School bus carrying 10 students rolls into ditch WINTERSET, Iowa (KCCI) — The Winterset Community School District said 10 elementary students and a bus driver were involved in a rollover crash Monday in Madison County. The crash occurred around 7:30 a.m. near the Hanson Prairie Preserve on 195th Trail and Nature Trail. The Madison County Sheriff’s Office did not confirm what caused the crash, but Winterset Superintendent Justin Gross said road conditions may have contributed to the rollover. “Our driver came across around the curve,” Gross said. “As you can see, the ground’s really soft due to the rain we had the last 24 hours and (the bus) kind of rolled into the ditch.”
