Seat belts save lives.
If the driver of a vehicle is buckled up, studies show that children will also be buckled. When a driver is unbuckled the children won t be buckled either. Proper usage of the seat belts is a necessity. Shoulder straps should be across the collarbone and the lap belt needs to be low on the hips. Never allow a child to slip the shoulder belt behind the back of the seat, their own back or under their arm because this is very dangerous in a car accident.
