What Happens After an Aggravated DUI Arrest in Chicago?
After you have been arrested for an aggravated DUI in Chicago, you should know that you will face the following:
- Felony Charges: You can face a Class 4, 3 or 2 felony charge, depending on the circumstances surrounding your aggravated DUI case.
- A Bond Hearing: You will appear before a judge for a bond hearing, shortly after your arrest, to determine bail conditions.
- Statutory Summary Suspension: Your driving privileges will be automatically suspended 46 days after your arrest, but you can contest this in court.
- Vehicle Seizure: Your vehicle may be towed and impounded, and potentially subjected to forfeiture. This is especially likely if your case involves driving on a suspended or revoked license, prior DUI convictions or an accident causing injury.
How Aggravated DUI Differs from a Standard DUI in Chicago
An aggravated DUI is different from a standard DUI, in both its classification and severity.
When you are charged with an aggravated DUI in Chicago, you may face the following:
- Felony Charges: While a standard DUI is a misdemeanor offense, an aggravated DUI is a felony offense– usually a Class 4 or 2, with higher classifications possible, in the most severe cases.
- Prison Exposure: While a standard DUI results in county jail time, an aggravated DUI can result in a state prison sentence, which carries stricter conditions, and significantly fewer privileges.
- Longer License Revocation: Your license is likely to face a longer license revocation, and along with that, more restrictive reinstatement requirements and, in some cases, the mandatory use of a Breath Alcohol Ignition Interlock Device (BAIID).
- Long-Term Effects on Your Life (restricted employment and housing, loss of professional license): These long-term consequences often extend well beyond the courtroom and can shape your opportunities for years to come.
- Collateral Consequences (vehicle seizure, extended supervision or probation): You could also face additional consequences such as vehicle seizure, extended supervision, or lengthy probation terms.
Because an aggravated DUI is among the most severe DUI charges you can face in Illinois, the consequences are significantly more severe than a standard DUI. To protect your rights and explore your defense options, you should speak with a Chicago DUI defense lawyer as soon as possible.
Penalties for Aggravated DUI in Chicago, Illinois

Given the severity of the penalties associated with an aggravated DUI, early legal representation is critical to understanding your exposure and protecting your future.
What the Prosecution Must Prove in a Chicago Aggravated DUI
The prosecutor will have to prove, beyond a reasonable doubt, that you were driving under the influence of drugs or alcohol (0.08% BAC or higher) and an aggravating factor was present.
These factors include:
- Great Bodily Harm
- Death
- A Third or Subsequent DUI
- Driving with a Child Under 16
- Driving Without a Valid License
Prosecutors will rely upon police officer observations, body camera footage, field sobriety tests, chemical test results, accident reports and witness statements.
In a death or injury case, the prosecution will have to show that the intoxicated driving was the proximate cause of the accident (meaning your impaired driving is what led to the crash or injury). In these cases, they may rely upon accident reconstruction, medical records and expert testimony.
Because the evidence in question is not always conclusive, each piece should be thoroughly examined for accuracy, reliability and compliance with proper procedures.
