What is the purpose of a child restraint device for children aged eight to 12?

The purpose of a child restraint device for children aged eight to 12 is primarily to ensure safety in case of a crash. These devices are designed to protect younger passengers by properly securing them in the vehicle. Child restraints help to minimize the risk of injury during an accident by correctly positioning the seatbelt across the child's body, as well as providing the appropriate support and protection needed for their size and weight.

Utilizing a child restraint device significantly reduces the chances of serious harm by absorbing some impact forces and preventing ejection from the vehicle. The safety benefits are crucial, as properly used child restraint systems are proven to decrease the risk of injury and death in crashes for younger passengers. Other options, such as comfort and distraction avoidance, are secondary considerations but do not capture the fundamental safety purpose of these devices.
