Medical examiners (ME) are responsible for determining whether interstate drivers of commercial motor vehicles (CMVs) are medically qualified.
Medical professionals who perform DOT-required physical evaluations of drivers are required to meet Federal Motor Carrier Safety Administration (FMCSA) requirements.
Only medical examiners who are listed on the National Registry are authorized to conduct DOT-required physical examinations for interstate commercial motor vehicle drivers. Additionally, medical examiners are required to know and apply the FMCSRs, DOT protocols, medical guidelines, studies, and Medical Advisory Criteria. This is found in 391.43(c).
ME vs. MRO. Many confuse the term medical examiner with medical review officer (MRO). A medical review officer is a licensed physician who is responsible for receiving and reviewing laboratory results generated by an employer’s drug testing program and evaluating medical explanations for certain drug test results. They are not interchangeable terms.
