Ouch! Of course, "Adrian", or whatever your name is. Nothing like a bit of playground banter to help you win an argument, is there?
None. It isn't relevant to your statement. There are plenty of issues that would render a vehicle illegal to use, which are nothing whatsoever to do with roadworthiness, or the MOT. What is relevant is that at the time of the MOT, it meets "the minimum legal requirements for those items prescribed under the Act". "It does not mean........ that it will continue to be roadworthy for the next year", implies that it must be roadworthy at the time of the test.
Anyway, to get back to the point, perhaps you will provide a link to where Vosa explicitly deny that an MOT test is a test of vehicle roadworthiness..................... then I'll let you go back to the playground.
