No students were injured in a two vehicle crash involving a school bus on a slippery, snow covered road in Dodge County. The crash happened shortly before 7:30am Thursday on Jefferson Road in the Town of Rubicon. There were no injuries to any students or the driver of the school bus and only minor injuries to the operator of the second vehicle. Investigators say the driver of a van was unable to stop on the snow-covered highway colliding with the back of the bus that had stopped to pick up students. Parents of the children were contacted and the children were released from the scene or transported to school by the bus service after the contact with parents.
