The FMCSA Medical Examiner Handbook provides information and guidance to the medical examiner who performs the commercial driver medical examination. Determining driver medical fitness for duty is a critical element of the FMCSA safety program. Specialists, such as cardiologists and endocrinologists, may perform additional medical evaluation, but it is the medical examiner who decides if the driver is medically qualified to drive.
