What Is a DOT Physical?
A DOT physical (also called a CDL physical) is the medical exam the Federal Motor Carrier Safety Administration (FMCSA) requires for commercial drivers. It confirms you're medically fit to operate a commercial vehicle safely. Only examiners listed on the FMCSA National Registry can perform it and issue your Medical Examiner's Certificate — and Dr. Sas is on that registry.

Equipped for the Exam
Your DOT physical includes vision, hearing, blood pressure, and a thorough physical exam. We keep the right diagnostic tools on hand so the visit is efficient, accurate, and done in one stop.
What to Bring
To keep your visit fast and set you up to pass, bring what applies to you:
The basics
- Your current driver's license or state-issued photo ID
- Glasses, contacts, or hearing aids, if you need them to pass the vision and hearing checks
- A full medication list — names, dosages, and the prescribing doctor's contact for every prescription, over-the-counter product, and supplement
- Your current DOT medical card, if you're renewing
If it applies to you
- Diabetes: recent Hemoglobin A1c (HbA1c) results and blood-sugar logs
- Heart conditions: a clearance letter and recent test results (such as an echo or stress test) from your cardiologist
- Sleep apnea: a recent CPAP compliance log showing 30–90 days of use

You'll leave knowing where you stand, and with your certificate in hand when you pass.
