DOT medical card in Illinois: physical, examiner and how long it lasts
In short: commercial drivers need a DOT physical from a medical examiner listed on the FMCSA National Registry. The certificate, often called a "DOT medical card", is valid for up to 24 months, or less when a condition needs monitoring.

Who can do the exam
The exam must be done by a licensed medical examiner listed on the FMCSA National Registry. That can include doctors of medicine (MD), doctors of osteopathy (DO), physician assistants (PA), advanced practice nurses (APN) and doctors of chiropractic (DC). Before you book, ask the clinic to confirm the examiner is on the National Registry.
How long it lasts
| Situation | Certificate length |
|---|---|
| Standard | Up to 2 years |
| High blood pressure, stable on treatment | 1 year |
| Heart disease | 1 year |
| Original diabetes and vision waiver program (391.64) | 1 year |
| Insulin and vision exemption programs | 1 year |
| Driving in an exempt intra-city zone | 1 year |
| Examiner decides a condition needs closer monitoring (for example diabetes or a sleep disorder) | Shorter, as set by the examiner |
After the exam
If you are physically qualified, the examiner gives you a copy of the results and completes a Medical Examiner's Certificate. Use the expiry estimate tool to plan your next exam, and check the date printed on your certificate.
Keeping your CDL record current
Ask your employer or the Illinois Secretary of State how your medical certification is recorded on your commercial driver's license.
