What is the age requirement for using child seats in vehicles?

The age requirement for using child seats in vehicles is typically set to ensure that children are safely and appropriately restrained while traveling. The correct choice indicates that children aged 5 and under must use child seats. This regulation is based on safety guidelines established to protect younger children whose bodies may not be adequately protected by standard seat belts due to their size and developmental factors.

Research has shown that correctly using a child safety seat can significantly reduce the risk of injury or death in the event of a car accident. As children grow and develop, the criteria for transitioning to different types of restraint systems — from rear-facing car seats to forward-facing and eventually to booster seats — depend on age, weight, and height. Ensuring that children up to the age of 5 are secured in appropriate seats helps safeguard their well-being during travel, which is the essence of this regulation.
