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 reaches a height of 4 feet 9 inches. That's nearly 1.5 meters.
  • Your child sits against the back of the seat with their knees bent comfortably at the edge of the seat.
  • The lap belt lies low across your child's upper thighs — not the stomach. The shoulder belt rests on the middle of your child's chest and shoulder — not on the neck or face.

Keep in mind that the back seat is the safest place for children younger than age 13.

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