You're kidding, right?? That violations schedule is chump change compared to my town. I got a double ticket 2wks ago: expired meter = $29 and Street cleaning = $42. I just ran in to someone's house and back out- under a minute; I don't know where these bastards came from.
Don't know if it's much different than anywhere else, but for parking violations, there is no jury, therefore no trial. The judge just hears your case, and makes his/her decision right there on the spot. Most judges will accept any type of electronic media for supporting evidence, even a pic on your camera phone. Bring anything that you think might help your case. Even if you were in fact parked too close to a driveway, the judge may still dismiss the ticket . . . most of them are aware of the parking problems in the city they preside in, and know how hard it is to find a spot in certain areas. They do take that into account when they hear your case. Just be straightforward about it. Good luck man!
