According to federal car seat regulations, what age group should use a booster seat until they reach what height?

4'5"
4'9"
5'0"
5'5"

The correct answer is: 4'9"

The correct answer is based on federal car seat safety regulations, which state that children should use a booster seat until they reach a height of 4'9". This height requirement is established to ensure that the seat belt fits properly and effectively protects the child in the event of a car accident. A properly fitted seat belt must lie across the child's upper thighs, not their stomach, and the shoulder belt should cross the shoulder between the neck and arm to prevent injury during a crash. Using a booster seat until a child reaches 4'9" helps to maximize their safety by providing the necessary elevation so the adult seat belt can be used correctly. It is essential to follow these guidelines, as they are based on research into child passenger safety and the biomechanics of how seat belts work in restraining a child during a collision.
