.08 BAC

If you drive after drinking, and think that you can "function fine" while intoxicated, you are a stupid cunt, and I hope you get a DUI, and the state pushes your **** way in, and it is the life changing event that makes you pull your head out of your ***.
Because the alternative life changing event is killing or maiming yourself and/or other innocent people.
Absolutely zero tolerance for it, especially with all the options we have now. You don't want to take a cab or uber, riding with someone and coming back later for your car or truck is too much of a hassle?
Then regardless of how old you are, or how long you have been drinking, you are not smart enough or mature enough to drink in public in the first place. Stay your dumbass at home.
