What is the purpose of a seatbelt?

A seatbelt is primarily designed to protect passengers in the event of a collision. When a car crashes or comes to a sudden stop, the forces involved can cause passengers to be thrown forward at high speeds. Seatbelts restrain occupants, reducing the risk of serious injuries by keeping them securely in their seats. This is a critical safety feature that minimizes the movement of the body during an impact, thus significantly lowering the likelihood of fatal injuries or severe trauma.

While other options mention reasons that may seem relevant, such as enhancing aesthetics or preventing theft, they do not address the fundamental life-saving purpose of a seatbelt. The necessity of wearing a seatbelt is emphasized in vehicle safety regulations and is a vital aspect of passenger protection in automotive travel.
