whoops, my bad... honestly its going to be tough, its going to come your word vs theirs. what you would need to challenge is whether or not they had a clear and unobstructed view of your vehicle. just lay it out as you did on the forum referencing the possibility that the speed was from the other vehicle. the thing is if your speed was captured via laser then the laser had to specifically be pointed at your vehicle but if it was radar then there is a chance it go the speed of the other vehicle. other then that request the logs of the calibration for the device... good luck
