Most FAQ About DUIs in Illinois

Navigating Illinois DUI laws can be confusing and stressful. Whether you are worried about license suspension or jail time, understanding the statutes is the first step toward a strong defense.

What is the legal blood alcohol concentration (BAC) limit under Illinois DUI laws?

In Illinois, it’s illegal to drive with a BAC of 0.08% or higher for drivers over 21. However, Illinois DUI laws are strict; you can still be charged if your BAC is lower but your driving is impaired by alcohol, drugs, or cannabis. For commercial drivers, the limit is 0.04%, and for those under 21, it’s zero tolerance. As an aggressive DUI defense attorney with over 35 years of experience, I’ve successfully challenged BAC evidence in court.

2. What are the penalties for a first-time DUI offense in Illinois?

A first-time DUI in Illinois is typically a Class A misdemeanor, punishable by up to one year in jail, fines up to $2,500, court costs, and a minimum one-year driver’s license revocation. You may also face mandatory alcohol education, community service, and ignition interlock device requirements. Penalties escalate if your BAC was over 0.16% or if there was a child in the vehicle. With my 35+ years of experience fighting DUIs, I’ve helped clients avoid jail time and reduce charges—let’s build a strong defense for your case.

3. Can I refuse a breathalyzer or field sobriety test in Illinois?

Under Illinois’ implied consent law, refusing a chemical test (like a breathalyzer) after arrest results in an automatic statutory summary suspension of your license—typically 12 months for a first refusal, longer than if you fail the test (6 months). You can refuse field sobriety tests without immediate license penalties, but it may lead to arrest based on other evidence. I’ve aggressively challenged implied consent violations in court for over 35 years. If you’ve refused a test, reach out immediately to protect your rights.

4. What happens to my driver’s license after a DUI arrest in Illinois?

Upon arrest, Illinois imposes a statutory summary suspension: 6 months if you fail a chemical test, or 12 months if you refuse (for first offenders). This starts 46 days after arrest, but you can petition for a hearing to challenge it within 90 days. You may qualify for a Monitoring Device Driving Permit (MDDP) to drive with an ignition interlock. As a seasoned DUI defender with 35+ years in Illinois courts, I’ve won countless license reinstatement hearings—contact me to fight your suspension.

5. Is a DUI considered a felony or misdemeanor in Illinois?

Most first and second DUIs are Class A misdemeanors, but they become felonies (Class 4 or higher) on the third offense, or sooner if aggravating factors like bodily injury, a child passenger, or high BAC are involved. Felony DUIs carry mandatory prison time, steeper fines, and longer revocations. With my aggressive approach and 35+ years of experience, I’ve downgraded felonies to misdemeanors for clients. If your case involves felony charges, let’s discuss strategies to minimize the impact.

6. What are the DUI laws for drivers under 21 in Illinois?

Illinois has a zero-tolerance policy for underage drivers: Any BAC above 0.00% can result in a DUI charge, with penalties including license suspension for at least 6 months, fines, and possible jail time. Even possession of alcohol in the vehicle can lead to additional charges. As an experienced attorney who’s defended young drivers for over 35 years, I know how to challenge evidence like underage testing. If you’re under 21 and facing charges, contact me for a tailored defense.

7. Can I get a restricted driving permit after a DUI in Illinois?

Yes, first-time offenders may apply for a Monitoring Device Driving Permit (MDDP) after 30 days of suspension, allowing limited driving with a breath alcohol ignition interlock device (BAIID). For repeat offenders, a Restricted Driving Permit (RDP) might be available after a formal hearing. I’ve helped countless clients navigate these processes aggressively over my 35+ years in practice. If you need to get back on the road legally, reach out for expert guidance.

8. How long does a DUI conviction stay on my driving record in Illinois?

A DUI conviction remains on your Illinois driving record permanently, affecting insurance rates, employment, and future charges. However, court supervision (if granted) may not count as a conviction for record purposes. With my extensive experience—over 35 years fighting DUIs—I’ve secured supervision or dismissals to protect clients’ records. If you’re worried about long-term consequences, let’s explore options to keep your record clean.

9. What defenses can be used against a DUI charge in Illinois?

Common defenses include challenging the traffic stop’s validity, inaccuracies in field sobriety or chemical tests, medical conditions mimicking impairment, or violations of your rights during arrest. Illinois law requires probable cause for stops and proper test administration. As an aggressive defender with 35+ years of courtroom wins, I’ve used these strategies to get charges dropped or reduced. Every case is unique—contact me to evaluate the best defense for yours.
