The officer says the girl was operating the Dodge Durango station wagon while her 30-year-old mother was sitting in the passenger seat, laughing. She reportedly told the officer she was teaching the child to drive.

The child's aunt showed up at the scene and police say she asked the young girl, “If her mother made her drive the car?”

Then police say the aunt asked her niece, "Was your mom smoking that stinky stuff again?" Te girl replied "yes," say police.

Police have charged the woman with endangering the welfare of a child, corruption of a minor, recklessly endangering another person, and permitting violation of title.

Her name is being withheld to protect the identity of her child.
