From OP: A very scary ordeal for this 18 year old driver last Friday night on the Muskogee Turnpike. She failed to yield to a semi while merging onto the highway, hit it and went spinning out of control. She is ok. The people in the red car that she hit are ok as well. This is her own dash cam video. Her dad gave it to the Highway Patrol for training purposes.Credit: Oklahoma Highway Patrol
