Always use a booster seat with what?

Always use a booster seat with children who have outgrown their forward-facing car seats but are still too small to fit safely in a regular seat belt. Typically, this applies to children aged 4 to 8 years old, depending on their height and weight. The booster seat helps position the seat belt correctly across the child's chest and lap, ensuring optimal safety during travel. Always check local laws and guidelines for specific requirements regarding booster seat use.
