The Federal Motor Carrier Safety Administration (FMCSA) uses medical examiners (MEs) to conduct examinations and certify that the 6.1 million active interstate and intrastate commercial motor vehicle drivers meet the physical requirements for safety. The National Registry of Certified Medical Examiners (National Registry) allows qualified medical providers to become certified to serve as MEs in support of these efforts. Currently, FMCSA has certified over 69,000 MEs.
