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.
