reversing lights

Oh the joys of the MOT system. You couldn't make it up!

So all rear lights apart from reversing lights would fail if they show any white light to the rear, wouldn't be so bad, but the reversing lights are still on when the bloody thing is going forwards, well you only have to turn ignition and they're on! Obviously a fault with switch or something,but can't fail as 2007! Yet 2009 would fail! What's the difference, same fault different year is pass or fail. These black and white areas are starting to look a bit grey around the edges.

dizzydiver ii tested a 64 plate Vauxhall corsa yesterday and the air bag. light Was on × 2   on the dash  however I could not fail it for that I did fail it on emissions. For a mil light and the CO test for a 2nd fast TEST 

Before the year 2005 ish I remember the hand written VT30's. ten years of my life taking cars for mot's and anything and everything the tester wanted to fail was on it. I even remember my dad telling me about an early Citroen that a tester failed for excessive corrosion to a door step/outer sill panel. My dad repaired it the same way the manufacturer made it, but upon retest the tester failed it because my dad had pop riveted the new panel section back in place. 

Who was correct the tester or my dad?

Citroen run their petrol fuel lines through the sill panel which is why the sill panel was rivetted and not welded. The tester won't agree to the panel being rivetted so failed it. My dad went to Citroen and got a letter from them advising that was the correct repair procedure and how they left the factory. My dad went back to the tester and he would not accept the terms of Citroen for their repair criteria, as presented on their letter headed paper. You know we all have differences of opinions, but the mot criteria was designed to follow the manual (even when poorly presented), and if something like this citreon is presented for test then a simple phone call to GOV for advice would suffice.  

Bad example for the black and white/grey area. That bit could not be easier to define or apply.
