If breath/blood tests provide results showing blood alcohol content at 0.08% or higher, you’re presumed to be driving while impaired. For first-time convictions, DUI is a Class 1 misdemeanor which imposes a mandatory minimum fine of $250, driver’s license suspension for one year, and possible incarceration up to 12 months. Higher concentrations of alcohol in your system result in the imposition of minimum mandatory jail sentences. Subsequent convictions result in increased fines, increased suspension of license, and increased jail confinement. Those found guilty will also be referred to court-approved counseling programs, the cost for which is also the responsibility of the defendant. If you are permitted to have a restricted license, an ignition-interlock system must be installed in your vehicle (this involves a substantial fee) and it applies to those under age 21 as well.
