Another informative po for the Tsikoteers!
4. MMDA has confirmed that your license MAY NOT BE CONFISCATED at a traffic apprehension. The only time they can do so is if you are part of an accident, or it is your third violation and you have not settled your fines yet. They are only allowed to give you a ticket, which you can contest. He recommends actually receiving the ticket in some instances, so that you can report the officer who did it.
Also, you are free to ask any of these officers for their "mission order", which is written by their supervisor. If they apprehend you for a violation that is not in their mission order for the day, you can report them and they will receive disciplinary action.
So go out and enjoy!
