They say she is Judy Gail Siegel, 57, of Chapel Hill.
Investigators say they believe Siegel was driving a Toyota in the far right eastbound lane of I-40 when she struck the side/tire of a tractor-trailer in the next lane.
The impact caused the Toyota to go off the right side of the highway, hit a guardrail and stop on the shoulder.
Investigators believe Siegel then got out of her vehicle and walked into the middle of I-40 East where she was struck by multiple vehicles. The first vehicle that hit her did not remain at the scene.
Police are looking for that vehicle.
