Bus operators will often find it economical to convert retired buses to use as permanent training buses for driver training, rather than taking a regular service bus out of use. Some large operators also converted retired buses into tow bus vehicles, to act as tow trucks.
Explain to an 8 year old child that is not yet 49 tall that the safety equipment built into the vehicle is for adults  not children, and a child needs to continue to use the proper equipment (booster seat) so that the adult equipment will fit, and be able to protect, their bodies in the event of a crash.
Booster seats lift a child up to help adult seat belts fit children properly. Children must start riding in a booster upon outgrowing a forward-facing harness restraint (typically after turning age 4 and 40â60 pounds). It is safest for children to remain in a booster until they are 4 feet 9 inches tall, or at least age 8. Learn more about Minnesota's child passenger safety law, which requires a child who is both under age 8 and shorter than 4 feet 9 inches to be fastened in a child safety seat or booster.
