Connecticut doesn't currently have a law requiring back seat passengers to be buckled up.  A proposal requiring seat belt usage has been introduced by Newtown Representative Mitch Bolinsky.  He says not using the safety device can turn back seat passengers into projectiles endangering others riding in the car.  A survey by the Insurance Institute for Highway Safety last year found 28 percent of respondents did not always wear a seat belt in the back of a car. The organization says that makes them eight times as likely as buckled rear-seat passengers to be injured or killed in a crash.
