Final answer:
Wearing a safety belt in a vehicle is required by law to prevent injuries during accidents and reduce societal burden, with failure to comply resulting in a traffic ticket.
Step-by-step explanation:
You are required to wear your safety belt in a moving vehicle, and failure to do so will result in a traffic ticket. This law is in place to protect individuals in the event of an accident and to minimize the burden on society in terms of medical and physical care for those who might become injured due to not wearing a seat belt. When a vehicle stops suddenly, as in the case with the woman transporting cupcakes, the cupcakes continue to move forward due to inertia until they collide with an object, in this instance, the dashboard. The seat belt acts as a restraint, exerting a force to bring an occupant to a halt safely, as would occur in a car crash where the car decelerates rapidly.
