How old do you have to be not to use a booster seat in Georgia?

In Georgia, children can stop using a booster seat when they reach the age of 8. However, they must also weigh at least 40 pounds and be tall enough to properly fit in a regular seat belt, meaning the lap belt should fit snugly across the upper thighs, and the shoulder belt should cross the chest and shoulder. It's important to ensure that the vehicle's seat belt system fits the child properly for safety.
