The law of the land is that driving with a blood-alcohol level of at least 0.08 percent is a crime, though exactly how the crime is punished varies from state to state. (The Governors Highway Safety Association has a handy list here, outlining how the punishments vary in terms of length and what happens to the drivers.)
Arizona added the “super extreme DUI” charge in 2007 to cover anyone with a blood-alcohol level of at least .20 percent, which can carry with it a sentence of 45 days in prison. The “extreme DUI” category in Arizona, covering measurements of at least 0.15 but less than 0.20 percent, has a punishment of 30 days in prison.
