Lewiston firefighters and United Ambulance personnel assist an injured driver after the dump truck he was driving tipped over  Thursday morning at a work site on Lexington Street in Lewiston. Police said the truck was fully loaded when it tipped. Because it happened on private property, the Occupational Safety and Health Administration was called to investigate. The driver was taken to Central Maine Medical Center as a precaution, police said. His name was not immediately available. Daryn Slover/Sun Journal
