What must a driver carry during the operation of a Commercial Motor Vehicle (CMV) concerning the medical certificate?

The requirement for a driver operating a Commercial Motor Vehicle (CMV) is to carry the original medical examiner's certificate. This document serves as official proof that the driver has met the necessary health and safety standards to operate a CMV, as determined by a qualified medical examiner.

Carrying the original certificate ensures that law enforcement and regulatory agencies can validate the driver's medical fitness directly during inspections. In instances where the original certificate is not available, it may complicate matters related to compliance and regulatory checks. Therefore, possessing the original document is critical for demonstrating adherence to the Federal Motor Carrier Safety Administration (FMCSA) regulations.

Carrying a copy or a faxed version does not hold the same weight in legal terms as the original certificate. Additionally, not requiring any certificate at all is not compliant with the regulations set forth for CMV operators, leaving them exposed to penalties or operational restrictions. The original medical certificate is an essential document for any driver of a CMV to ensure both their safety and the safety of others on the road.
