on a side note, I have never deen a DUI checkpoint in the morning on my way to work. IIRC each one was after 10 pm. I also don't know of anyone who conducts job interviews, or doctor offices open that late.
I work 11am-11pm at a hospital.
I have been pulled over for no reason before. I also didn't get a ticket any of those times once they saw the scrubs and talked to me. They were obviously trolling for drunks.
Heck, I was given a warning once when I was speeding quite a bit trying to get in quick for a stroke.
I have never seen a DWI checkpoint though outside of Hawaii.
