Booster Seats:

Many parents are surprised to learn that safety belts generally do NOT fit children until they are between 8 and 12 years of age. Booster seats, used after children outgrow car seats with harnesses, are needed until that time.

Question: How can you know if your child (or the child you transport) is big enough to use the safety belt?

Answer: Use the Safety Belt Fit Test on every child under 13 you transport. Remember too, that all children under age 13 should ride properly restrained in a back seat.

Car seats and booster seats are designed to protect children and make them comfortable at the same time. There's nothing comfortable about a too-big safety belt cutting into a child's stomach or pressing against his face. Plus, kids who ride on booster seats can easily see many things they would otherwise miss.
