Bonzo,dont beat yourself up about the comments you made,there is so much myth about things relating to MOT Matters (no pun intended fellow NT's)and not one VOSA chappie will commit to saying Yes that is correct,the usual answer is "what does it say in the manual" answer,a lot of old cods.
The RTA makes no sense,the MOT is not worth the paper its printed on and only valid at the time of test and as stated on the rear of the form,its not a statement of roadworthyness and most would be horrified at what would pass the test going by the book and not what they think the book says and the way it is interpreted.
Everybody is entiteled to their opinoin and it sounds like we both suffer from excess time in the trade.
