According to the new complaint, in September, Brian Ruoss of Gilbertsville was driving to work at 6 a.m. in the left lane on Route 422 near the Sanatoga interchange when the driver of a silver Buick Lucerne came up behind him and flashed his lights. The Buick driver then passed Ruoss and cut in front of him. Ruoss read the tag number to his passenger, who wrote it down.
