At what age can a child stop using a booster seat?

The appropriate age for a child to stop using a booster seat is 8 years old. By this age, most children have grown sufficiently in height and weight to be safely secured with a seatbelt alone. Booster seats help elevate a child so that the seatbelt fits correctly across their body—specifically, the lap belt should lie snugly across the upper thighs, and the shoulder belt should cross the chest and shoulder.

The law and safety guidelines suggest that children should remain in a booster seat until they are at least 8 years old or until they reach the maximum weight or height limit of their booster seat. It is essential to prioritize the child's safety and ensure that they are adequately restrained in accordance with both state laws and the recommendations set forth by safety experts.

Although some may believe younger ages could be sufficient, children develop at different rates, and the key factor is ensuring a proper fit of the seatbelt, not merely the age.
