National Registry of Certified Medical Examiners
As of June 14, 2025, the Secretary of State is required to check the National Registry of Certified Medical Examiners (NRCME) for drivers certifying to Non-Excepted Interstate when issuing a Commercial Learners Permit (CLP) or Commercial Driver License (CDL).
Due to Federal Motor Carrier Safety Administration (FMCSA) requirements, Medical Examiner’s Certificates (MEC)s will only be accepted electronically from the National Registry.
Certified medical examiners must report results of all CMV drivers’ physical qualification examinations performed (including the results of examinations where the driver was found not to be qualified) to the National Registry by midnight (local time) of the next calendar day following the examination.
CDL and CLP holders certifying their driving type as Non-Excepted Interstate must have a valid MEC on file to operate a commercial motor vehicle. Please note that a paper copy of the MEC must still be presented to law enforcement when requested if you are certified as Non-Excepted Intrastate.
The National Registry is a FMCSA program and is not administered by the Michigan Department of State. For more information visit nationalregistry.fmcsa.dot.gov/ or call the FMCSA information line at 1-800-832-5660.
