Children aged 4 to 8 years are required to use which of the following?

For children aged 4 to 8 years, the appropriate choice is the booster seat. Booster seats are specifically designed to elevate a child so that the vehicle's seat belt fits properly over their body. At this age range, many children have outgrown their forward-facing child seat but are not yet large enough for the standard seat belt to secure them safely. The booster seat helps ensure that the lap and shoulder belts are positioned correctly—across the upper thighs and over the shoulder—reducing the risk of injury in the event of a crash.

In contrast, rear-facing seats are typically used for infants and toddlers under the age of 4 to provide maximum protection for their developing bodies. Standard seat belts, while crucial for older children and adults, do not provide adequate restraint for younger children whose bodies are still growing, as they are designed for adult proportions. Forward-facing child seats are suited for children who have outgrown rear-facing seats, typically ranging from ages 2 to 4, but once a child reaches around age 4 and has met specific height and weight requirements, they can transition to a booster seat for safety.
