On RTE 25/ RTE 8 connector, CT state cops can been anytime of the day, pulling people over for speeding. The speed limit is 55mph but most people go much faster. The State Troopers also use multiple cars at multiple points (I was 7 cars once at 4 separate point) to ensure coverage. The troopers will also sit below grade so you don’t see them until its too late or sit around a bend and then grab you as you come by.
