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. Illinois law also allows DUI charges if your BAC is 0.08% or more, regardless of whether you show obvious signs of impairment.
Driving under the influence of illegal drugs or prescription medications is also covered under Illinois DUI laws.
It’s important to know that you don’t have to reach the 0.08% BAC threshold to be arrested for DUI. Any noticeable impairment from alcohol, drugs, or their combination can still lead to DUI charges in Illinois.
Illinois DUI laws are found under 625 ILCS 5/11-501, which details the legal definition, prosecution process, and penalties for DUI in Illinois.
Types of DUI Charges in Jefferson 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 Jefferson County, IL courts:
First-Time DUI (Class A Misdemeanor)
A first DUI offense in Illinois is usually charged as a Class A misdemeanor. This charge carries potential penalties of up to one year in jail, fines reaching $2,500, at least a one-year license revocation, and mandatory alcohol programs.
Aggravated DUI (Felony)
A DUI can become a felony if certain aggravating factors are present. Examples include:
- Operating a vehicle while under the influence with a passenger younger than 16 years old.
- Causing serious injury or death while driving under the influence.
- Having a DUI history with three or more prior convictions.
- Being charged with DUI while driving with a suspended or revoked driver’s license.
The penalties for aggravated DUI are far more severe and can include prison sentences and extended loss of your driver’s license.
Repeat DUI Offenses
A second or third DUI conviction can lead to much steeper penalties. Additional jail time, longer license revocations, and stricter probation or supervision terms can apply.
DUI with a Minor Passenger
Having a child passenger in the vehicle during a DUI arrest can trigger enhanced punishments like mandatory community service, higher fines, and possible felony prosecution.
DUI Causing Injury or Death
If a DUI accident results in serious bodily injury, permanent disability, or death, you could face aggravated DUI charges and lengthy prison sentences.
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
Illinois law allows DUI charges if you drive under the influence of illegal drugs, prescription drugs, or over-the-counter medications that impair your driving ability.
CDL DUI
Commercial Driver’s License (CDL) holders face harsher DUI penalties in Illinois. The first CDL DUI offense can result in a one-year CDL disqualification, regardless of whether you were driving a commercial or personal vehicle. A second DUI conviction leads to lifetime CDL disqualification. The legal BAC limit for CDL drivers in commercial vehicles is just 0.04%, which is half the standard limit for non-commercial drivers.
DUI Penalties in Jefferson County, IL
The penalties for DUI in Illinois vary based on whether it’s your first, second, or an aggravated offense. The consequences can include jail time, fines, license suspension or revocation, and long-term impact on your driving record and insurance.

You may face increased insurance premiums, loss of employment, and long-term driver’s license restrictions.
Summary Suspension and License Reinstatement After a DUI in Jefferson County, IL
If you are arrested for DUI in Illinois, your driver’s license can be automatically Statutorily Summarily Suspended — even without a conviction. This process is triggered if you either fail or decline a chemical test, like 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: Automatic 12-month license suspension.
- Commercial Drivers: CDL holders can face immediate disqualification, even if the DUI occurred in a personal car.
You have the right to challenge the summary suspension by filing a Petition to Rescind. This must be done within 90 days of the notice of suspension or your first court date, whichever comes 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:
- File the paperwork to contest the suspension.
- Fight for your license at reinstatement hearings.
- Assist you in getting a Monitoring Device Driving Permit (MDDP), which may allow you to drive with a BAIID (if applicable).
- Help you complete the formal license reinstatement process once your suspension is over (if needed).
Taking fast action can significantly reduce the time you spend without a valid driver’s license.
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. Common DUI defense strategies include:
Challenging the Traffic Stop
Police officers must have a valid legal reason to stop you. Without reasonable suspicion — like erratic driving, visible impairment, or traffic violations — any evidence gathered after the stop may be thrown out.
Questioning Field Sobriety Tests
Field sobriety tests may produce unreliable results. A person’s medical issues, nervousness, road conditions, and bad weather can all affect test results. Your attorney may argue that these tests do not accurately reflect impairment.
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
Police reports often rely on subjective observations such as slurred speech, bloodshot eyes, or the smell of alcohol. Your defense attorney can argue that these signs were caused by something unrelated to DUI, like fatigue, allergies, or anxiety.
Asserting Constitutional Violations
If your rights were violated — such as illegal search and seizure, failure to read Miranda rights, or unlawful arrest — your attorney can file motions to suppress evidence that was improperly obtained.
Negotiating for Reduced Charges
When appropriate, your attorney may work to have the charges reduced to a lesser offense like reckless driving or to negotiate sentencing options that minimize the long-term impact on your life.

What to Do If You Are Charged with a DUI in Jefferson County, IL
The steps you take immediately after your DUI arrest in Jefferson 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. Like every criminal case, the state has to prove guilt beyond a reasonable doubt. 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. Police officers may warn you about an automatic one-year license suspension, but our Jefferson County, IL DUI lawyers can still fight that suspension in court.
Contact a DUI Lawyer Immediately
Getting a DUI lawyer involved immediately gives you more options to protect your license and challenge the case against you. Waiting can limit your options.
Preserve Any Evidence
Save receipts, text messages, or anything that might support your defense, such as proof of where you were, what you consumed, or potential witnesses.
Follow Your Lawyer’s Advice
DUI cases can proceed quickly and deadlines come fast. It’s critical to rely on your lawyer’s strategy and follow their instructions closely during every step.
Frequently Asked Questions About DUI in Illinois
What happens if you get a DUI in Illinois?
If you are arrested for DUI in Illinois, you face both a criminal charge and an automatic Statutory Summary Suspension of your driver’s license. First-time DUI penalties can include jail time, fines, license revocation, required alcohol classes, and a Breath Alcohol Ignition Interlock Device (BAIID).
Can you still drive after a DUI in Illinois?
Yes, it’s possible to keep driving after a DUI arrest by securing a Monitoring Device Driving Permit (MDDP) that requires BAIID use. It’s also possible to contest the summary suspension, but the court imposes strict filing deadlines you must follow.
Can a DUI be dismissed in Illinois?
Yes, it’s possible to have DUI charges dismissed if your lawyer successfully disputes the traffic stop, testing methods, or any constitutional issues. An experienced DUI defense lawyer will carefully assess your case to determine if dismissal is achievable based on your specific circumstances.
How do I get my license back after a DUI in Illinois?
Getting your license back depends on whether you were suspended or fully revoked. For suspensions, you may be eligible for a Monitoring Device Driving Permit or full reinstatement after completing the suspension period.
