But presumably they could fail you, thereby forcing compliance by mandating you have the problem corrected somewhere?
They could... assuming they do the inspection
correctly. But therein is one of the problems:
"2/. Headlamp aim consistently tops the MOT compliance surveys as one of the most likely items to be
assessed incorrectly by testers"
So while lighting and signalling accounts for 19% of all MoT failures and is reckoned to be the top point of failure by the RAC, according to data they got from from the DVSA, it stands to reason that many headlight alignment failures could be down to the tester not properly applying the test... as well as many poorly aligned headlights getting passed as a result of the same mis-assessment.
However, forcing compliance is another matter, with 2023 reports suggesting that up to a quarter of drivers admit to having knowingly driven without a valid MoT... how many more did so but
didn't admit to is is anyone's guess, but the reports only sampled 2000 drivers. Either way, I imagine a fair few people wouldn't bother.
The DVSA inspectors will only visit a MOT station every 3 years if its (and it’s testers) status is green or every 12 months if it’s red, and they only inspect one car from one tester.
OMG, how lazy are they? It's only 24,000 test centres they have to inspect....!
I guess it doesn't matter how super-hot they are, if they're not applying it...
I can see this, with all the new technological online capabilities, ending up with testers having to include photo/video evidence of particular pass or fail points.
