Car seat safety: Avoid 9 common mistakes

9. Switching to a seat belt too soon

Most kids can safely use an adult seat belt sometime between ages 8 and 12. Here's how you'll know that your child is ready:

  • Your child sits against the back of the seat with knees bent comfortably at the edge of the seat without slouching.
  • Your child can keep feet flat on the floor.
  • The lap belt lies low across your child's upper thighs. Avoid having the lap belt go across the belly. The shoulder belt rests on the middle of your child's chest and touches the center of the shoulder. Avoid letting the belt rest on the neck or face.
  • Your child can sit safely for the entire ride.

Keep in mind that the back seat is the safest place for children younger than age 13. This may be a law in your state.

It can be a good idea to take part in a local car seat clinic or inspection event. These can be helpful if you have questions about child passenger safety laws. People at these events also can help you install a car seat. You also can check with the National Highway Traffic Safety Administration for help finding a car seat inspection station.
