I guess I have some not so unique experience. I was given a DUI in 2011 during a routine traffic stop. They officer cited I cut the protected left turn too tightly. The officer then said he smelled marijuana, even though I was currently smoking a normal cigarette. I was arrested immediately, my blood was taken, and being an occasional pot smoker, THC was in my blood, I got a DUI while completely sober driving to work at 9 AM.
Seems like a lot of folks in this thread would call situations like yours "necessary collatoral damage." Some of the stuff I'm reading here is genuinely disgusting, and it makes me uneasy to think I might work with some of the folks espousing it.
I don't see how this is necessary collateral damage for the prevention of drunk driving. I think most folks in this thread would agree that current implementations leave an awful lot to be desired, regardless of what they believe the best approach to be theoretically.
That's a problem with specifics though, not with the general existence of DUI laws. Weed will be hard to enforce but BAC is more cut and dry, I don't see a problem with having a BAC cutoff for driving.
I've seen a handful in CA. Usually they're visible from a large distance, given the flashing lights and traffic backup. Sometimes they'll even have signs up a few blocks in advance warning about the upcoming stop.
I used to commute in a red sports car at midnight, and my direct path to the freeway and home was regularly blocked by a checkpoint. The officer started to instruct me on being checked, and I whined that I was tired, and he waved me by. Town was notorious for interfering with traffic with their checkpoints and speed enforcement. Sometimes checkpoints were disclosed on radio. Looking back it’s amazing they didn’t cite me for my confessed exhaustion. Also this was a long time ago so YMMV.
