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. 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 bestable to take belt restraining forces. The safety belt locks if there's a sudden stop or a crash.
