A new effort is being launched to keep small children safe in cars. A proposed law would force children younger than 4, weighing 40 pounds or less, to be in child passenger restraint sytem. Children four to eight years old and weighing 40 to 80 pounds would have to be in booster seats. Highway Patrol Superintendent Roger Stottlemyre says the seats will make seatbelts fit properly. Those who don’t have the seats installed face $25 penalties. The proposed law would force rental car companies to inform customers of the requirement. It would also require rental agencies to provide appropriate child seats for rental. The proposal didn’t make it last year. It’s waiting to be sent to the Senate for debate.
