The lap part
of
the belt should be worn low and snug
o n the hips, just
touching the thighs. In a crash, this applies force to the strong 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. These parts
of
the body are best able
to
take belt restraining forces.
The safety belt locks if there's a sudden stop or crash.
