Back in my drunk driving days, I would have never been caught in a checkpoint because I avoided main roads.
Yup; those were the days! NOT! (How did I manage to live through them?)
Around here, Alabama, most check points are on side roads. Had one on main state highway going thru next town by local cops, and stopped several hundred after work drinkers.over 150 were detained,also ONE lawyer. Law here requires state
approval and state patrol present on state highways All charges dropped.
Took lawyer several days to find and report law, made newspaper.
