For children aged 4-8 years, which type of seat must they use?

For children aged 4-8 years, the appropriate type of seat is a booster seat. Booster seats are designed to elevate a child so that the vehicle's seatbelt fits properly over the child's shoulder and lap. This age group typically has outgrown a forward-facing child seat but are not yet large enough to safely use only a seatbelt.

Using a booster seat provides the necessary support for the correct seatbelt positioning, significantly reducing the risk of injury during a vehicle accident. It's crucial to ensure that children remain in this type of seat until they are tall enough (usually around 57 inches) to use the regular seatbelt safely without a booster. This is an important step in child passenger safety that helps ensure that the seatbelt fits correctly across the strong parts of a child's body.
