DOT Physicals

Commercial motor vehicle drivers covered by federal rules must be medically certified as physically qualified to drive. A DOT physical is that exam, and the resulting medical examiner's certificate is what keeps a driver qualified.

Check the examiner first

Under 49 CFR 391.43, the exam must be performed by a medical examiner listed on FMCSA's National Registry of Certified Medical Examiners. An ophthalmologist or optometrist may handle the vision portion. Before you book, search the National Registry by city, state, or ZIP code to confirm your examiner is certified.

How often you need one

Federal rules require drivers to be re-examined and recertified at least every 24 months. Some drivers must be recertified at least every 12 months, including drivers with insulin-treated diabetes who were certified under FMCSA's diabetes standard and drivers certified under its alternative vision standard. A driver whose ability to drive has been impaired by an injury or illness also needs a new exam.

What it costs

DOT physicals are often flat-priced. Ask the clinic for its self-pay rate, and check whether your employer covers it. See the full Illinois cost guide.
