Which of the following conditions can impact a CMV driver's ability to operate a vehicle?

Musculoskeletal conditions can significantly impact a CMV driver's ability to operate a vehicle safely. These conditions can affect mobility, strength, and the overall capacity to perform necessary driving tasks effectively. For example, issues such as arthritis, back pain, or joint problems can hinder a driver's ability to react quickly, control the vehicle, and maintain the physical endurance required for long periods of driving.

In contrast, while mental health disorders can also affect driving abilities, they are not always as directly tied to physical capabilities as musculoskeletal issues. Seasonal allergies primarily cause symptoms like sneezing or watery eyes that might distract a driver but do not usually impair physical ability to the same extent. Skin conditions, while potentially uncomfortable, typically do not affect driving capabilities. Thus, musculoskeletal conditions stand out as having a more direct impact on a driver’s physical performance and safety on the road.
