Advisories are used for two reasons:
- to tell the presenter that a component is close to becoming defective
- to make a note for both DVSA and the presenter that the item was not able to be assessed during the test
The second scenario can happen when its vehicle standards assessors (VSAs) are unable to gain access to read the four-digit date code on the tyres, as part of a twin wheel set up on a heavy vehicle.
DVSA has published a note to reassure operators that this advisory does not reflect poorly on them, does not affect the roadworthiness status of the vehicle and does not affect its Operator Compliance Risk Score (OCRS)
DVSA said: “The advisory is a reminder to the presenter or operator that they need to be confident in their tyre management system. Your tyre management system should mean that you know the age and legality of all your tyres and take appropriate action where needed.”
It adds that these advisories are different to a situation where a date code is missing or damaged. If found on a steered front axle during the annual test, that will be marked as a failure.
