The main idea is knowing when a booster is no longer needed by checking the belt fit. Use a booster until the seat belt fits properly on the child without the booster. A proper fit means the lap belt lies low and snug across the hips and thighs, not the stomach, and the shoulder belt crosses the chest and shoulder, not the neck or face. When the belt sits correctly like this, the child is protected by the vehicle’s belt alone. Keeping a booster after the belt fits can lead to poor belt placement and reduced protection. Boosters are for older kids who still need help getting the belt to fit right, not for infants. Other statements suggesting boosters are optional after a certain age, or that the seat belt should never be used with a booster, don’t reflect how the belt should position and protect the body.
