Information is still scarce following a serious accident in Young County Thursday morning involving an Olney man.
Officials said at around 7:50 a.m. an SUV, driven by the Olney man, collided with a semi-truck on Highway 380 northwest of Graham.
The Department of Public Safety said the highway remained closed all morning until the investigation was completed and all vehicles removed.
A witness says the semi jackknifed and the cab appeared partially turned on its side.
Two people inside the semi were airlifted from the scene with non-life threatening injuries.
The driver of the SUV was also seriously injured.
