chances of getting a disobeying sign ticket dropped in court.

I was running late because I had to stay after work because someone showed up late. So i was on a hurry on my way to church. I was making a left hand turn on a empty intersection when i see a cop car about a block down parked. I admit i rolled the sign and got a ticket. From the location at where he was sitting he had no way of telling if i stopped prior to the white line since only the white line was visible. He pulled me asked for licenses and registration and gave me an immediate ticket. This is the cops first year on the job. Any chances i can plead not guilty say i stopped early and either get the ticket dropped or lowered? I have a clean record. I have already taken pictures and done research with a friends car.
