Which is a major reason for enforcing seat belt use laws?

The enforcement of seat belt use laws is primarily aimed at reducing injuries and fatalities in traffic accidents. Seat belts are proven to be one of the most effective safety features in vehicles; they significantly decrease the likelihood of severe injuries or death during a collision. By requiring all vehicle occupants to wear seat belts, the law promotes a safer driving environment, ultimately leading to fewer injuries and fatalities on the roads.

While the other options address various aspects of traffic safety, none relate directly to the fundamental purpose of seat belt laws. For example, seat belt usage does not inherently prevent speeding, ensure proper sitting arrangements by itself, or directly lead to an increase in traffic stops. The core objective remains focused on enhancing passenger safety during vehicular travel.
