The incident took place at midnight on a Wednesday night. There is not much of a shoulder on 270 North between Germantown and Frederick, so this officer was parked right before the Rosemont Avenue exit. He was using radar, KA band, and probably that ‘instant on’ technique. My detector did not pick it up until it was too late. I was going with the pace of traffic, and there were two other vehicles going the same speed, but I was the one that got pulled over. The ticket was for going 74 in a 55 zone, a $80 offense. It may also be worthwhile to note that a friend driving up the same night saw the police vehicle parked on the other side of the highway an hour later on 270 South.
