At what height can a child typically transition from a booster seat to a regular seatbelt?

Transitioning from a booster seat to a regular seatbelt is primarily based on a child's height and development rather than their age alone. The guideline indicating that a child can typically transition to a regular seatbelt at a height of 4 feet 9 inches is based on ensuring that the seatbelt fits properly. When a child reaches this height, the seatbelt can be positioned correctly across the child's lap and shoulder. This pertinent adjustment ensures maximum safety during a car ride.

At 4 feet 9 inches, many children can safely use the vehicle's seatbelt without the added protection of a booster seat, as they are generally able to sit properly against the vehicle's seat. The correct fit is crucial for effective restraint in the event of a crash, reducing the risk of injury.
