What is a DUI in Illinois?
In Illinois, a DUI (Driving Under the Influence) means operating a motor vehicle while your ability to drive is impaired by alcohol, drugs, or any intoxicating substance. You can also be charged with DUI if your blood alcohol concentration (BAC) is 0.08% or higher, even if you don’t feel impaired.
DUI laws in Illinois also apply to drug-related impairment, including illegal substances and prescription medications that make driving unsafe.
You can still be arrested for DUI in Illinois even if your BAC is under 0.08%. If your driving is affected by alcohol, drugs, or a combination of substances, you can still face DUI charges under Illinois law.
Illinois DUI laws are found under 625 ILCS 5/11-501, which sets out how DUI is defined, how it’s prosecuted, and the penalties involved.
Types of DUI Charges in St. Clair County, IL
DUI charges in Illinois can vary depending on the circumstances of your arrest, your driving history, and whether anyone was harmed. Here are the DUI charge types most commonly seen in St. Clair County, IL courts:
First-Time DUI (Class A Misdemeanor)
A first DUI offense in Illinois is usually charged as a Class A misdemeanor. Penalties can include up to one year in jail, fines as high as $2,500, a minimum one-year license revocation, and required alcohol education or treatment.
Aggravated DUI (Felony)
A DUI can become a felony if certain aggravating factors are present. Common aggravating circumstances include:
- Being arrested for DUI while transporting a child under the age of 16.
- Driving under the influence and causing a crash that leads to major injuries or fatalities.
- Facing charges after accumulating three or more previous DUI offenses.
- Being charged with DUI while driving with a suspended or revoked driver’s license.
Aggravated DUI charges carry much harsher penalties, including possible prison time and long-term loss of driving privileges.
Repeat DUI Offenses
A second or third DUI conviction can lead to much steeper penalties. Repeat DUI offenses often result in more jail time, lengthier license suspensions, and stricter court oversight.
DUI with a Minor Passenger
Driving under the influence with a minor passenger can lead to enhanced penalties, including mandatory community service, additional fines, and potential felony charges.
DUI Causing Injury or Death
A DUI accident that causes serious injury, permanent harm, or death can lead to aggravated DUI charges and significant prison time.
If a DUI accident results in serious bodily injury, permanent disability, or death, you could face aggravated DUI charges and lengthy prison sentences.
Drug DUI
In Illinois, you can face DUI charges for driving while impaired by illegal drugs, prescription medications, or even over-the-counter substances that affect your ability to drive safely.
CDL DUI
Commercial Driver’s License (CDL) holders face harsher DUI penalties in Illinois. A first CDL DUI can lead to a one-year CDL disqualification, even if you were driving your personal vehicle. A second DUI results in lifetime disqualification. CDL drivers are also held to a stricter BAC limit of 0.04% when operating commercial vehicles.
DUI Penalties in St. Clair County, IL

Summary Suspension and License Reinstatement After a DUI in St. Clair County, IL
Following a DUI arrest in Illinois, your license is automatically subject to a Statutory Summary Suspension before you are found guilty of anything. This suspension is triggered if you either fail or refuse a chemical test (such as a breath or blood test).
Statutory Summary Suspension
- Failed Test (BAC 0.08% or higher): Triggers a 6-month automatic suspension of your driving privileges.
- Refused Test: Leads to an automatic suspension of your license for 12 months.
- Commercial Drivers: Immediate CDL disqualification can apply even if driving a personal vehicle.
You can challenge the summary suspension by filing a Petition to Rescind. You must file this petition within 90 days of receiving the suspension notice or attending your first court date, whichever happens first.
The court must schedule a hearing within 30 days of filing the petition or within 30 days of the first court appearance, whichever is later. If the hearing does not occur within this time frame, the suspension may be automatically rescinded.
License Reinstatement
If your driver’s license is suspended because of a DUI arrest, a DUI lawyer can support you through the following actions:
- Prepare and submit the necessary documents to fight the suspension.
- Appear on your behalf at hearings to help restore your driving privileges.
- Help you obtain a Monitoring Device Driving Permit (MDDP) that lets you drive with a BAIID device installed (if required).
- Walk you through the full reinstatement steps after your suspension period expires (if required).
The sooner you act, the better your chances of minimizing the time you are without your driving privileges.
DUI Defense Strategies in Illinois
A DUI charge in Illinois does not guarantee a conviction. A DUI defense attorney can review the evidence and create a strategy to defend your rights and protect your future. Typical DUI defense strategies may involve:
Challenging the Traffic Stop
Law enforcement must have a legally valid basis to stop your vehicle. If the stop was not supported by reasonable suspicion — such as observing erratic driving, traffic violations, or signs of impairment — any evidence collected after the stop may be excluded from your case.
Questioning Field Sobriety Tests
Field sobriety tests can be unreliable. Things like health problems, anxiety, road surface, and weather can make these tests inaccurate. A DUI defense attorney may challenge whether these tests reliably show that you were impaired.
Challenging Chemical Test Results
Breathalyzers and blood tests must be properly administered, regularly calibrated, and conducted by trained personnel. If there are mistakes in test procedures, equipment maintenance, or the timing of the test, the BAC results can be called into question.
Challenging Observations of Impairment
Law enforcement reports typically list things like slurred speech, bloodshot eyes, and the smell of alcohol as signs of impairment. Your attorney can present alternative explanations for these signs that are not related to impairment.
Asserting Constitutional Violations
When your rights are violated — such as through an illegal search, a failure to issue Miranda warnings, or an unlawful arrest — your attorney can ask the court to exclude that evidence through a motion to suppress.
Negotiating for Reduced Charges
In some cases, your lawyer may be able to get the charges reduced to a lesser offense or work out sentencing agreements that soften the long-term impact on your record and life.

What to Do If You Are Charged with a DUI in St. Clair County, IL
The steps you take immediately after your DUI arrest in St. Clair County, IL can significantly affect your case and your ability to keep your driver’s license.
Do Not Plead Guilty Right Away
Many people assume they have no choice but to plead guilty after a DUI arrest. This is a mistake. The government must prove the charges beyond a reasonable doubt, just like any other criminal case. You should always consult a DUI lawyer before deciding how to move forward.
Do Not Consent to Chemical Tests Until Police Get a Warrant
These field sobriety and chemical tests help the state collect evidence to support their case. You can prevent the state from gathering this evidence by declining all tests until a judge signs a warrant. Even though police may say your license will be suspended for a year if you refuse, our St. Clair County, IL DUI defense attorneys can challenge that suspension in court.
Contact a DUI Lawyer Immediately
The sooner you get a DUI lawyer involved, the more opportunities you will have to fight the charges and protect your driving privileges. Delays can reduce your chances of a successful defense.
Preserve Any Evidence
Gather and preserve receipts, messages, or any documents that might support your version of events, such as where you were, what you had, or who can confirm your story.
Follow Your Lawyer’s Advice
DUI cases can proceed quickly and deadlines come fast. It’s essential to trust your attorney’s guidance and follow their strategy at every stage of the case.
