Step-by-step explanation:
Under the Graduated Driver Licensing (GDL) rule, it is mandatory for every passenger in the car to wear seat belts.

The purpose of the GDL is to provide a controlled environment for new drivers to gain experience.

Society has a vested interest in reducing road traffic incidents and the related healthcare burdens that arise from individuals being injured while not wearing a seat belt.
