Btw also get Waze app on mobile. I started using it couple of days back and its amazing. Waze has been bought by Google and basically looks like Google Map but you can see Waze users on map and users can mark police + speed traps for other users to know their locations. Also like construction and car stopped on the side can be marked by any user. Very nice app.

For your ticket you might need to do a little bit of homework. Search online and you will find details. This include requesting proof against you prior to court date. There are things the police officer has to do before he can use the radar gun.(write everything you remember from that day and use whatever you can against them). Little homework will go a long way. Also I heard if you change the court date to something other than what is given then there are more chances of cop not showing on the date as they have specific day set for just court hearings. For this you have to notify the court a week before and someone else has to go in and hand the letter over to the court if am not wrong. Letter should state that you are going out of town for work or something else.
