Illinois evaluates how a medical condition affects the ability to drive, using reports, vision measurements and examinations when necessary. A diagnosis does not answer every licensing question by itself. This guide explains self-reporting, the current medical form, family referrals, restrictions and the steps to take when Driver Services requests additional evidence.

When a condition must be reported
The Secretary of State's medical and vision instructions cover conditions that may cause loss of consciousness or impair safe vehicle operation, as well as medications that may interfere with driving. Illinois requires notification within 10 days after becoming aware of such a condition (checked October 20, 2026). Waiting for the next license renewal can therefore leave the reporting obligation unmet.
Describe the driving effect accurately when discussing the report with your treating professional. Relevant information can include episodes of impaired awareness, difficulty using the controls, changes in judgment, or medication side effects. A driver should not alter prescribed treatment simply to obtain a favorable licensing statement. Instead, the professional needs an accurate account of the condition, its treatment and whether the person can safely perform the driving task.
If the condition is already in the state's follow-up program, another medical report is required at renewal. Removal from follow-up requires a final report stating that the condition no longer exists. A driver who feels better but has not supplied that evidence should not assume the reporting entry has disappeared.
Use the current Medical Report form
The February 2026 edition of Medical Report for Conditions That May Impair Driving Safely, DSD DC-163 asks whether the applicant is medically and mentally fit to drive. Each listed condition needs a yes-or-no response. It also requests medications and doses, adverse effects, compliance with treatment, and whether the condition is controlled.
The form accepts a licensed physician, including an MD or DO, or a nurse practitioner or physician assistant. Its instructions exclude signatures from chiropractors, podiatrists, residents, fellows, interns, registered nurses and licensed practical nurses. The signer must supply the required professional information and license number. Do not assume a hospital discharge summary or a letter signed by a different category of practitioner will satisfy the prescribed certification.
The completed medical report remains valid for three months, stated on the form as 90 days (checked October 20, 2026). Plan the examination around the requested submission or renewal so the document has not aged out before it is used. If other professionals are treating relevant conditions, obtain their fitness statements or reports as directed by the form. A missing specialty assessment can leave the central driving question unanswered even when the main form is signed.
Understand what questions about episodes mean
The report asks about events during the preceding six months that caused loss of consciousness or an inability to operate safely, including the most recent occurrence. That question is a request for clinical history. It should not be read as a universal six-month seizure-free rule applying to every Illinois driver or every condition.
Document the event dates, treatment changes and current professional assessment, then follow the specific instructions issued for the licensing review. Decisions can involve a restriction, further examination or additional medical information. The driver's license application and renewal information supplies the broader licensing process, but a routine renewal cannot substitute for an unresolved medical determination.
Vision reports and restrictions
An eye professional can use the Vision Specialist Report, DSD X-20 to document acuity and visual fields. The current form recognizes MD, DO and optometrist signatures and rejects stamped signatures. It is valid for six months from the examination (checked October 20, 2026), a different validity period from the general medical report.
The ordinary acuity standard is 20/40 with or without correction. Acuity of 20/41-20/70 limits the driver to daylight operation. A field of at least 140 degrees supports an unrestricted license, but the form also addresses a qualifying monocular field with outside-mirror restrictions. Consequently, a single field measurement should be assessed using the complete form rather than treated as an automatic rejection based on the unrestricted standard alone.
Tell the specialist whether you use corrective lenses or a telescopic arrangement and whether you are seeking a change to an existing restriction. Telescopic licensing involves additional requirements and testing. Driver Services must approve that authority; purchasing the equipment does not expand a license. Bring the finished specialist report to the facility handling the licensing examination and use the prescribed corrective equipment during testing and driving.
Reports from relatives after July 2026
The immediate-family reporting process began under the Road Safety and Fairness Act on July 1, 2026. A spouse, parent, grandparent, child or sibling may report a legitimate medical or driving concern. The process applies to licensed drivers of any age, and reports cannot be anonymous.
A relative should supply specific observations that help the Medical Review Unit evaluate driving ability. Examples include unexplained vehicle damage, failure to react to pedestrians or getting lost on familiar routes. A report is made under penalty of perjury, and the state reviews it before deciding whether further evaluation is justified. The family form is accessed through the Secretary of State's reporting page; use that agency entry point to reach the current submission service.
Some older passages on the medical webpage identify only physician, police and judicial referrals. The newer family process expands those routes. The 2026 implementation explanation should be read with those older paragraphs so an eligible relative is not incorrectly told that direct reporting is unavailable.
Responding to a notice from Medical Review
When the state requests a medical or vision report after a family referral, its published procedure generally allows 20 days for the documentation (checked October 20, 2026). Testing notices describe three scheduled examination dates, followed by a 10-day grace period after the third date (checked October 20, 2026). The actual notice identifies the requirements for your case, and failure to comply can cause cancellation.
Read whether the request calls for medical evidence, vision evidence, testing, or a combination. Contact the examining professional promptly with the actual form and notice. Keep a complete copy of the submission and any confirmation, then follow up with Medical Review if the status is uncertain. Sending a report is a step in the review; it is not permission to ignore an existing cancellation or a restriction already printed on the license.
Review of a medical licensing decision
Medical decisions have specialized review procedures. The medical-review definitions in the administrative code describe review by a three-member Medical Review Panel before eligibility for a formal medical hearing under that subpart. This medical route should not be confused with an ordinary request for relief following traffic convictions.
Use the decision's review instructions and contact the Department of Administrative Hearings to identify the appropriate next step. A useful response addresses the specific medical finding or missing evidence instead of merely explaining that driving is convenient. If an examination requires an accommodation, arrange it with the facility in advance and explain the practical assistance needed.
Communication assistance and identification alternatives
Illinois offers communication-related license designations, including J88 for deafness or hearing difficulty, J89 for aphasia and J91 for a mental disability affecting communication. Some designations require medical certification. Their purpose is to help an officer understand communication needs; they do not establish that a person is medically unfit to drive.
The Person with a Disability Identification Card application supports a separate identification program. Eligible people with specified developmental or mental disabilities may also obtain a DHS communication wallet card. Someone unable to travel to a facility can explore the homebound ID procedure, particularly when a medical condition has ended driving but identification is still needed.
The statewide Blue Envelope Program is scheduled to launch January 1, 2027. As of this guide's October 2026 review, that statewide launch is still in the future, although local programs exist. The envelope will help communicate needs during a traffic stop; it will not replace a license, registration, insurance evidence or medical approval.
Commercial medical certification is separate
A person who also drives commercially must review the Illinois CDL medical-certification instructions. Commercial self-certification and examiner reporting address the commercial qualification record. An ordinary DSD DC-163 report does not, by itself, provide the Medical Examiner's Certificate required for the applicable commercial operation. Conversely, holding commercial medical certification does not excuse a separate Illinois medical-review notice.
Frequently Asked Questions
Do I wait until renewal to tell Illinois about a new condition affecting driving?
Illinois requires notice within 10 days of awareness of a covered condition or impairing medication, so an upcoming renewal is not the only reporting trigger (checked October 20, 2026).
Can a nurse practitioner sign my Illinois driving medical report?
The current DSD DC-163 accepts a nurse practitioner or physician assistant as well as an MD or DO, provided the report meets its certification requirements.
Does the question about the last six months create an automatic waiting period after every episode?
It collects the recent history needed for an individualized review and should not be converted into a blanket clearance rule for unrelated diagnoses.
Will a complaint from my sister be shared with my insurer?
The family reporting instructions describe the complaint as confidential, although an insurer obtaining your driving record may see a resulting licensing action.
Is a communication designation the same as a medical cancellation?
A designation alerts law enforcement to communication needs, whereas a cancellation is an action affecting the authority to operate a vehicle.
Can an approved commercial medical examination answer an ordinary medical-review request?
The commercial examination and the state review may require different forms and findings; submit the particular evidence requested by the Medical Review Unit.
