I got pulled over in Arizona out of town on a highway for going 97. Luckily I had seen him and was able to brake down from 120 before he radared me. Even so, the speedlimit was only marked as 65. Being pulled over for speeding outside of city limits is much different then being pulled over inside of city limits. Being polite and respectful to the police officer was probably the best possible move I could have done, he wrote down my ticket as 84+. However that is still 20mph over the legal limit and it can become a felony if the court sees fit.
So my ticket came out to $207, but it really cost alot more. They made me attend 2 different traffic classes, each one over $100. And my insurance went up.
When I went to my court date is was nothing like I thought it would be. I very much doubt you will end up in a court room infront of a judge. When I got to the county judicial building the person working the front desk got my paperwork done and asked me how I plead (here is a hint for you guys, if you did it, admit it). So I plead guilty ofcourse, she told me the judge would meet with me in a few minutes. About 15 minutes later the judge came over asked me a few questions then said I would be eligible for traffic school since it was my first ticket.
I got off lucky compared to some stories I have heard about people speeding and such. If you handle it carefully and give respect to the people in charge, you will probably get off lightly.
