What is the protocol for using turn signals in commercial driving?

The correct response emphasizes the importance of signaling your intentions to change direction or lanes. Proper use of turn signals is a crucial aspect of safe driving, particularly in commercial vehicles where the size and handling characteristics may affect maneuverability. Signaling informs other road users of your intentions, which helps prevent accidents and enhances overall road safety. When a commercial driver indicates their intentions—whether it's turning, merging, or changing lanes—they are actively communicating with other drivers, cyclists, and pedestrians, ensuring that everyone is aware of the movement and can adjust their behavior accordingly.

Consistently using signals, regardless of whether other vehicles are present, is a fundamental rule of safe driving practice. This proactive communication fosters a safer driving environment and reduces the potential for misunderstandings on the road.
