{CAUTION:
Never do this.
Here two children are wearing the same belt.
The belt can not properly spread the impact
forces. In a crash, the two children can be
crushed together and seriously injured. A belt
must be used by only one person at a time.
Q:What if a child is wearing a lap-shoulder belt,
but the child is so small that the shoulder belt
is very close to the child’s face or neck?
A:If the child is sitting in a seat next to a window,
move the child toward the center of the vehicle.
If the child is sitting in the center rear seat
passenger position, move the child toward the
safety belt buckle. In either case, be sure that the
shoulder belt still is on the child’s shoulder, so
that in a crash the child’s upper body would have
the restraint that belts provide.
If the child is sitting in a rear seat outside position,
seeRear Safety Belt Comfort Guides for Children
and Small Adults on page 1-25.

{CAUTION:
The body structure of a young child is quite
unlike that of an adult or older child, for whom
the safety belts are designed. 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. 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. Young
children always should be secured in
appropriate child restraints.
Child Restraint Systems
An infant car bed (A), a special bed made for use in a
motor vehicle, is an infant restraint system designed
to restrain or position a child on a continuous at
surface. Make sure that the infant’s head rests toward
the center of the vehicle.
