An unidentified motorcyclist was taken to Oconee Medical Center on a stretcher and wearing a neck brace Monday when he was hit by a silver Buick LaSabre on W. N. 1st Street in Seneca. The motorcycle was traveling toward Seneca when the eastbound Buick, driven by Agnus Henderson of Clemson, attempted to turn left. Henderson was cited for failure to yield right of way. The unidentified male on the motorcycle was the only injury person in the incident.
