I encountered the sobriety checkpoint at the southern end of 140 in New Bedford once. I recall it went like: “Have you been drinking?” “No” “Your eyes look bloodshot.” “It’s 11:00. I’m tired and going home to bed. Am I free to leave?”

That was the end of it. I don’t like the fact that roadblocks exist but the courts have ruled them legal as long as they stop everyone. It would be a good ballot initiative to amend the state constitution.
