Her "roadside plea bargain" was to charge him with "Obscured License Plate". It was dirty from driving the backroads on a winter day (gravel roads were wet).
I have encouraged him to fight this ticket but his controlling mother just wants him to pay it
I think you can still fight this. If you have a good driving record, just take a copy of your driving abstract from an mto, and simply ask for a reduction from the "Obscured License Plate".
He has to give you another reduction. You can usually get two reductions. First from the police officer and another from the courts.
I'm not sure what you mean by, "He HAS to give you another reduction". I know of no legal duty for either the cop OR the Crown to reduce ANYTHING. Accepting a plea-bargain should only be considered if an accused is scared to death of the trial procedure, or the stakes are too high (serious offense).
Sometimes if they see the officer has already lowered the ticket on scene, then the prosecutor might say no, but in some instances the lowered ticket by the officer may not be of any great value, so then the prosecutor might lower it again to the suitable charge and fine.
This is always different for each person, but if you can manage to convince them your ticket is unique, and your driving record is good, then they will be more inclined to help.
If you already have speeding tickets etc., then most likely they wont help you out.
So yea theres no obligation, but its more of a courtesy, and a mercy by the courts.
Thanks for asking and clearing that up
