# What is the typical duration of Illinois DUI court supervision?

Illinois DUI court supervision typically runs 12 to 24 months, with the ceiling set by 730 ILCS 5/5-6-3.1 at two years. Cook County and the collar counties often impose 12 to 18 months for a straightforward first-offense case. Aggravating facts such as an accident, elevated BAC, or child endangerment push the term toward the maximum. Early termination is available in some counties once conditions are satisfied. A Chicago DUI lawyer negotiates duration alongside the conditions, since a shorter term with completed classes and community service is often preferable to a longer term with lighter requirements that generates more chances for a violation.
