Okay, so I got my first speeding ticket a few weeks ago, and my court date is coming up in another month from now... supposedly I was going 80mph in a 45 zone, although I don't think I was going as fast as 80, and the zone is definately a 55. Regardless, the cop wrote on my ticket that I was going 80 in a 45 zone, but he wrote "No" in the box indicating whether or not he caught me on radar.
For any of y'all familiar with traffic violation court procedures, traffic school, fighting tickets etc. do you see any way I could possibly get out of this? I heard that if the cop doesn't show up to the court date you get dismissed. But say he does show up, will I have a chance of getting my fine reduced if I can prove that the speed limit was actually 55? Or are my chances better considering he didn't get me on radar?

Maybe I should be asking elsewhere but any help would be nice.....
