{CAUTION: Never do this. Here two children are wearing the same belt. The belt can't properly spread the impact forces. In a crash, the two children can be crushed together and seriously injured. A belt must be used by only one person at a time. Q: A: What if a child is wearing a lap-shoulder belt, but the child is so small that the shoulder belt is very close to the child's face or neck? If the child is sitting in a rear seat outside position, move the child toward the center of the vehicle. Also, see Rear Safety Belt Comfort Guides for Children and Small Adults on page 1-34. If the child is sitting in the center position, move the child toward the safety belt buckle. In either case, be sure that the shoulder belt still is on the child's shoulder, so that in a crash the child's upper body would have the restraint that belts provide. 1-39
