Are your older children and teens wearing their seat belts correctly? In this video, you’ll see how to ensure they are buckled up safely. Make sure your child does not tuck the shoulder belt under her arm or behind her back. This leaves the upper body unprotected and adds extra slack into the seat belt system, putting your child at risk of severe injury in a crash or with sudden braking. In addition, never allow anyone to “share” seat belts. All passengers must have their own car seats or seat belts.
