A foul-mouthed bus driver in Arizona is facing charges after deliberately slamming on the brakes, sending an 11-year-old boy crashing into the windshield, video shows.

Surveillance footage from inside the Mesa Public Schools bus shows Jamie Danielle Tellez, 50, berating two students on Oct. 4 as they stand in the aisle after one of them apparently missed a basket while tossing out a piece of trash.

“You better get your s–t down there and pick that up right now,” Tellez says. “I’m gonna knock the s–t out of you.”

Tellez then slams on the brakes, causing one of the students, an 11-year-old, to violently crash into the windshield. The driver then grabs the youngster by his backpack and heaves him toward the back of the bus, video shows.

“What did I tell you?” Tellez screams. “See what happens when you’re standing in the f—king aisle?!”

The boy then claims it wasn’t his fault, further aggravating Tellez, according to the disturbing footage.

“No, yeah, it is your fault, because if you were behind the seat, then you wouldn’t be flying around the bus, would ya?”

Tellez then demands that one of the students pick up the trash, which he does, video shows.

“You are the biggest pain in the ass, do you know that?” Tellez tells the boy.

The boy who crashed into the windshield was later taken to a hospital with injuries to his head and body, according to court records obtained by the Arizona Republic.

Tellez, who has been charged with child abuse, reckless driving, endangerment and threatening or intimidation, has been placed on unpaid administrative leave and will be recommended for termination, district officials said in a statement.

“The behavior and actions of Jamie Tellez while driving a district bus were inexcusable,” the statement read. “As soon as we became aware of the incident, we contacted Mesa Police. The district also reached out to the families of the children on the bus to ensure their well-being.”

Attempts to reach Tellez — a driver for the district since September 2018 — were unsuccessful early Friday.
