Q: What is wrong with this?
A: The belt is buckled in the wrong buckle.
WARNING:
You can be seriously injured if your belt is buckled
in the wrong place like this. In a crash, the belt
would go up over your abdomen. The belt forces
would be there, not on the pelvic bones. This
could cause serious internal injuries. Always
buckle your belt into the buckle nearest you.
