(WEST UNITY) - Four students were injured Monday morning when a car hit the back of a Mill-Creek West Unity school bus. The Ohio Highway Patrol says the accident happened at 7:25am on U.S. 20-A near West Unity. They say 62-year-old bus driver Deborah Connolly of West Unity was stopped with the red flashing lights and stop sign activated to pick up a student. Troopers say an eastbound car driven by 61-year-old David Whitman of Montpelier failed to see the stopped school bus and tried to avoid a collision by going off the road. The car hit the right rear of the bus. Debris from Whitman's car struck and injured a student who was waiting to get on the bus. Three of the 20 students on board the bus claimed injury. All of the students were treated at the Mill Creek-West Unity School by the Williams County E.M.S.. None of them were transported. Whitman was cited for Assured Clear Distance Ahead and a stopped school bus violation. The Williams County Sheriffs Office, Williams County E.M.S. along with West Unity Police and West Unity/Brady Township firefighters assisted at the scene.
