Any vehicle that is three years or older required a valid MOT certificate.
Pass = a VT20 is printed off for your records and the information is instantly logged into the PNC so you can order road fund license by post or take your VT20 to the post office.
Advisory = your vehicle has some issues that have been noted by the tester as he conducted the MOT test. They may require work or are to just apprise you of the condition of your vehicle
Fail = your vehicle has some issues noted by the tester as he conducted the MOT test which fail to meet the MOT criteria.
This is only a test of the vehicle as presented and does not guarantee that the vehicle is completely road worthy or fault free.
