◆ Illinois Law
A first DUI offense is defined and penalized under 625 ILCS 5/11-501 as a Class A misdemeanor. Court supervision — the outcome that keeps a conviction off your record — is authorized under 730 ILCS 5/5-6-1 and is available only once in a lifetime for DUI in Illinois.

A First DUI Is Serious—But Manageable
If this is your first DUI, you're probably terrified about what happens next. That's normal. But here's the truth: most first-time offenders avoid the worst outcomes with proper legal help. Jail time is rare, keeping your license is usually possible, and court supervision can keep a conviction off your record.
The key is acting quickly and getting experienced representation. With 3,000+ DUI cases defended over 25+ years—handling nothing but DUI cases—Andy Sotiropoulos has helped countless first-time offenders protect their futures. As a State Delegate to the National College for DUI Defense, Andy stays current on every defense strategy and legal development that could benefit your case.
If you were arrested in DuPage County, your case will be heard at the DuPage County Courthouse in Wheaton. Will County cases go through the courthouse in Joliet. Andy knows these courts, the prosecutors, and the judges—and that matters when negotiating outcomes for first-time offenders.
First DUI Penalties in Illinois
- Charge Level: Class A Misdemeanor
- Possible Jail: Up to 1 year (rarely imposed for first offense)
- Fines: Up to $2,500 plus court costs and fees
- License Suspension: 6 months (if you took the test) or 12 months (if you refused)
- Alcohol Education: Mandatory DUI Risk Education classes
- Court Supervision: Available for first offenders (keeps conviction off record)
Critical Deadline: You have 90 days from the notice (usually served at your arrest) to request a hearing to fight your license suspension. Miss this deadline and you lose the opportunity. Learn more about the 90-day deadline.
Court Supervision: Your Best Outcome
For first-time DUI offenders, court supervision is often the best possible outcome. If you complete supervision successfully:
- No conviction appears on your criminal record
- You can honestly say you've never been convicted of DUI
- Employment background checks won't show a DUI conviction
- Your professional license is protected (in most cases)
Supervision typically requires completing alcohol education, paying fines and fees, possible community service, and staying out of trouble for the supervision period. It's work—but it's worth it. Supervision is only available once in your lifetime for DUI, which is why getting it right the first time matters.
In DuPage County, the 18th Judicial Circuit typically requires a DUI evaluation through DuPage County Court Services at (630) 407-8384 before supervision can be granted. Andy can guide you through this process and advise on how to present yourself favorably during the evaluation.
What to Do in the First Week After a First DUI Arrest in Illinois
In the first week after a first DUI arrest in Illinois, do four things: request a judicial hearing to challenge your statutory summary suspension, write down everything you remember about the stop while it is still fresh, keep every document the police gave you, and talk to a DUI attorney before your arraignment. The 90-day window to request that hearing runs from the notice of suspension you were served, and it is the one deadline in a first DUI case that closes on its own whether or not anyone reminds you.
- Request the judicial hearing. Illinois law gives you 90 days from the notice of statutory summary suspension to make a written request for a judicial hearing. Miss it and the suspension stands unchallenged. More on the 90-day deadline.
- Write down what happened. Where you were coming from, what the officer said, what you were asked to do at the roadside, the weather and the surface you stood on, and whether you took or refused the test. Field sobriety and breathalyzer evidence is challenged on exactly these details, and memory fades faster than the case moves.
- Keep every piece of paper. The citations, the notice of summary suspension, any receipt for a seized license, and the bond paperwork. The dates on those documents are what set your timeline.
- Check your professional obligations. If you hold a professional license, your board may require you to report the arrest independently of the criminal case. See professional license defense.
- Talk to an attorney before arraignment. Arraignment is your first court appearance and where you enter a plea. Court supervision is not available to a defendant who has previously been convicted of, or assigned supervision for, DUI, so a first offense is the one chance to keep a conviction off your record - and that strategy is set early, not at the end.
Professional License Concerns
If you hold a professional license—medical, legal, financial, teaching, CDL, or aviation—a first DUI creates additional urgency beyond the criminal case. Many licensing boards, including IDFPR, require self-reporting of arrests within 30 days. How you handle the criminal case directly affects whether your licensing board takes action against your career.
Andy handles DUI defense for professionals across every field. Learn more about how DUI affects your specific profession: healthcare professionals, attorneys, financial professionals, educators, or all professional license defense.
Keeping Your License
Most first-time offenders can keep driving through the Monitoring Device Driving Permit (MDDP) program. This requires installing an ignition interlock device in your vehicle, but allows unlimited driving—to work, school, anywhere.

What Happens Next
The DUI court process in Illinois typically includes:
- Arraignment: Initial court appearance where you enter a plea
- Discovery: Your attorney reviews evidence against you
- Motions: Challenges to evidence or procedures
- Negotiation: Discussions with prosecutor about resolution
- Resolution: Trial, plea agreement, or dismissal
The process typically takes several months. During this time, your attorney is working to get the best possible outcome.
Why You Need an Attorney
A first DUI may seem "minor," but the consequences last a lifetime. Illinois has no expungement for DUI convictions—once convicted, it's permanent. Without proper representation, you may miss defense opportunities, fail to protect your license, or end up with a conviction that could have been avoided.
Andy Sotiropoulos handles nothing but DUI defense—no other criminal cases, no personal injury, no family law. That singular focus over 25+ years and 3,000+ cases means he's seen every version of a first DUI case and knows exactly where to find weaknesses in the prosecution's evidence. From challenging breathalyzer results to questioning field sobriety test procedures, every angle gets examined.
The consultation is free. In one conversation, Andy can tell you what you're facing and what can be done about it. Available evenings and weekends—because DUI arrests don't wait for business hours.

Frequently Asked Questions
What happens with a first DUI in Illinois?
A first DUI in Illinois is a Class A misdemeanor. Penalties can include up to 364 days (just under one year) in jail, fines up to $2,500, 6-month license suspension, and mandatory alcohol education. However, many first offenders avoid jail and may qualify for court supervision that keeps the conviction off their record.
Will I go to jail for my first DUI?
Most first-time DUI offenders in Illinois do not go to jail, especially with proper legal representation. Jail is more likely if there were aggravating factors like an accident, high BAC, or a minor in the vehicle. An experienced attorney can work to avoid jail time.
What is court supervision for DUI in Illinois?
Court supervision is essentially probation that, if completed successfully, results in no conviction on your record. You must complete requirements like alcohol education, community service, and fees. Supervision is only available once in your lifetime for DUI.
How long does a first DUI stay on your record in Illinois?
A DUI conviction stays on your record permanently in Illinois—there is no expungement for DUI. However, if you receive court supervision and complete it successfully, no conviction appears on your record. This is why fighting for supervision is so important.
Will I lose my license for a first DUI?
You face a 6-month statutory summary suspension for failing breath tests or 12 months for refusing. However, you may be eligible for a Monitoring Device Driving Permit (MDDP) that allows you to drive with an ignition interlock device. You have 90 days to challenge the suspension.
Can a first DUI be dismissed in Illinois?
Yes, a first DUI can be dismissed in Illinois when the evidence does not support the charge. Common grounds include an unlawful traffic stop, improperly administered field sobriety tests, a breathalyzer that was not calibrated or maintained correctly, or constitutional violations in how the stop or arrest was conducted. Not every case has these issues, but an experienced DUI attorney will examine every element of your case for defensible problems. Andy Sotiropoulos has obtained dismissals for first-time DUI defendants throughout DuPage, Will, Cook, and Kane Counties by identifying weaknesses the prosecution cannot overcome.
Can a first DUI be expunged in Illinois?
A DUI conviction cannot be expunged or sealed in Illinois, regardless of whether it is a first offense. It stays on your criminal record permanently. This is precisely why court supervision matters for first-time offenders: court supervision is not a conviction. If you complete supervision successfully, no conviction ever enters your record - and there is nothing to expunge because the charge was never converted to a conviction. Charges that are dismissed outright are eligible for expungement. An attorney who gets supervision or dismissal for a first DUI is protecting you from a permanent record problem.
Do I need a lawyer for my first DUI in Illinois?
You are not legally required to have an attorney, but going without one for a first DUI in Illinois is a serious risk. A DUI conviction cannot be expunged. Supervision is only available once in your lifetime. Breathalyzer and field sobriety evidence has specific legal standards for admissibility that most defendants do not know how to challenge. The 90-day deadline to contest your license suspension is unforgiving. And prosecutors in DuPage, Will, and Cook Counties are experienced - they do not offer better outcomes to defendants who represent themselves. A DUI defense attorney who handles these cases every day knows where to look for problems in the State's evidence and how to protect your record in the specific court where your case is pending.
How long does a first DUI case take in Illinois?
A first DUI case in Illinois typically takes several months to resolve. The process generally moves through arraignment, where you make your first court appearance and enter a plea; discovery, where your attorney reviews the State's evidence; pretrial motions that challenge evidence or police procedures; negotiation with the prosecutor; and finally resolution by plea agreement, dismissal, or trial. The exact timeline depends on the court, the complexity of the evidence, and whether the case goes to trial.
Do I have to complete a DUI evaluation or alcohol classes for a first DUI in Illinois?
For a first DUI in Illinois, a professional alcohol and drug evaluation and mandatory DUI Risk Education classes are typically part of the process, and courts generally require the evaluation before granting court supervision. Court supervision, the outcome that keeps a conviction off your record, is available only once in a lifetime for DUI in Illinois, so completing these requirements on time is often central to a first-offense strategy.
What should I do first after a first DUI arrest in Illinois?
Request a judicial hearing to challenge your statutory summary suspension, write down everything you remember about the traffic stop, keep every document the police gave you, and talk to a DUI attorney before your arraignment. Illinois law gives you 90 days from the notice of statutory summary suspension to make a written request for that hearing, and it is the one deadline in a first DUI case that closes on its own. Everything else in a first offense - the plea, the evaluation, the fight over the breath test - can still be shaped later. The suspension challenge cannot.
