When the seat belt is not properly tightened, its loose straps cannot restrain the body correctly during braking or a collision. This significantly reduces its protective capacity and increases the risk that the occupant will suffer serious injuries by not being properly secured to the seat. That is why it is essential to always adjust the belt so that it is taut against the body.
