Under which code is the medical examiner's responsibilities outlined?

The responsibilities of the medical examiner in the context of commercial vehicle drivers are outlined under 49 CFR 391.43. This section of the Code of Federal Regulations specifically details the qualifications and processes that medical examiners must follow when conducting physical examinations of commercial motor vehicle drivers. It sets forth the standards for medical evaluations, which include determining the driver's ability to operate a commercial vehicle safely.

In addition, it emphasizes the necessity of adhering to the guidelines established by the FMCSA (Federal Motor Carrier Safety Administration) and ensuring that individuals meet the physical and medical criteria necessary for safe driving. This code is critical for maintaining public safety on the roads as it governs how medical professionals assess driver fitness and the overall health implications of operating large vehicles.

The other options relate to different aspects of the regulations concerning commercial drivers but do not specifically lay out the medical examiner's responsibilities. For instance, sections like 49 CFR 391.41 address general driver qualifications, while 49 CFR 391.64 discusses medical certification processes. However, it is 49 CFR 391.43 that directly details the medical examiner's duties and the specific standards to which they must adhere when evaluating drivers.
