I can do this! - 5-8 years old
When traveling in cars, children should to be seated in the back seat and secured in a restraint appropriate for their age and height to minimise injury in the case of a car crash.
Children up until at least the age of 4 years must be secured in a child restraint with inbuilt harness until they no longer fit, and then they should use a booster seat until a good adult seat belt fit can be achieved. This is usually when they are about 145cm tall and the adult seat belt fits low across the hip bones and the shoulder strap passes the middle of the shoulder, not across the neck. The lap belt should not ride up over the soft abdomen.
When using an adult seat belt either alone or with a booster seat, make sure that the shoulder strap is not placed under the child’s arm or behind their back.
