WORTH TWP — A 33-year-old Ohio man was injured Monday morning in a two-vehicle crash on Interstate 79 southbound in northern Butler County, authorities said.

The man, whose name was not immediately available, reportedly hit a tractor-trailer that was pulled off the side of the highway about 6:40 a.m. The driver of the rig had stopped after hitting a deer.

The Ohio man suffered a bleeding head injury, according to a 911 report, and his truck ended up in a wooded area. He was conscious when emergency responders reached him.

Slippery Rock EMS took him by ambulance to Allegheny General Hospital in Pittsburgh. Medics described his injuries as “moderate.”
