ITS A TRAP!!!! lol
Protip: make a mental note of where the DUI checkpoint is, and what time it is, because they WILL re-use it again in that county. The window is usually like 10pm-2am or some
shit, or at least thats the time I've seen most of them.
FTR I drive sober (like to the point where I dropped like $300 going to hotel + uber in boston one night last summer because I didnt want to take even a remote chance) but I dont submit myself to that bullshit if I dont have to. Most of the time the delays by itself are annoying enough as it is. One night on rt2 they blocked the whole f***ing highway off. I really wanted to say "So, where do I get my gas card? You know, for the like 6 bucks in gas I burned up just sitting out there waiting to get through here... the gas I wouldnt have burned if this clown show wasnt here" but I thought better of it, because I bet half the guys at those things dont really like it either.
So you smile and nod and be on your way, lest you add even more delays....
