A school bus driver charged with drunken driving told a police officer she was drunk but "not a bad girl," according to a video of the sobriety test.

Jennifer J. Reddy, 44, was charged with drunken driving and leaving the scene of an accident after she allegedly sideswiped a car Friday afternoon.

She drove the students back to school after they pleaded with her to return. Reddy was released from jail after posting a $1,000 bond.

The Knox County Sheriff's Department released video from the sobriety test on Tuesday.

Reddy told officer Christopher Wallace she drank vodka at home and had a last drink at 2 p.m.

Reddy swayed when the officer asked her to stand on one foot. "I'm drunk. I can't," she told the officer on the video.

Later she said, "I'm not a bad girl, I promise."

Reddy had already taken home a bus load of students from Farragut Primary School when she went to pick up students from the high school and middle school.

Reddy has been a bus driver since 2004, Knox County Schools spokesman Russ Oaks said.

Reddy declined to comment Monday. Her attorney, Don Bosch, said he couldn't comment much until his investigation was complete.

"This is a good family going through a difficult time," Bosch said.
