In Illinois, the terms DUI (Driving Under the Influence) and DWI (Driving While Intoxicated) are often used interchangeably, but under state law, DUI is the official legal term. A DUI in Illinois covers driving or being in physical control of a vehicle while impaired by alcohol, drugs, or any intoxicating substance, including prescription medication.
Some states distinguish between DUI and DWI based on blood alcohol content (BAC) or the type of substance involved, but Illinois does not make this distinction—all impaired driving offenses fall under DUI laws. Whether your charge was labeled DUI or DWI, the consequences are the same, and both can impact your driving privileges, employment, and criminal record.
