What health condition must a CDL driver be aware of to ensure safe driving?

Vision impairments are critical for a CDL driver to be aware of because driving commercially requires an acute ability to see clearly and respond effectively to road conditions and signage. Good vision is essential for the safe operation of large vehicles, as it impacts the driver's ability to judge distances, perceive motion, and recognize shapes – crucial skills when navigating highways, managing traffic, and executing maneuvers like turning or merging.

While headaches, seasonal allergies, and common colds can affect a driver’s comfort or minor focus, they are not as fundamentally critical to the act of driving as vision. Vision impairments can lead to serious safety issues, including the inability to see other vehicles, pedestrians, and obstacles, which can greatly increase the risk of accidents. Therefore, for a CDL driver, maintaining good vision is paramount to ensuring not only their own safety but also the safety of others on the road.
