Police were alerted by staff at the city centre club in Clermont-Ferrand in the southern Auvergne region who spotted the girl sitting alone in the car.
When police arrived at 4am they found the girl still sitting in the car which had been parked in the nightclub's car park.
The girl was taken to the local police station and later to her father.
When police went into the nightclub they found the girl's mother in high spirits on the dance floor.
"She was drunk and not happy that they had turned up. She took exception when she was read her rights and wouldn't explain herself," reported local newspaper La Montagne.
Family protection services have been notified of the incident.
