What Is an Aggravated (Felony) DUI in Illinois?

When a DUI Becomes a Felony

While most DUI charges start as Class A misdemeanors, Illinois law elevates certain cases to felony status based on aggravating factors. Any DUI charged as a felony is legally classified as an Aggravated DUI.

Why Felony DUI Charges Demand Immediate Legal Help

Mandatory prison sentences

  • Long-term or permanent driver’s license revocation

  • Thousands of dollars in fines

  • Permanent felony criminal record

Once felony charges are filed, early intervention can significantly affect the outcome.

Common Situations That Lead to Felony DUI Charges

Examples of Aggravated DUI in Illinois

A DUI may be charged as a felony if it involves:

  • A third or subsequent DUI conviction

  • DUI causing great bodily harm, permanent disability, or disfigurement

  • DUI resulting in death

  • DUI while transporting a child under age 16

  • DUI committed while your driver’s license is suspended or revoked

  • DUI without a valid driver’s license or permit

  • DUI without mandatory vehicle insurance

  • DUI committed while revoked for prior DUI, reckless homicide, or hit-and-run

Each scenario carries unique legal risks and requires a tailored defense approach.
