Q:
What is wrong with this?
A:
The lap belt is too loose. It will not give nearly
as much protection this way.

CAUTION:
{
You can be seriously hurt if your lap belt
is too loose. In a crash, you could slide
under the lap belt and apply force at your
abdomen. This could cause serious or
even fatal injuries. The lap belt should
be worn low and snug on the hips, just
touching the thighs.
