The US National Highway Traffic Safety Administration and the American Academy of Pediatrics recommend that:
- All children 12 and under should ride in the back seat.
- Children over 40 lbs. up to 80 lbs. should sit in a belt-positioning booster seat with both lap and shoulder belt.
- The booster seat should face forward.
- Snug belts: The lap belt should fit low and tight across the lap/upper thigh area of the child and the shoulder belt should fit snug crossing the chest and shoulder (to avoid abdominal injuries).
