Cabin John, MD DOT Physical - What You Need to Know
A DOT physical is an all-encompassing medical check mandated by the Department of Transportation for every commercial motor vehicle (CMV) driver. This assessment is crucial to verify that professional drivers are physically, mentally, and emotionally prepared to operate large vehicles safely on public roads. Conducted by a certified medical examiner from the National Registry of Certified Medical Examiners, passing this exam grants drivers a DOT medical certificate (also known as a DOT medical card), required to keep a valid CDL license in accordance with FMCSA regulations. If another DOT agency regulates you and you need help finding out which DOT physical you require, please call us at 800-221-4291.
During your exam, the medical examiner will complete a thorough health assessment to determine if you meet the Federal Motor Carrier Safety Administration (FMCSA) medical standards. The process typically includes:

Customer Reviews
Saved My CDL!
Time was running out before my Cdl got downgraded because of a violation I had on clearinghouse. I couldn't find an employer to send me for my return to duty test, but these guys had my test scheduled and done in the same day! They saved my cdl. Thank you again!
