This is the third accident involving a Hamilton County Schools bus this week.
Around 3:30 p.m. on Thursday, a bus was involved in a multi-vehicle crash also on Highway 153 with no students onboard.
On Wednesday, two buses were involved in a crash after one bus hit the other at the intersection of Hunter Road and Barkley Creek Drive.
The accident occurred around 6:30 a.m. while students were being transported to school. About 48 students from Hunter Middle School and Central High School were involved and some reported injuries later in the day.
