I’ve seen a Mass. State Trooper sitting in the median on I-395 over a half dozen times over the past year. Heading northward from Connecticut into Massachusetts, you’ll see the car right before the state line behind a rock cutout. Although the car might be hidden good enough behind the rocks. (The cop would be sitting on the Connecticut side.)

I’ve not been pulled over here, but I slow down below 70 mph near the state line so I don’t get burned. I have seen cars get pulled over before Exit 1 in Mass.
