No, the MOT doesn't claim to cover every part of the Construction and Use or Road Vehicles Lighting Regs. It checks your car is safe, not legal. It's the driver's responsibility to keep the car legal, the MOT makes sure it's safe enough to be around other people. The speedo is now covered though, but has only been so for about the last 2 months. It just has to work the accuracy isn't tested.
The mot is just a test to make sure the vehicle meets the very minimum legal requirements, not really to make sure its safe, obviously the vast majority of safety critical stuff is covered in the mot, ive been left with no choice for a few dangerous thing, but to advise them, because thats the only options the computers allowed me to do. If you look at an mot certificate it says on it something like, this test does not confirm the vehicle is roadworthy, just that it meets the legal requirements at time of test. Ill never understand why people rave about buying a car just because its got an mots on, coming from a tester, mots aren't worth the paper theyre written on.
A section from the mot manual regarding method of inspection, and reasons for rejection regarding speedos.
