Randolph PD officers usually parked on the side of the ride with their cruiser off running radar waiting for cars going downhill roughly 1600 feet past Canfield Ave going west on Route 10. They run this during the night on the downhill stretch going into Roxbury and appear as a car on the side of the road using the emergency shoulder lane, but by the time you realize it isn’t a car left on the side of the road and then quickly see Randolph PD is tailgating you it’s too late. 50mph speed limit and cars usually gain at least 5-10mph driving down the downhill portion and the speed limit is strictly enforced.
