Thanks for the advice. I just want to give everyone an update. So I went to court and show the prosecutor this video and he just quietly said that he is going to withdraw his case and I am free to go. I must said that the dash cam just save me $110. No way I would win this case without evidence.

I got ticked for disobey u-turn sign, but I drove into the parking lot before making the u-turn and then stop at the 'stop' sign before continuing. Does that still consider an illegal u-turn?
