What is the primary reason for wearing a seatbelt while driving a commercial vehicle?

The primary reason for wearing a seatbelt while driving a commercial vehicle is to reduce injury in case of an accident. Seatbelts are designed to secure occupants within the vehicle, preventing them from being thrown forward or ejected from the vehicle in a crash. This protective measure significantly lowers the risk of serious injuries or fatalities that can result from collisions.

While compliance with legal requirements and avoiding fines are important factors that motivate drivers to wear seatbelts, the ultimate purpose of a seatbelt is safety. Additionally, enhancing comfort is not a primary function of a seatbelt; instead, its main role in a vehicle is to provide crucial protection. Thus, the emphasis should always be on the life-saving benefits that seatbelts provide, especially when operating a large and potentially hazardous commercial vehicle.
