Lightning strikes, shark attacks, snake bites – a lot of things can kill you…but if you get in a crash without a seat belt you only have a 50/50 chance of surviving. Don’t play the odds. Seat belt use is required by law for a reason: In 2015, seat belts saved an estimated 13,941 people from dying. From 2011 to 2015 seat belts saved nearly 64,000 lives.
