it will come into effect when we get the special notice but as of now they will only be advisories. so i had a check today while doing me mot's & 2 would have failed for not displaying the BSAU 145d marking & not displaying the name & postcode of the supplying outlet these are required for vehicles registered on or after 1 September 2001 & 1 would have failed for displaying the union jack flag at the side of the number plate.
also which is a bit worrying some stations have admitted to charging more then the legally allowed maximum fees. so check what they have charged you before you part with your hard earned cash.
