What Does the State Need To Prove in an Illinois DUI Case?
Under 625 ILCS 5/11-501, it is illegal to drive or be in actual physical control of a vehicle while under the influence of alcohol, drugs, or a combination of both. To secure a DUI conviction, the prosecution has to show two things: that you were in control of the vehicle and that you were impaired at the time.
