At what ages are booster seats mandatory?

Answer: B — Ages 4-8

Booster seats are mandated for children ages 4 to 8 because they provide the necessary elevation for a child to safely use the adult seat belt. This age range is critical as children are typically transitioning out of forward-facing car seats but are not yet tall enough to properly fit in a seat belt designed for adults. The use of booster seats helps to ensure that the seat belt fits correctly across the child's shoulder and lap, thereby reducing the risk of injury in the event of a crash. While other age ranges include important safety considerations, the specific focus on ages 4 to 8 aligns with guidelines set by safety organizations that aim to protect children during a key developmental phase related to car safety. It is essential to follow these recommendations to enhance overall safety for young passengers.
