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:
Move the child toward the center of the vehicle, but
be sure that the shoulder beit still is on the chiid'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,
see Rear Safety Belt Comfort Guides for Children
and Small Adults on page 1-26. If the child is
so small that the shoulder belt is still very close to
the child's face or neck, you might want to place
the child in the center seat position, the one
that has only a lap belt.
Never do this.
Here two children are wearing the same belt.
The belt can't 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.
