I was traveling north on I-91 when I caught up to a VT State Trooper, not a peep from the V1. As we approach the medium cutover he flips on his K-band radar. This guy was hoping that someone on the other side would be speeding so he could flip around on the cutover and make the stop... which happened. Lights came on and everyone behind him has to slow drastically so he could make the turn then cut in to southbound traffic. I had the dash came running but forgot to lock the recording. Needless to say, I slowed a bit as I approached these spots from that point on.
