Child Restraints
Older Children
Older children who have outgrown
booster seats should wear the
vehicle
’
s seat belts.
The manufacturer instructions that
come with the booster seat state the
weight and height limitations for that
booster. Use a booster seat with a
lap-shoulder belt until the child
passes the fit test below:
.
Sit all the way back on the seat.
Do the knees bend at the seat
edge? If yes, continue. If no,
return to the booster seat.
.
Buckle the lap-shoulder belt.
Does the shoulder belt rest on
the shoulder? If yes, continue.
If no, try using the rear seat belt
comfort guide, if available. See
“
Rear Seat Belt Comfort Guides
”
under
If a comfort guide is not
available, or if the shoulder belt
still does not rest on the
shoulder, then return to the
booster seat.
.
Does the lap belt fit low and
snug on the hips, touching the
thighs? If yes, continue. If no,
return to the booster seat.
.
Can proper seat belt fit be
maintained for the length of the
trip? If yes, continue. If no,
return to the booster seat.
If you have the choice, a child
should sit in a position with a
lap-shoulder belt and get the
additional restraint a shoulder
belt can provide.
