Sen. Scott Cyrway's bill would change the weight for requiring a car seat from 40 pounds and under to 55 pounds and under for children who are 2 years old or older.
Children younger than 2 years old must be in a rear-facing child restraint system.
Cyrway said his concern over safe child seats comes from his own experience in law enforcement.
"We want our children safe. And so, you know, I can't stress it enough because I've seen where children sometimes are not fastened properly or they're standing up," he said.
The bill would also increase fines for not using the correct child safety car seats. It also would repeal a current law that makes the failure to secure a child not admissible evidence in car accident court cases.
