Seat belt use is a crucial safety measure in vehicles. Wearing a seat belt helps to secure passengers in their seats, reducing the risk of injury during a crash. In many places, laws require all passengers to wear seat belts, and failure to do so can result in fines. Proper seat belt use involves placing the lap belt low across the hips and the shoulder belt across the chest. This positioning helps distribute the force of a collision more evenly across the body. Seat belts are designed to keep occupants safe, making them an essential part of vehicle safety.
