If you answered yes to one or more of the above activities as the only operation in which you
drive, you operate in excepted interstate commerce and do not need a Federal medical
examiner’s certificate.
If you answered no to all of the above activities, you operate in non-excepted interstate
commerce and are required to provide a current medical examiner’s certificate (49 CFR
§
391.45), commonly referred to as a medical certificate. Most CDL holders who drive CMVs in
interstate commerce are non-excepted interstate commerce drivers.
If you operate in both excepted interstate commerce and non-excepted interstate
commerce, you must choose non-excepted interstate commerce to be qualified to operate
in both types of interstate commerce.
