DUI Charges in Cook County? Here’s What Happens Next

Getting charged with a DUI (Driving Under the Influence) in Cook County can be overwhelming. You’re likely facing court dates, potential license suspension, and even jail time. But what happens next—and what you do right now—can have a major impact on your future.
At Craig F. Miller Law Firm, we’ve represented clients across Cook County for over 40 years in DUI and criminal defense matters. Here’s a clear breakdown of what to expect after a DUI arrest in Illinois and how to protect your rights.
Step-by-Step DUI Process in Cook County
1. The Traffic Stop
A DUI usually begins with a police stop for suspected impairment or a traffic violation. If the officer suspects you’ve been drinking, they’ll administer a field sobriety test and/or a portable breath test (PBT).
2. Arrest and Chemical Testing
If the officer has probable cause, you’ll be arrested and taken to a police station for a
Breathalyzer or
blood test.
- Refusing this test can result in
automatic license suspension under Illinois’
Implied Consent Law.
3. Booking and Release
You’ll be fingerprinted and photographed. Depending on the situation, you may be released on bond or held until a hearing.
4. Statutory Summary Suspension
Regardless of criminal charges, your
driver’s license may be suspended starting
46 days after arrest unless you request a hearing within 90 days.
5. First Court Appearance (Arraignment)
You’ll enter a plea (guilty or not guilty). If you hire us before this, we’ll enter the plea for you and start preparing your defense.
6. Trial or Plea Deal
Depending on your case, we may fight the charges at trial or negotiate reduced penalties through a plea agreement.

Special Considerations in Cook County DUI Cases
- Zero Tolerance for Underage Drivers: Drivers under 21 face automatic suspension even with low BAC levels.

1-year disqualification, even for private vehicle arrests.
- Out-of-State Drivers: Illinois DUI laws still apply. You may face penalties in both states.
- Cook County Court System: We appear regularly in courthouses across the county, including Bridgeview, Markham, and the Daley Center.
Common DUI Defense Strategies
- Lack of probable cause for the traffic stop
- Inaccurate field sobriety tests or mishandled Breathalyzer administration
- Medical conditions that mimic intoxication
- Improperly calibrated equipment
- Unlawful questioning or Miranda rights violations
Every DUI case is unique. We build custom defenses tailored to your record, the police report, and evidence presented.
FAQs – DUI in Illinois
Q1: How long does a DUI stay on my record in Illinois?
Forever. Illinois does not allow expungement or sealing of DUI convictions.
Q2: Can I get court supervision for a first DUI?
Yes, but only once in your lifetime. Supervision prevents a conviction but still comes with fines and classes.
Q3: Will I lose my license automatically?
You can fight the
statutory summary suspension by requesting a hearing within 90 days. A lawyer can represent you at that hearing.
Q4: Can I refuse a Breathalyzer test?
Yes, but it triggers
automatic license suspension (12 months for first offense). Refusal can also be used as evidence in court.
Q5: How much does a DUI lawyer cost?
Fees vary based on case complexity, but fighting a DUI without a lawyer can cost far more in the long run. We offer free consultations to help you understand your options.
