flates in a crash. If this happens, serious or
fatal injury will result.
Infants and small children must be seated in
an appropriate infant or child restraint sys-
tem, which is properly secured with the ve-
hicle’s seat belt, fully in accordance with the
child seat manufacturer’s instructions.
A child’s risk of serious or fatal injuries is

are not properly secured in the vehicle and
the child is not properly secured in the child
restraint.
