The state that was the first to pass car-safety seat requirements for children almost 40 years ago has sent a bill to the governor that would require toddlers to ride in rear-facing seats for an additional year.

Democratic Rep. John Ray Clemmons of Nashville said Monday that the measure brings the state’s car-seat laws, created in 1978, up to date with the recommendations of physicians and auto manufacturers.

Current law requires rear-facing car seats until age 1; forward-facing car seats until age 3; and booster seats until age 8.

The bill would change those rules to require rear-facing seats until age 2; forward-facing car seats until age 5; and booster seats until children turn 12 or reach a height of 4-foot-9.

The Senate passed the bill on a 32-0 vote Monday while the House vote was 68-19. It now heads to Republican Gov. Bill Haslam, and Haslam’s aides have not said whether the governor will sign the legislation.
