Once children outgrow their booster seat (usually at 10 â 12 years old) they can use the adult lap/shoulder safety belt if it fits them properly. Lap portion low over the hips/tops of thighs and shoulder belt crosses the center of the shoulder and center of the chest.
Q-What about children who outgrow their safety seats before age four?* A-Most 2-year-olds and many 3-year-olds are too immature to sit still in a booster with a lap and shoulder belt, which allows them to lean forward or sideways.
