DUI Evaluation in Illinois: What to Expect

What Is a DUI Evaluation?

A DUI evaluation (also called a substance abuse evaluation or alcohol/drug assessment) is a professional assessment required in nearly all Illinois DUI cases. The evaluation determines your level of substance use risk and recommends appropriate treatment or education. Courts rely heavily on these evaluations when deciding supervision conditions and sentencing.

After 25+ years defending DUI cases exclusively, Andy Sotiropoulos has guided thousands of clients through this process. How you prepare for and approach the evaluation can affect the treatment requirements you receive—and ultimately, your case outcome.

Risk Classifications

Illinois DUI evaluations categorize offenders into risk levels based on drinking history, BAC at arrest, driving record, and assessment questionnaires:

• Minimal Risk: Typically first offenders with lower BAC. Requires 10 hours of DUI Risk Education classes.
• Moderate Risk: Indicators of developing patterns. Requires 20+ hours of early intervention counseling.
• Significant Risk: Evidence of regular problematic use. Requires 40-75 hours of substance abuse treatment.
• High Risk: Indicators of dependency. Requires 75+ hours of treatment, potentially inpatient.

The classification you receive directly impacts the cost, time commitment, and requirements for completing supervision or probation. This is why preparation matters.

Where to Get Evaluated: DuPage County

In DuPage County (18th Judicial Circuit), the standard evaluation provider is:

• DuPage County Court Services
• 421 N. County Farm Road, Wheaton, IL 60187

• Cost: Approximately $200

Some DuPage County judges accept evaluations from private agencies. Andy can advise whether a private evaluation might be beneficial in your specific situation—sometimes the additional cost provides more flexibility in scheduling and assessment approach.

Where to Get Evaluated: Will County

In Will County (12th Judicial Circuit), evaluations are typically conducted through:

• Will County Adult Probation
• 57 N. Ottawa Street, Suite 100, Joliet, IL 60432
• Phone: (815) 727-8587

Private evaluation providers are also accepted in Will County. Your attorney can recommend providers who understand the local court's expectations.

What Happens During the Evaluation

A typical DUI evaluation takes 1-2 hours and includes:

• Clinical interview: Questions about your drinking history, frequency, patterns, and the circumstances of your arrest.
• Standardized questionnaires: Written assessments like the MAST (Michigan Alcohol Screening Test) or ASI (Addiction Severity Index) that score your risk level.
• Driving history review: Your Secretary of State driving abstract, including any prior DUI-related incidents.
• BAC at arrest: Your blood alcohol content at the time of testing is factored into the risk assessment.
• Personal history: Questions about employment, family, health, and any prior treatment.

How to Prepare

• Talk to your attorney first. Andy reviews each client's situation and provides specific guidance on how to approach the evaluation honestly while protecting your interests.
• Be honest but measured. Evaluators are trained to detect inconsistencies. Minimizing or exaggerating both work against you.
• Bring required documents: Photo ID, arrest paperwork, driving abstract (available from the Secretary of State).
• Don't attend under the influence. This should be obvious, but evaluators note signs of intoxication.
• Arrive on time. Late arrivals can be rescheduled, adding delays to your case.

If You Disagree With Your Classification

If you believe your risk classification is too high—perhaps based on a single high-BAC arrest with no history of alcohol issues—options exist. Your attorney can request a reassessment from a different provider or present the court with evidence supporting a lower classification. Andy has extensive experience challenging inappropriate classifications that would impose excessive treatment requirements.

Professional License Considerations

If you hold a professional license, your DUI evaluation results may become relevant to licensing board proceedings. How you handle the evaluation—and the treatment you complete—can demonstrate responsibility and compliance that may favorably influence board decisions. Andy coordinates DUI defense with professional license protection from the start.
