I'm seeking the same information. I intend to respond YES to question 23, as I have two traffic violations (speeding and following too closely) and one parking ticket. In the documentation section, I won't be attaching any files. as we "You do not need to submit documentation for traffic fines or incidents that did not involve an arrest or did not involve drugs or alcohol, if the only penalty was a fine of less than $500 or points on your driving record." and finally will bring tickets and payment receipts in the interview.
