O Gentlemen I believe he refers to the mandatory inspection
https://en.wikipedia.org/wiki/MOT_test
All kind of horror stories of the inspector dropping your mint bike. Ramming the Chassis with a pointed hammer looking for rust and so on The car can fail the test and get large sums of repair costs.
Emission tests I hear about Diesel Filters and Exhaust Catalyst
Historically rust destroyed the day.
There is 3 grades of complaints remarks
1 Some defect that you need to fix
2. A defect you need to fix and come back within a month get approval
3.. Prohibition Cannot even drive the Vehicle from the place Need to tow it
Scrap it or repair come back
The slang is " The Spanish Flag " To be fair it is traffic dangers No brakes and so.
Rather than harassment .Which I have heard of.

I once failed a Exhaust sound test and there was 4 - 5 inspectors on the yard None of them seeing it may way '
And refusing consider any paperwork I could get.
I had to go to another town to get Approval.
