Two semitrailers collided and hit another truck in Greene County Monday, sending two of the three drivers to the hospital. The accident was reported at the intersection of U.S. Highway 30 and S Avenue, near Grand Junction. Greene County Sheriff Jack Williams said a semi hauling hogs, driven by Travis Davis, 37, of Wayland, was southbound on S Avenue when it ran a stop sign at Highway 30. When it ran the stop sign, it struck the trailer of a westbound tanker that was filled with gasoline, which was being driven by Jeffrey Mercer, 43, of Osceola. There were about 8,000 gallons in the tanker.
