WARNING
You can be seriously hurt if the
shoulder belt is too loose. In a
crash, you would move forward
too much, which could increase
injury. The shoulder belt should fit
snugly against your body.
Q: What is wrong with this?
A: The lap belt is too loose.
It will not give nearly as
much protection this way.

just touching the thighs.
