What documents must CMV drivers maintain regarding their medical certifications?

CMV drivers are required to maintain a copy of their medical certification and any relevant medical documents because these records demonstrate that they meet the Federal Motor Carrier Safety Administration (FMCSA) standards for medical fitness to drive. This ensures that they are physically capable of operating a commercial motor vehicle safely and helps protect not only the driver but also the general public on the road.

The medical certificate serves as proof that the driver has undergone the necessary medical evaluations, including vision and hearing tests, and has been cleared for the physical demands of driving a commercial vehicle. Keeping this documentation up-to-date is essential, as drivers must present it during inspections or if requested by authorities.

In contrast, the other options include documents that do not pertain directly to the medical fitness requirements set forth for CMV drivers. Traffic violation records relate to a driver’s compliance with traffic laws, insurance policies are necessary for financial responsibility but not related to medical fitness, and driving logs track driving hours and rest periods rather than health status.
