how soon can I bring an MOT forward
car fails the MOT-the original pass is still valid. In fact you can have the Test done up to a calendar month before the expiry date and have the new MOT forward-dated to the expiry date of the existing certificate.o if you take your car for an MOT and get a pass, then take it again a week later and get a fail, you will still have a valid MOT certificate for the following 51 weeks of the year until your original certificate expires.
