What is the primary purpose of a seatbelt?

• A. To accelerate the vehicle’s speed
• B. To keep passengers secure and reduce injury in a crash
• C. To prevent passengers from changing seats
• D. To ensure compliance with traffic laws

Answer: (B)

The primary purpose of a seatbelt is to keep passengers secure and reduce injury in a crash. When a vehicle is involved in an accident, the sudden deceleration can cause unbelted occupants to be thrown forward with significant force. Seatbelts are designed to restrain the body, limiting movement and helping to spread the forces of a collision across stronger parts of the body, such as the chest and pelvis. This restraint reduces the risk of serious injuries or fatalities by keeping passengers in their designated seating positions and preventing them from being ejected from the vehicle. While other options touch on relevant aspects of driving and safety, they do not capture the critical life-saving function that seatbelts perform in the event of a crash. For example, accelerating a vehicle's speed is not a function of seatbelts, and while preventing the change of seats may be a secondary benefit, it is not the primary design intent. Similarly, compliance with traffic laws, while important, is not the primary role of a seatbelt. Seatbelts are fundamentally about protecting passengers and improving survival rates during motor vehicle incidents.
