What is the main purpose of wearing seat belts?

Answer: B — To keep passengers safe in case of an accident

The primary purpose of wearing seat belts is to keep passengers safe in the event of an accident. Seat belts are designed to restrain occupants and prevent them from being thrown from the vehicle or colliding with interior parts of the car during a sudden stop or crash. They significantly reduce the risk of injury or death because they help to distribute the force of a collision across the stronger parts of the body. Additionally, wearing a seat belt is particularly effective in preventing ejection from the vehicle, which is often fatal. While factors like comfort and legal compliance may be secondary considerations, they do not represent the main purpose of seat belts. Enhancing passenger comfort is not a function of safety equipment; it is more about the design and amenities of the vehicle. Although avoiding a ticket and complying with vehicle design are important reasons to wear a seat belt, they are not the fundamental reasons for their existence compared to the primary safety function that seat belts serve.
