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.
The Bottom Line. Before moving to a booster seat, your child should be: 1  At least 5 years old. 2  Meet the weight and height minimums for the booster seat youâre considering. 3  Responsible enough to sit properly 100% of the time, even while asleep.hat means the decision to move from harness to booster is rooted in the childâs maturity. The ability to sit correctly for the entire ride, 100% of the time, happens somewhere past age 5 for most kids, and not until 6 or 7 for a many others.
