Florida has a similiar statue for DUI. The law states that at .08 or if you appear to be impaired, you can be arrested for driving under the influence. Since the 2nd part is a judgement call by the officer, a lot of resources have poured into video cameras and mobile wolf packs that specialize in seeking out impaired drivers. Bottom line for me: if I'm driving I'm not drinking. If both the wife and I want to have a few for a night out on the town, than we take a cab.
