When are children required to use a booster seat?

Children are required to use a booster seat until they reach a height of 145 cm or the age of 9 years. This regulation is based on safety standards designed to ensure that seat belts fit properly, which is crucial for protecting children in the event of a collision. A properly fitting seat belt should lie snugly across the shoulder and chest, and the lap belt should sit low across the thighs.

Using a booster seat helps position the seatbelt correctly for younger children who may not yet be tall enough for standard seatbelts to fit them safely. This transition ensures they are adequately protected as they grow. It's important to monitor both height and age, as either can determine when a child is no longer required to use a booster seat. By adhering to these guidelines, caregivers can help ensure the safety of child passengers during travel.
