When you send in your ticket, ask for discovery. Sometimes they screw up the ticket or have other fatal flaws. I got a real stupid one a while back and got in quite a discussion with the officer. He got kind of mad and took off at high speed. Sure enough, when I got the ticket, he had no notes. No notes = no evidence for the judge. Dismissed. Another time I got nailed in a real bad speed trap, ( school zone when the sign and school were not visible). The radar gun was not calibrated according to the recommended schedule. All the information was right there in the ticket. When I pointed it out in court, magically my ticket and about 90% of all the tickets for the next hour were dismissed. About $10,000 or more in revenue walked out the door as they were all school zone infractions in the same area. It was so fun I was tempted to camp out there and see how much money I could cost them.

Anyway, a simple note included with the ticket should suffice, but it is possible you will have to stop by the court and hand deliver a note asking for it. It takes a few minutes but at least half the time it presents an instant out for me. I haven't got one on almost 5 years, but when you drive 20K to 30K miles in the city, it seems to be just a matter of time before they find some way to catch you doing something wrong.
