What to look for in a safe seatbelt fit in a highback or backless booster seat: always read and follow your booster seat and vehicle owner’s manuals! Look for the lap belt to be low on the hips, touching the tops of the thighs, and the shoulder belt to be centered on their shoulder and making contact with their collarbone. #cpst #childpassengersafetytech #childpassengersafetytechnician #childpassengersafety #childpassengersafetytok #boosterseat #boosterseatsafety #boostersareforbigkids #seatbelt
