By Janelle Stecklein/ CNHI State Reporter Apr 5, 2021 Apr 5, 2021 OKLAHOMA CITY â Despite bipartisan support, a measure that would have reinstated a controversial child seat belt law stalled in a House committee. Up until 2016, Oklahoma had a law requiring children ages 8 and older to be buckled up while riding in the back seat, but supporters of the requirement said lawmakers repealed it and they have been pushing for five years to get it reinstated. Oklahoma is now the only state in the country that doesnât require children to buckle up while riding in the back seat, said state Sen. Roland Pederson, R-Burlington, the Senate author.
