40 to 100 Pounds

  • Use a booster seat correctly in a back seat every time your child rides in a car.
  • Older kids get weighed and measured less often than babies, so check your child's growth a few times a year. Use a booster seat until your child weighs between 80 and 100 pounds, is about 4 feet, 9 inches tall and can pass the Safety Belt Fit Test. For most children, that will be between ages 8 and 12.
  • Tell all drivers who transport your child that booster seat use is a must when your child is in their vehicle.
  • A booster seat uses no harness. It uses the vehicle's lap and shoulder belts only. Be sure the safety belt is properly buckled.
  • Booster seats are not installed tightly. They sit on the vehicle seat; the child buckles the lap and shoulder belt and wears the safety belt like you do. Never use only the lap belt.
  • Use the vehicle's lap and shoulder belts on every booster seat. Never place the shoulder belt under the child's arm or behind the child's back.
  • Be sure all occupants wear safety belts correctly every time. Children learn from adult role models.
