Wearing a seatbelt while driving a commercial vehicle is crucial primarily because it reduces the risk of injury in the event of an accident. Seatbelts are designed to secure the occupant in their seat, preventing them from being thrown around the vehicle or ejected in a collision, which can lead to severe injuries or fatalities. In commercial vehicles, which are often larger and may carry heavier loads, the potential for significant impact in an accident increases, making seatbelt use even more essential for safety.

While the other choices touch on important aspects of driving, such as the legality of seatbelt use and potential distractions, the foremost concern in the context of commercial driving is ensuring the driver's safety. Seatbelts provide critical protection, mitigating the severity of injuries that may occur during an accident, thus emphasizing the importance of always being buckled up behind the wheel.
