What it fails on, and why
Tyres fail for tread below the 1.6mm legal limit across the central three-quarters, uneven or exposed-cord wear, or sidewall damage. The tester inspects all four; a single illegal tyre is a fail.
This covers a range of smaller items, from a non-working horn to a warning light left on.
Fuel-system failures are leaks or an insecure filler cap.
