As I've argued repeatedly in the past, drunk driving roadblocks (MADD and the police prefer the less ominous phrase "sobriety checkpoints") are overly intrusive and ineffective compared to police patrols. See, for example, Do DUI Roadblocks Work? and Do DUI Roadblocks Work? (Part II). And — despite a controversial 5-4 Supreme Court decision — they are unconstitutional. See Are Roadblocks Constitutional?
Their only real benefit is raising large amounts of cash for local municipalities from all the tickets and towed cars from unrelated license, registration and equipment violations (for which roadblocks would be illegal). See, for example, DUI Roadblocks for Fun and Profit and The New "Highway Robbery": Money-Making DUI Roadblocks Growing.
Recently, however, there appears to be the beginnings of a backlash from a few legislators unafraid of MADD's political influence.
R.I. Lawmaker: Outlaw DUI Checkpoints
