As the bus carrying seventh-graders headed Monday morning to Woodland Hills Junior/Senior High School in Churchill, alarmed students began calling their parents because the driver appeared to be falling asleep while the bus was moving.
After one student on Bus 440 called 911, a dispatcher notified the school resource officer.
When the bus pulled up, the officer intercepted driver Sharon Rox, who had glassy, bloodshot eyes and an unsteady gait, according to a police affidavit.
Ms. Rox, 37, of Duquesne, had trouble keeping her eyes open and spoke slowly, the officer wrote. She denied using any drugs or drinking any alcohol, and a portable breath test was negative.
But after Ms. Rox failed several field sobriety tests, the officer charged her by summons with endangering the welfare of children, recklessly endangering another person and two counts of driving under the influence.
Ms. Rox could not be reached for comment. No one could be reached from the Woodland Hills School District or school bus company.
Court records show that Ms. Rox was charged in 2005 with food stamp fraud. Ms. Rox was granted an accelerated rehabilitative disposition, but the records show that last month she was awaiting an ARD violation hearing.
