At what height do children no longer need to use a booster seat?

The correct answer indicates that children no longer need to use a booster seat once they reach a height of 4 feet 9 inches. At this height, children are generally tall enough for the vehicle's seat belt to fit properly across their bodies. Proper fit means that the lap belt sits low across the upper thighs and the shoulder belt crosses the chest and shoulder, providing the necessary restraint in case of a crash.

This height guideline is designed to ensure that safety features in vehicles can function effectively for children who have outgrown their booster seats, promoting their safety while traveling in a car. Understanding the correct usage of booster seats and when to transition out of them is crucial to child passenger safety.

Height limits for booster seat use vary, and in Texas, the law recognizes 4 feet 9 inches as the minimum height for transitioning away from booster seats, as it correlates with adequate seat belt fit for safety and effectiveness.
