Twelve children were on board this bus when it landed in a ditch. What went wrong?

The accident happened this morning on Thunder City Road, south of Cascade according to KTVB.

For reasons unknown at this time, the driver drifted off to the side and slid into a ditch.

The kids on board ranged in age from elementary school to junior high kids and luckily the injuries appear to be pretty minor. Students suffered scratches, scrapes, and bruises.

Luckily they say the school bus was driving slow enough that it didn't completely roll and the injuries were not worse. It's always especially scary when children are involved.
