It happened around 7:30 a.m. after the drivers involved in a rear-end collision stopped on the side of the highway.
A witness told ABC11 that a woman in one of the vehicles was walking back to her car - with her back to traffic - when a car hit her.
"She hit her and knocked her in the air and out of her shoes," said the witness.
The witness said the car that hit the woman initially pulled over, but didn't stay long.
"As I was walking back to my car, they left," she said.
Pictures from the scene showed emergency workers treating the woman, who was conscious and speaking with them as she was loaded into an ambulance.
Police later identified her as 26-year-old Zaida Juarez of Durham and said her injuries did not appear to be life threatening.
Durham police released video of the incident from a police officer's dash mounted camera Friday afternoon. In it, you can see the white car swerve to avoid slowing traffic and steer into the shoulder. You do not see the woman get hit.
