laws vary from state to state in the US.
knock on wood; never got a DUI. Wont drive after drinking at all, it's sad but I can name at LEAST 20 friends who got DUI's.
while in arizona, if you get a DUI, you go to jail immediately, your stay at 'tent city' is determined by your blood alcohol content #.
Lucky for me, I now live in a city where you take a cab everywhere. The only time I drive, is when I go to my office, warehouses, or when I'm leaving town.
