FOR THIS STAGE · Infants and children using child restraints US NHTSA guidance. Check local law and the specific seat and vehicle manuals. This guide cannot verify installation; use a qualified inspection service.
US public-health guidance · Read sources & review status ↓ A birthday can prompt questions about the next seat. Check the child, the seat, and the vehicle together before changing stages.
