Child Restraints Older Children Q: What is the proper way to wear safety belts? A: If possible, an older child should wear a lap-shoulder belt and get the additional restraint a shoulder belt can provide. The shoulder belt should not cross the face or neck. The lap belt should fit snugly below the hips, just touching the top of the thighs. It should never be worn over the abdomen, which could cause severe or even fatal internal injuries in a crash. In a crash, children who are not buckled up can strike other people who are buckled up, or can be thrown out of the vehicle. Older children need to use safety belts properly. Older children who have outgrown booster seats should wear the vehicle's safety belts. If you have a choice, a child should sit next to a window so that the child can wear a lap-shoulder belt and get the additional restraint a shoulder belt can provide. 1-31
