A tractor-trailer driver was lucky to walk away uninjured following an accident on I-75 in Loudon County last Friday morning. Troopers say 60-year-old Juan Francisco Osores of Miami was traveling south near the 84 mile-marker. He attempted negotiating a downhill curve and lost control, struck the guard-rail, and over-turned. The vehicle rolled down a steep embankment and came to a rest on its side. Osores was restrained at the time of the crash.
