Police say the 17-year-old was standing in a parking space Friday to save it for someone.
Police say the teen and 41-year-old Angela Cornett argued before Cornett hit the girl with her car. Authorities say the incident was recorded on surveillance cameras.
Cornett told the Daily Tribune of Cartersville that she never hit the teen and said the girl leaned against her car.
The teen had a scuff mark to her knee but did not suffer any serious injuries, police said.
