A single vehicle accident last night in Cumberland County resulted in two injuries. Deputies say a vehicle driven by 22-year-old Tristan E. Hassler of Crossville was traveling north on the 300 block of Pomona Road when he tried to negotiate a curve, went off the road and hit a tree head-on. Officers say the road was slick because of snow and ice. Hassler and a passenger in his vehicle, 23-year-old Stover K. Dwiggins of Crossville, were both transported to Cookeville Regional Hospital for treatment of injuries.
