I think Ronin has the right approach here.

I got a ticket about a year ago going 69 in a 45 mph construction zone. The cop was "nice enough" to mark the ticket at 59 in a 45 construction zone to reduce my double fine fee to $400 and some odd dollars. The trouble I had with the ticket was the construction zone wasn't marked on the side of the road I was traveling. The construction was 4 lanes and a median away, off the shoulder, on the opposite side of the highway. I would gladly slow down for safety, but I had no idea I entering a construction zone and there were no signs.

I went to court and told the ADA my side of the story. He said, you know you are about the 6th person to tell me a very similar story, all tickets from the same cop. How does defective windshield, no points, sound instead? I took the non-moving violation in a heartbeat.

Now if I felt like I really deserved the ticket I might take a different approach, but I think the courts will work with you to reduce fees and points either way.
