The booster seat would raise the child so that a vehicle's seat belt system better fits the child.
According to the California Highway Patrol, a child who is 5 years old but weighs 63 pounds would not have to be placed in a specialized seat.
In addition, a 6-year-old child weighing under 60 pounds would not have to be placed in a specialized seat.
Highway Patrol officials have said the new law will replace the state's age 4 and 40 pounds law, which states children age 4 or younger have to be in a safety seat or booster. That law also states children regardless of age who weigh under 40 pounds have to be in safety seats or boosters.
Highway Patrol Officer Jason Burke said this morning the new law is designed to keep as many children safe as possible.
"The longer children are in the safety seats, the safer they are," Burke said.
He said there are other exceptions to the new law. He said the law takes into consideration that older vehicles do not have both lap and shoulder belts.
Burke said booster seats are only required in vehicles that have both shoulder and lap belts. Booster seats allow the seat belts to fit across the part of a child's body where he or she has strong bones.
Without a booster, a shoulder belt can cross a child's face, which does nothing to protect the upper body.
Burke said booster seats will not work with vehicles that only have lap belts. For that reason, a child would not have to be placed on a booster seat in a vehicle that only has lap belts.
