DUI offenders or those that have been found guilty of driving under the influence will face very steep fines and probation, even for a first offense. Those that injury or kill someone or are repeat offenders will face felony charges and long jail sentences. In every area of the United States there is now the mandatory suspension or revocation of a driver's license if they are charged with a DUI, and this can be enhance depending on the situation of the arrest. Those with higher than double blood alcohol levels, typically 0.15 in most areas, will face the most significant penalties. Most areas now also have a mandatory ignition interlock device that also has to be installed, at the DUI offender's cost, into their vehicle. This device requires that the individual blow into it to do a breathalyzer before the vehicle will start, as well as at routine intervals while the vehicle is being operated. The offenders are not allowed to operate any other vehicle, regardless of the reason, for the duration of their probation.
