The National Registry of Certified & Medical Examiners Mission Statement
"The primary mission of the National Registry of Certified Medical Examiners is to improve highway safety by producing trained, certified medical examiners who can effectively determine if a commercial motor vehicle driver's health meets Federal Motor Carrier Safety Administration standards."
Purpose of Physical Examination
The general purpose of the history and physical examination is to detect the presence of physical, mental, or organic conditions of such character and extent as to affect the ability of the driver to operate a commercial motor vehicle (CMV) safely. This examination is for public safety determination and is considered by the Federal Motor Carrier Safety Administration (FMCSA) to be a “medical fitness for duty" examination.
