A Head on accident occurred yesterday at approximately 3:56 pm on Lupe Road near the intersection of Lupe and Ridge Road in Pine Grove. Apparently a driver, while entering a sweeping curve, crossed over the center line and hit the other vehicle head on. The impact left the two vehicles blocking both lanes of traffic and traffic was backed up for about a half an hour while emergency crews cleared the roadway. American Legion ambulance responders attended to the injured occupants of the vehicles.  Both drivers had reportedly major injuries, one of which included severe facial trauma. The drivers were transported by American Legion ambulance to receive medical care. The accident is under investigation by the CHP.
