CBS News: A new survey reveals more than a quarter of adults admit they don’t always buckle up in the back seat. Research by the Insurance Institute for Highway Safety found that 91 percent of adults say they always wear their seat belt in the front seat, but only 72 percent are just as diligent in the rear.

People who don’t wear their seat belts account for about half of all deaths in car crashes each year, reports CBS News’ Kris Van Cleave. The report shows how effective seat belt laws and safety education have been in getting folks up front to buckle up – but not in the back.
