Lilian Waldron, a 10-year-old from Green Bay, was left with severe bruising on her arm following the incident.
When the child reluctantly exited the bus he was attacked by another child, footage showed.
The accident occurred at around 7:30 a.m. in Fulton County.
One Tennessee trucker was on a mission to save "the leftovers" from harm's way.
The bus was from East Brook Middle School in Paramus, New Jersey.
Surveillance footage captured a California bus driver calling the girl a "baby" and shoving her into a seat several times.
All of those killed were under 10 years of age.
"Get your hands off me," the boy screamed as he was forcibly dragged off the bus upside down.
