The bus with a driver and 11 passengers was returning from a conference in Chattanooga when the accident occurred Saturday along Interstate 840 south of Nashville.
According to the Tennessee Highway Patrol, the driver lost control and the bus struck a median and flipped on its side.
The children were from Bolivar’s Parrans Chapel Baptist Church, which had borrowed the bus from a sister church. Parrans Chapel says in a statement the children were released after being evaluated.
The driver was not injured. The accident remains under investigation.
