You have to attach a copy of your "certificate of good conduct" (your file at in the police database). It has to be the "extended version" even for the PPL licence application..
Regular traffic fines won't be a problem. However, if you loose your car licence for more than a certain period of time (6 or 12months, I think), you were also put to trial for it, and the CAA can postpone your licence for a certain period from the time of the "crime". Think this has to do with a probation period that your get on the car licence (two years?).
