What should be ensured about the shoulder belt when it is worn?

The shoulder belt is a critical component of a vehicle's safety restraint system, designed to keep occupants secure in their seats during a collision. Ensuring that the shoulder belt is not too loose is vital for effective protection. A properly fitted shoulder belt should fit snugly across the chest and over the shoulder without excessive slack. This snug fit provides maximum restraint in the event of an accident, preventing the occupant from moving too far forward or out of their seat.

Wearing the shoulder belt correctly ensures that it effectively distributes crash forces across the stronger parts of the body, minimizing the risk of injury. When the belt is too loose, it may fail to provide the necessary protection, leading to a greater risk of injury during a collision.
