I was stopped for going 85 in a 65 zone. The ticket was marked posted-lidar- estimated. The trooper asked me if I knew how fast i was going and i said yes because the crusze control was on sixty five, my wife is the one that told me to set the control. The trooper said i came up on the car in front of me at 85 miles per hr. My wife watched him turn arround in his spot after returning from his last ticket stop or just arriving for duty at that location. This happen in MASS and I"M LIVE IN MAINE- Should I fight this? and what the hell ndoes estimated mean? thank you paul
