How many deaths per year are caused by seat belts?

Seat belts are designed to save lives, but improper use or failure to wear them can lead to fatalities in accidents. While exact numbers can vary by region and year, it's estimated that around 10,000 to 15,000 deaths occur annually in the U.S. due to issues related to seat belt use, including being ejected from vehicles in crashes. However, the overall effectiveness of seat belts in preventing fatalities is significant, as they are credited with saving tens of thousands of lives each year.
