Department of Transportation (DOT) or Commercial Driving License (CDL) physical examination is conducted by a licensed "medical examiner".

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 medical condition.

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.

You are required to have a physical exam and carry a U.S. Department of Transportation (DOT) medical certificate if:

• You operate a motor vehicle with a gross vehicle weight rating (GVWR) or gross combination weight rating (GCWR) or gross vehicle weight (GVW) or gross combination weight (GCW) of 4,536 kilograms (10,001 pounds) or more in interstate commerce.
  
  
• You operate a motor vehicle designed or used to transport more than 15 passengers, including the driver, in interstate commerce.
  
  
• You operate a motor vehicle designed or used to transport between nine and 15 passengers, for direct compensation, beyond 75 air miles from your regular work-reporting location, in interstate commerce.
  
• You transport hazardous materials in quantities requiring placards, in interstate commerce.

You must carry a current copy of your medical examination certificate with you when you drive.
