The fine for DUI is 3months loss of license and your car impounded for 28days 2nd time is 6months 3rd time is 12months. if your caught driving when your not meant to be its another 3months added on.
but everyone must of drunken and driven at some point i used to be a country boy and i remember waking up in say states e.g still in the car engine running fallen asleep in the driveway.
don't get me wrong i don't condone this kind of behavior i just happens i have a friends whose dad has been to prison for drink driving does it stop him, No.
Addiction is a powerful thing, and it'll normally take i big moment (scare) like this to break the habit.
