L
The lap part of the belt should'be worn low and snug on
the hips, just touching the thighs. In a
crash, this applies
force to the s h n g pelvic bones. And you'd be less
likely to slide under
the lap belt. If you slid under it, the
belt would apply force at your abdomen. This could
cause. serious or even fatal injuries. The shoulder belt
should go over the shoulder
and across the chest. Thlese
parts of the body are best able to take belt restraining
forces.
The safety belt locks if there's
a
sudden stop
or
crash.
