The crash took place Nov. 14 in Nashville, where the actress films her ABC show, "Nashville," TMZ reported.
Panettiere ran a red light with her BMW, while at the same time the other driver -- in a Geo Prism -- illegally turned into the actress' lane, the accident report said.
Panettiere was driving in the right lane through an intersection when the Prism driver made a left turn into her lane instead of the left lane, the report said. A witness told police the actress had run a red light.
No one was seriously injured in the crash, TMZ reported.
