About the Exam
A Department of Transportation (DOT) physical examination must be conducted by a licensed "medical examiner" listed on the Federal Motor Carrier Safety Administration (FMCSA) National Registry. The term includes, but is not limited to, doctors of medicine (MD), doctors of osteopathy (DO), physician assistants (PA), advanced practice nurses (APN), and doctors of chiropractic (DC).
A DOT physical exam is valid for up to 24 months. The medical examiner may also issue a medical examiner's certificate for less than 24 months when it is desirable to monitor a condition, such as high blood pressure.
If the medical examiner finds that the person he/she examined is physically qualified to drive a commercial motor vehicle (CMV), the medical examiner will furnish one copy of the results to the person who was examined and complete a Medical Examiner's Certificate.
