The National Registry of Certified Medical Examiners (National Registry) was developed and implemented under the authority of Section 4116(a) of the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA‐LU) (codified at 49 U.S.C. § 31149) and is managed and maintained by the Federal Motor Carrier Safety Administration (FMCSA). The Federal Motor Carrier Safety Regulations (FMCSRs) require that commercial motor vehicle (CMV)1 drivers comply with physical qualification requirements and be examined and certified by a medical examiner (ME) at least once every two years. The National Registry ensures that MEs who perform Department of Transportation (DOT) driver medical examinations are properly trained and certified by FMCSA to do so. The National Registry maintains personally identifiable information (PII) for each ME candidate applying for ME certification, ME’s administrative assistants and third parties who are registering on the National Registry, and of CMV drivers examined by a certified ME. FMCSA published a final rule on April 20, 2012 (77 FR 73129), to establish and maintain a National Registry of Certified Medical Examiners. FMCSA posted a Privacy Impact Assessment (PIA) of the final rule on the DOT privacy program website on August 20, 20122. FMCSA published the Medical Examiner’s Certification Integration Notice of Proposed Rulemaking (NPRM) on May 10, 2013 (78 FR 24104), a follow‐on rule to the National Registry final rule. FMCSA posted a PIA in support of the proposed rule in the docket on July 2, 20133.
