Question 1

Do MOT advisories mean my car is unsafe?

Accepted Answer

No. An advisory records an item that was still within the legal minimum on the day of the test. It's a note that it won't stay that way, not a judgement that the car is dangerous now. Anything genuinely unsafe is recorded as a Dangerous or Major defect and fails the test outright.

Question 2

Do advisories affect your MOT pass?

Accepted Answer

Advisories do not affect the result you've just been given. A car with advisories has passed, and the certificate is worth exactly the same as a clean one. The effect shows up next year: 31.2% of advisory passes fail their next test against 20.0% of clean passes.

Question 3

How long can I drive with an advisory?

Accepted Answer

For as long as the MOT certificate runs. There's no deadline attached to an advisory and no penalty for ignoring one, provided the item itself stays legal. The tyre is the exception, because tread depth can cross the legal line between tests.

Question 4

Will an advisory show up on a future MOT?

Accepted Answer

Yes, and it stays on the public record permanently. Testers often re-examine flagged items at the next test, so an unaddressed advisory tends to reappear rather than quietly vanish.

Question 5

Is it worth clearing advisories before selling?

Accepted Answer

Usually worth it. Any buyer can pull the full history in seconds, so unaddressed advisories highlight exactly where to push on price.
