I shouted and screamed and took it the same day to another MOT test which it passed completely.
I then asked the MOT people to send an independent inspector.
Which it failed on the slight cuts in the tread (exposed cord, he said, easy to miss) but 'It has an MOT already so its leagl to drive'.
At NO TIME did it NOT have a legal MOT.
Therr is a world of difference between 'issues likely to become denagerous befire teh next MOT and 'issues that are so dangerous its not safe to drive teh car home'
In paricivulasr te MOT inspectoitr was scathing over the first garahge fior failing the car on issues like a proken exhaust support (£800 for as ne exhaust: fixed by 5 minutes of welding) which he said were faults, but not MOT failure points,
If it's at a test station you drive until you get a new MOT or the MOT expires. At which point you are allowed to drive it to a garage for the purposes of an MOT.
