Police haven't released the name of the girl whose mother was reportedly still sleeping when the girl took the woman's car keys about 9 a.m. Sunday.
Police Sgt. Jerry Parker tells reporters the little girl is tall for her age, but adds: "How she knew how to operate a car, your guess is as good as mine."
Police say the girl hit two parked vehicles, pushing one of them into a third, before hitting a utility pole.
Police and the girl's father arrived to take her home after the accident.
Police are still investigating but haven't said if anyone will face charges.
