Driving a CMV is perhaps the most apparent safety-sensitive function, as it involves the operation of the vehicle itself and requires full attention and alertness from the driver. Any impairment or distraction during this activity can lead to dangerous situations.

Loading a CMV also falls under safety-sensitive functions. Proper loading ensures that cargo is secured and balanced, which is critical for safe operation. Improperly loaded vehicles can cause instability, increased stopping distances, or potential cargo shifts during transit, all of which pose significant risks.

Waiting for assistance with a disabled CMV is another safety-sensitive function. During this time, drivers must remain vigilant and aware of their surroundings to ensure their safety and the safety of others. The presence of a disabled vehicle can create hazards for both the driver and passing motorists.
