Authorities are looking for the driver of a red Freightliner tractor-trailer rig that was reported to have crossed the center line, forcing an on-coming tractor-trailer rig into the ditch.

Greg Peterson, one of the Peterson Farm Bros, reported that he was westbound on Kansas Highway 4 (K-4) near Holmes Road shortly after 3 p.m. Wednesday when the 2004 Freightliner he was driving was forced into the ditch because an oncoming red Freightliner hauling a cattle trailer crossed the center line, Saline County Undersheriff Brent Melander said Thursday.

Peterson’s rig overturned, spilling its load of milo into the ditch, but Peterson was not injured, Melander said. The red Freightliner did not stop and continued east on K-4, he added.

A couple who witnessed the incident and who had no connection to Peterson told deputies that the red Freightliner had been traveling at a high rate of speed and had crossed the center line multiple times, Melander said. The red Freightliner also had a big black dog in the cab, he said.

Persons with information as to the identity of the driver of the red Freightliner are asked to contact the Saline County Sheriff’s Office.
