What is the ruling on wearing a safety belt that defines body parts?

The driver and passengers must wear seatbelts to protect against accident injuries, and in compliance with the state's orders, which are to be obeyed in matters of good. The mention of it defining body parts is not a deterrent; it does not define the awrah of a man, and for a woman, it does not delineate her body precisely. She can also distance it slightly from her body.
