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 strong pelvic bones.

The shoulder belt should go parts of the over the shoulder and across the chest. These body are best able to take belt restraining forces. 5 . To make the lap part tight, pull down on the buckle end of the belt as you pull up on the shoulder belt. The safety belt locks if there's a sudden stop or crash, or if you pull the belt very quickly out of the retractor.
