UNDATED (WSAU) Amid near zero-viability fog, a school bus was involved in a crash in Shawano County. It happened just after 7am on Highway 29 just east of Kroenke Creek Road in the Town of Herman when a van rear-ended the stopped school bus, which was picking up a passenger.

Sheriff's Department Deputy Thomas G. Tuma says, "There were eight student passengers and the driver on board at the time of the crash.  The bus driver complained of injuries at the scene and was transported to Shawano Medical Center for non-life threatening injuries.  None of the student passengers were injured in the crash."  Tuma also says the van driver was not seriously hurt and refused transport to the hospital.

The crash remains under investigation by the Shawano County Sheriff's Department. Tuma could not comment on possible causes or contributing factors to the accident because of the ongoing investigation.

Assistance at the scene was provided by Wisconsin State Patrol, Gresham Fire Department, Gresham Emergency Medical Services, and the Shawano Ambulance Service.

For many school districts in the state, today is the first day of school. A large part of Central Wisconsin has been blanketed with dense fog leaving visibility below a quarter-mile.
