When is it safe to move child from his booster seat to an adult seat belt?
Your child should stay in a booster seat until the adult seat belt fits. This usually occurs when your child is about 4’9″ in height and is 8 to 12 years old. The seat belt fits properly when: • The shoulder belt lies across the chest, not the neck of face. • The lap belt is low and snug across the thighs, not across the stomach. • The child is tall enough to sit against the vehicle seat back with his legs bent at the knees and feet hanging down.
