Q:
What is the proper way to wear safety belts?
A:
An older child should wear a lap-shoulder belt and
get the additional restraint a shoulder belt can
provide. The shoulder belt should not cross the face
or neck. The lap belt should fit snugly below the hips,
just touching the top of the thighs. This applies belt
force to the child's pelvic bones in a crash. It should
never be worn over the abdomen, which could cause
severe or even fatal internal injuries in a crash.
Also see "Rear Safety Belt Comfort Guides" under
Lap-Shoulder Belt on page 1-25.
According to accident statistics, children and infants
are safer when properly restrained in a child restraint
system or infant restraint system secured in a rear
seating position.
In a crash, children who are not buckled up can strike
other people who are buckled up, or can be thrown
out of the vehicle. Older children need to use safety
belts properly.

CAUTION:
{
Never do this.
Never allow two children to wear the same safety
belt. The safety belt can not properly spread the
impact forces. In a crash, the two children can be
crushed together and seriously injured. A safety
belt must be used by only one person at a time.
