As far as the radar goes...I don't think they are required to show it to you but they are required to test its calibration if you ask them to. I was pulled over today (52 in a 35) and he asked me about the test, I declined....just wanted to get on my way. Anyways, he ended up giving me a warning but a few years ago when a cop pulled me over for speeding, he was a jerk the entire time. Anyways, I asked him to do the test and he said it tested accurate, when I asked to see it he said he isn't required to show me,( hense I know he was full of shit about me speeding to begin with).
As far as the ticket, just go to court and plea no contest or guilty with explanation and ask for a reduction based on your record. Generally, if you go in there and act like you weren't raised in a barn and start acting like you run the show, they will cut you some sort of break.
Good luck!!!!
