Laws aside, kids aren't ready to make the switch from a booster seat to seat belts until they're at least 4 feet 9 inches tall and can pass the five-step test below â typically between ages 8 and 10.
Usually a child can be moved to a booster when they are too big for a harnessed carseat, and once they are able to sit properly in a seatbelt. A child should be in some type of booster seat until the adult seat belt fits correctly, generally around 8-12 years old and 4'9 tall (Also see Question 9 below). Q8: My child is over 40 pounds or too tall for his carseat, but isn't mature enough to sit in a seatbelt with a booster.
