 And your kids are probably riding in car seats that are being used incorrectly. In fact, three out of four kids are not as safe as they should be. But the latch system is in most cars and makes it easier to get it right. Just attach the top tether and the lower anchors. The ones down near the old sandwich and the melted down crayons. Anchor, tether, latch. The next generation of child safety. A message from the U.S. Department of Transportation and the Ad Council.
