A bill which would require all backseat passengers to buckle up received a public hearing before the legislature's Transportation Committee yesterday.  Newtown Representative Mitch Bolisnky advocated for the bill.  He says having an unrestrained backseat passenger, that increases the chance of death for front seat riders by 20 percent.  While about 89 percent drivers and front passengers use seat belts, Connecticut is 1 of 22 states without a law requiring all backseat passengers to do that same.
