32-year-old Nicole Sanson was injured in a crash in Cass County on Wednesday in Silver Creek Township.
Authorities say she was driving south on M51 when an oncoming vehicle entered her lane. A red passenger vehicle was attempting to pass a semi on northbound M51.
Sanson swerved to the right shoulder of the road to avoid it, but then overcorrected as she turned back into the road. She was struck by the semi.
Sanson was not wearing her seatbelt and was transported to a Michigan hospital with injuries.
The red passenger vehicle left the scene of the accident.
