This is for a case in the state of California.
Hello,
I plan to take my ticket to court, using the defense of proving the lack of calibration of the device used to clock me (actually I'm fighting 2 tickets, 1 pacing, and one radar).
Firstly, has anyone had experience with this "ambush the prosecution on evidence" strategy? has it worked?
Secondly, and more specifically, I am under the impression that I can fight the ticket based on my exact speed. if the officer "let me off easy" by writing my speed down a bit, which speed do I have to fight them on? the one they wrote, or the speed I was going?
Secondly, I have a ticket that for speed says 90+ (while I know I was speeding, I am certain that I was not going this fast based on the car I was following. unfortunately that won't help in court). So how would I go about contesting that?
Thanks again for your help, this is a wonderful resource and I truly appreciate your time!
