Prescription Drug DUI Charge in Will County
Yes, you can be charged with DUI for a drug a doctor prescribed. Illinois law says being legally allowed to use a drug is not a defense. The state has to show the drug left you unable to drive safely, unless the charge is about unlawful use of a controlled substance.
Your deadlines
- Day 46. Your statutory summary suspension starts, counted from the day you got the notice.
- Day 90. The last day to file a petition to rescind that suspension.
What happens next
- An officer stops you for a driving problem and thinks something other than alcohol is involved.
- You may be asked for a blood or urine sample.
- The sample goes to a lab for analysis.
- You receive a court date at the Will County Courthouse in Joliet.
- Jeff asks for the lab file, the officer's notes and any video.
The three parts of the law
Section 11-501(a) lists several ways to commit DUI. Three of them deal with drugs.
| Subsection | What the state must show |
|---|---|
| (a)(4) | You were under the influence of a drug, or drugs together, to a degree that made you incapable of driving safely |
| (a)(5) | You were under the combined influence of alcohol, drugs or intoxicating compounds, to a degree that made you incapable of driving safely |
| (a)(6) | Any amount of a controlled substance, intoxicating compound or methamphetamine in your breath, blood, other bodily substance or urine, from unlawful use |
The first two need proof of impairment. The third does not need impairment, but it needs unlawful use.
What a prescription does and does not do
Subsection (b) of the statute says that being legally entitled to use a drug is not a defense to a DUI charge. A prescription alone will not end the case.
It still matters. A charge for a drug you took lawfully points toward (a)(4), which needs proof that the drug left you unable to drive safely. The wording of (a)(6) covers unlawful use. So the prescription changes which part of the law the state has to use, and what it must prove.
Bring every bottle to your first meeting, with the dates you took each one.

Why these cases are different from alcohol
The 0.08 rule belongs to alcohol under (a)(1). The drug subsections work differently. Two of them turn on whether you could drive safely, and that is a question of proof, not a single number.
- Combinations of medicines can be charged under (a)(4) or (a)(5).
- Alcohol plus a drug can be charged under (a)(5) even when the alcohol reading is under 0.08.
- Subsection (a)(4) says any other drug, so the label on the bottle does not decide the question.
What to bring and what to expect
Bring the pill bottles, pharmacy printouts, the names of your prescribing doctors and a list of everything you took in the 24 hours before the stop, including over the counter products and supplements. Jeff may ask for a letter from your doctor about the dose and any warnings you were given.
If a lab tested your blood or urine, Jeff will request the lab file and go through it with you, line by line. He will also ask what the lab tested for, and what level it treated as a positive result.
What is at risk
A first DUI under subsection (a) is a Class A misdemeanor, the same as an alcohol case. The Secretary of State must revoke the license of a person convicted. A court can order an evaluation, treatment, and a victim impact panel. A blood test showing a controlled substance from unlawful use can also bring a 6 month statutory summary suspension for a first offender, and refusing a test brings 12 months.
How Jeff defends this charge
- He asks the state to prove impairment, not just the presence of a medicine.
- He reads the lab report for the method used, the cutoff and the chain of custody.
- He looks at your medical history and dosing, with your permission, to show what you took and when.
- He reviews the driving and the roadside evidence for signs that fit a medical condition instead of a drug.
- He checks whether the officer had a lawful reason for the stop and the blood draw.
He does not promise an outcome. He tells you honestly where the case is strong and weak.

Questions people ask about prescription drug dui
Short answers first. Jeff McCarthy reviews every answer on this page.
Yes. Section 11-501(b) says that being legally entitled to use a drug is no defense to a DUI charge. The state still has to meet the terms of the subsection it charges.
Under (a)(4), it means a drug or combination of drugs affected you so much that you were incapable of safely driving.
The statute lets police test blood, breath, other bodily substance or urine. The tests are analyzed under standards set by the Illinois State Police, and you can ask for full information about them.
Under (a)(6), any amount of a controlled substance from unlawful use can be charged without proof of impairment. A drug taken lawfully falls under the impairment rules.
Yes. Subsection (a)(5) covers the combined influence of alcohol and drugs, even if the alcohol alone is under the limit.
Yes. Bring the bottles, the dates and your doctor's name. They help show what you took and what it was meant for.
