That's about it, you passed and apparently so did others in your batch. You'll see them get some drivers out and administer a 'field sobriety test', which includes walking a straight line, standing on one leg, touching their nose with their index finger and saying the 'abc's'. By then there usually isn't much doubt about it. The driver's arrested, car is towed, and breathalyer at the station before booking. They have sobriety check points periodically around here and generally near known drinking districts.
Oh, ok. It just seemed like an odd time of day to have a checkpoint, though I suspect it had something to do with the street fair. Very inconvenient for a good girl heading from church like me.
Of course, I did have a margarita with dinner, afterwards...
We used to have them all the time at Fort Gordon. They of course, also included some security nonsense, but it was really sobriety they were after. I was almost always on a weekend and always at night.
The real security checkpoints were 24 hour stops and everyone had to go through those... especially during heightened threatcon levels. Made us sometimes up to 45 minutes late for shift. Thing is, I would not have minded so much exept that if I were a terrorist, I would not need to bring in a truck. The base was not fenced!
