The Oklahoma Highway Patrol is reporting that a 22-year old Ardmore woman was injured in a collision with a semi truck earlier Friday on State Highway 53 east of Graham, in Carter County.

The woman was transported to Denton Medical Center in Denton, Texas, where she was admitted in serious condition with a head injury.

According to trooper report, the woman failed to stop at a stop sign before her 2003 Chevrolet Trailblazer was stuck on the passenger side by an oncoming 2001 Freightliner.
