What increase in safety can be achieved by using proper seat belts in a commercial vehicle?

Reduced visibility
Minimal impact during collision
Increased risk of ejection
Improved protection of vehicle occupants

The correct answer is: Improved protection of vehicle occupants

Using proper seat belts in a commercial vehicle significantly enhances the protection of vehicle occupants during a crash. Seat belts are designed to keep individuals securely restrained, preventing them from being thrown around inside the vehicle or ejected from it upon impact. This function greatly reduces the risk of injuries and fatalities by ensuring that occupants remain in a controlled environment, with the safety features of the vehicle—such as airbags—more effectively deployed during collisions. The correct answer highlights the proactive role seat belts play in safeguarding the lives of those within a vehicle, which is essential for any operator of commercial vehicles to understand. The other options do not relate to the primary benefits of seat belt use; for instance, proper seat belts do not reduce visibility, they actually increase safety rather than pose risks of ejection, and they mitigate rather than minimize impact injuries, making the justification for the choice clear.
