Whether or not you have previously been convicted of DUI, you can be charged with a more serious offense known as extreme DUI if your BAC far exceeds the legal limit at the time of your arrest. For example, if your BAC is 0.15 or above, you face a 30-day jail sentence in addition to fines and fees of at least $2,500. If your BAC is 0.20 or above, the jail sentence is increased to 45 days and the minimum base fine is doubled. Keep in mind that the jail time can be suspended with the installation of an ignition interlock device: all but 9 days in the case of an extreme DUI, and all but 14 days in the case of a super extreme DUI for a BAC above 0.20. Also, many jails offer home detention and work release to reduce the amount of time that those convicted of DUI spend in jail.
