What is the function of the CDL medical certification?

The function of the CDL medical certification is to ensure that the driver meets health standards necessary to operate a commercial vehicle safely. This certification is required to assess any medical conditions that could impair a driver's ability to control the vehicle, respond to emergency situations, or maintain focus on the road. Drivers must undergo a medical examination performed by a certified medical examiner, who evaluates factors such as vision, hearing, cardiac health, and neurological stability.

Maintaining these health standards is crucial for ensuring not only the safety of the driver but also the safety of passengers and other road users. A healthy driver is less likely to have incidents that could arise from medical issues, thus promoting safer roadways.
