Do you have to wear a shoulder seat belt in car?

In most jurisdictions, wearing a shoulder seat belt while seated in the front seat of a car is mandatory by law. Some might even require its usage in the rear seats. However, it's essential to note that these laws can vary by region, so it's always best to check the specific regulations in your location. The purpose of shoulder seat belts is to provide additional safety in the event of a collision by restraining the upper body and reducing the risk of serious injuries or fatalities.
