The 19-year-old woman told Dallas police she met the man at a concert and he offered to give her a ride. She says she was shoved from the vehicle when she rejected his sexual advances.
The video also shows another woman running to the victim's aid, getting her to roll to the side of the exit ramp and out of the way of traffic.
Authorities say the victim was treated for severe road rash.
The video was released Wednesday. The victim has asked that her name not be used.
