According to the National Highway Traffic Safety Administration (NHTSA), in 2015, seat belt use in passenger vehicles saved an estimated 13,941 lives in the United States. Over the last two decades, great strides have been made to increase belt usage through legislation, education, and enforcement, and, as a result, the U.S. seat belt usage rate has now risen to 90.1 percent—however, nearly 27.5 million people still don’t buckle up.1 Data from NHTSA show that “nearly half (48%) of the 22,441 occupants killed in crashes in 2015 were unbuckled.”2
