3-40 Seats and Restraints
restraint should take into
consideration not only the child's
weight, height, and age but also
whether or not the restraint will
be compatible with the motor
vehicle in which it will be used.
For most basic types of child
restraints, there are many
different models available. When
purchasing a child restraint, be
sure it is designed to be used in
a motor vehicle. If it is, the
restraint will have a label saying
that it meets federal motor
vehicle safety standards.
The restraint manufacturer
instructions that come with the
restraint state the weight and
height limitations for a particular
child restraint. In addition, there
are many kinds of restraints
available for children with
special needs.
Warning
To reduce the risk of neck and
head injury during a crash, infants
need complete support. In a
crash, if an infant is in a
rear-facing child restraint, the
crash forces can be distributed
across the strongest part of an
infant's body, the back and
shoulders. Infants should always
be secured in rear-facing child
restraints.
Warning
A young child's hip bones are still
so small that the vehicle's regular
safety belt may not remain low on
the hip bones, as it should.
Instead, it may settle up around
the child's abdomen.

Warning (Continued)
In a crash, the belt would apply
force on a body area that is
unprotected by any bony
structure. This alone could cause
serious or fatal injuries. To reduce
the risk of serious or fatal injuries
during a crash, young children
should always be secured in
appropriate child restraints.
