I got a ticket 4-years ago for not coming to a complete stop at a yield sign, the cop wouldn't let me say anything, he was very rude-total ass. Tried to show him in the driving book which i had in my glove box, that you do not have to come to a complete stop at a yield sign.
Instead of arguing further with the cop, i just took the ticket, went to court and had it dropped. The cop didn't show, but the district attorney said that doesn't matter, she had the notes from the cop during that day.
I went back to the scene and took a video of cars going though that same yield sign slowly, some drove though it full speed.
The video helped as i later found out this cop made a habit of giving out b.s. tickets which was originally $180 and 2-points.
That was the last time i ever got a ticket. Speeding is not that different, just mention to the DA you are willing to pay the fine if there are no points involved and even will take one of those traffic school classes. I took one just to reduce my insurance and it was funny as hell.. they went around the room asking everyone why you are here.
One lady said she was doing 75 in a 35 and didn't pull over for the cop for a few miles as she thought someone was trying to kill her. Another was driving with his headphone on and apparently didn't hear or see the sirens of a ambulance who was trying to pass him.
Good luck with your ticket.
