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

For children aged 4-8 years, the requirement for a booster seat is based on safety guidelines that ensure the proper fit of seat belts for children. Booster seats are designed to elevate a child to ensure that the vehicle's seatbelt is positioned correctly across the stronger parts of their body—a critical factor in providing maximum protection in the event of a crash.

Up until the age of 8, children may not be tall enough for the seatbelt alone to fit properly. A booster seat provides the necessary height to achieve this fit, helping to prevent injury by making sure the lap belt sits across the child's hips and the shoulder belt crosses the middle of their chest. This specific age range often requires children to transition from a forward-facing child seat to a booster seat to align with their growth and physical development.

While rear-facing car seats are suitable for younger children, typically from birth until around 2 years of age, they are not appropriate for this specific age range of 4-8 years. Forward-facing child seats are useful as children grow older, but booster seats are mandatory for this age group to ensure safety and compliance with regulations. A regular seatbelt alone is not adequate without a booster seat to ensure the proper fitting and positioning.
