It’s often the difference between life and death.
During a crash, properly fastened safety belts distribute rapid deceleration over certain parts of the person’s body, such as the chest, hips and shoulders. The safety belt stretches slightly to slow your body down and to increase its stopping distance. There is a huge difference between an unbelted and belted person’s stopping distance.
Seat Belts are the best protection in a car accident
Use the Safety Belt Fit Test on every child under 13 years of age. Remember too, that all children under age 13 should ride properly restrained in a back seat.
Once the safety belts correctly fit children, both shoulder strap and belt should be correctly used.
