What is the main focus of the CDL requirements when it comes to driver health?

The main focus of the CDL requirements regarding driver health is ensuring physical and mental fitness for safe driving. This is crucial because commercial drivers operate large vehicles that can pose significant risks on the road if the driver is impaired or unfit to drive. The regulations typically mandate that drivers undergo medical examinations to assess their physical condition, including vision, hearing, and overall health, ensuring they can handle the demands of operating a commercial vehicle safely.

Maintaining physical and mental fitness encompasses not only being free from debilitating medical conditions but also requiring the ability to make quick decisions, stay alert, and manage stress effectively while driving. This focus on health is essential in preventing accidents and ensuring the safety of both the driver and others on the road.
