What is the primary reason for using turn signals while driving a commercial vehicle?

Using turn signals while driving a commercial vehicle is primarily important for informing other drivers of your intended maneuvers. This communication is crucial due to the larger size and increased blind spots associated with commercial vehicles, which can make them less maneuverable and more difficult to see. By signaling your intended turns or lane changes, you provide essential information that allows other drivers to anticipate your actions, thereby enhancing safety on the road.

This practice is especially vital in urban environments or when sharing the road with other vehicles, as it helps to reduce the risk of accidents. While complying with legal requirements and enhancing visibility are factors associated with using turn signals, the core purpose remains focused on effective communication with other road users to promote safe driving practices.
