Police Lt. Andy Neiman said Sunday the 26-year-old actress stopped after the accident and looked at the other vehicle and determined there wasn't any damage. Police said Bynes drove away without giving her information, which is required by law.
Neiman said police will turn over the case over to the city attorney's office for review.
No one was injured and the damage to the other person's vehicle in the Aug. 4 incident was more than $800.
Bynes has pleaded not guilty to a driving under the influence charge after she was arrested in April for grazing a sheriff's patrol car.
