The decision point for transitioning your child out of a booster seat and into a seat belt usually comes when the child is between 8 to 12 years old: Keep your children in booster seats until they outgrow the size limits of the booster seats or are big enough to fit properly in seat belts.
For a child to properly fit a seat belt, your child must:
Always check belt fit on the child in every vehicle. A booster seat may be needed in some vehicles and not in others. If the seat belt does not fit properly the child should continue to use a booster seat.
The transition to a seat belt gives you another opportunity to teach your child about safety. The first message is simple: Even though your child is now the right size to fit a seat belt, the safest place to ride in the car is still in the back seat -- buckled up.
As a parent, you influence your kids by modeling safe driving practices, including buckling up every time you get in the car. Teach your family that safety is the responsibility of all passengers as well as the driver.
