I was going down the freeway with my cruise control set at 60 and applied the breaks when I saw a construction sign. I passed an officer who waited a few seconds to pull out and then followed me for a while before pulling me over. The construction was such that 3 lanes merged into one and by the time he pulled me over traffic was completely stopped. He ticketed me for going 75 in a 45 construction zone and gave me $679 fine. I know I wasn't going that fast (I don't know how fast I was going) due to I was set on cruise at 60 and applied the brakes. I think due to the dark he caught someone else on radar and due to his delay in pursuit he pulled me over instead. What would be my best bet in court. How would be best to get my statement heard and hope for best results?
