MOSINEE, WI (WSAU) -  Nobody was injured in a Mosinee school bus accident yesterday. Twelve students and the driver were in the bus when it tipped over on Cesewski Road during the morning pickup route at about 6:45 a.m. Marathon County Sheriff’s investigators say an oncoming vehicle approached the bus in the middle of the road and the bus driver moved over to avoid a collision.

The Burnett Transit bus was travelling about five miles per hour when it tipped and has very little damage. The bus driver took a drug and alcohol test afterwards and passed.

Officers don’t know who the driver of the oncoming vehicle was. That driver never stopped.
