electrical socket. Speedometer condition and operation. Engine mountings.

Electrical Wiring

The condition of a cars wiring will be inspected for damage this will be a visual check for chaffing, the MOT tester will not remove any parts for access.

Exhaust Emissions

If your vehicle has a decat pipe you will have problems as testers will now be looking for vehicles that have had their cat removed and they will fail the test.
Vehicle meets the requirements for exhaust emissions, dependent on the age and fuel type of the vehicle.


If your vehicle has (HID) High Intensity Discharge lights which are non standard the car will be likely to fail.
Condition, operation including HID and LED headlamps for cleaning, self levelling and security. Headlamp aim. Main beam warning light

Seat belts

Advisory from January Fail from April

Until now the airbag light was not part of the MOT, as of this month it will be included in the test this point will cause a lot of cars failing the test.
All the seat belts fitted are checked for type, condition, operation and security. All mandatory seat belts must be in place. Check of the malfunction indicator lamp (MIL) for air bags and seat belt pre tensioners.


In this part of the MOT the tester has to be able to adjust and lock the seat in at least three positions back and

forward it also includes electric seats.
Driver’s seat can be adjusted. All seats for security and seat backs can be secured in the upright position

Steering and suspension

Advisory from January Fail from April

Tyre Pressure Monitoring System is tested for cars 1st used from 1st January 2012.

Power steering fluid will now be checked, also the steering lock will be tested for correct operation. The tester will check for the presence of faults displayed in the vehicles system, these will include the tyre pressure monitoring system.
Condition, steering oil level, operation, a check for inappropriate repairs or modification including corrosion to power steering pipes or hoses. Operation of steering lock mechanism. Check of the MIL for electronic power steering and steering lock.

These are just some of the new regulations which will affect drivers there are also regulations that will have a greater impact on modified vehicles such as ride height and clearences between wheels and arches etc.
