Which car safety device should be used for an 8-year-old child who is 4 feet tall?

• A. Front-facing car seat
• B. Infant car seat
• C. Booster seat
• D. Seat belt alone

Answer: (C)

The main idea is choosing a restraint that makes the seat belt fit correctly for the child's height. At four feet tall, an eight-year-old needs a booster seat because they’re too tall for an infant seat or a front-facing harness, but not tall enough yet for the seat belt to fit properly on its own. A booster raises the child so the lap belt lies low across the hips and the shoulder belt crosses the chest and shoulder, not the neck or face. This proper positioning reduces injury risk in a crash and helps the belt work as intended. Typically, kids stay in a booster until about 4'9" (57 inches) tall and around 8–12 years old, depending on belt fit and growth. The other options don’t position the belt correctly for a child of this size, whereas the booster provides the right height and belt placement.
