When children should use booster seats
Children need to use booster seats from the time they outgrow the
toddler seat until they are big enough for the vehicle seat and
lap/shoulder belt to fit properly. Generally this is when they reach a
height of at least 4 feet 9 inches (1.45 meters) tall (around age eight to
age twelve and between 40 lb (18 kg) and 80 lb (36 kg) or upward to
100 lb (45 kg) if recommended by your child restraint manufacturer).
Many state and provincial laws require that children use approved
booster seats until they reach age eight, a height of 4 feet 9 inches
(1.45 meters) tall, or 80 lb (36 kg).
Booster seats should be used until you can answer YES to ALL of these
questions when seated without a booster seat:
• Can the child sit all the way back
against the vehicle seat back with
knees bent comfortably at the
edge of the seat cushion?
• Can the child sit without
slouching?
• Does the lap belt rest low across the hips?
• Is the shoulder belt centered on the shoulder and chest?
• Can the child stay seated like this for the whole trip?
Types of booster seats
There are generally two types of belt-positioning booster seats: backless
and high back. Always use booster seats in conjunction with the vehicle
lap/shoulder belt.
• Backless booster seats
If your backless booster seat has a
removable shield, remove the
shield. If a vehicle seating position
has a low seat back or no head
restraint, a backless booster seat
may place your child’s head (as
measured at the tops of the ears)
above the top of the seat. In this
case, move the backless booster
to another seating position with a
higher seat back or head restraint and lap/shoulder belts, or consider
using a high back booster seat.
