Blood could be seen on the car's windscreen.
The 49-year-old woman was found by police about 12 hours later. Police were notified of the crash at 8.30am yesterday. Arrowtown community constable Senior Constable Beth Fookes said it occurred at 1.30am yesterday in Manse Rd.
Police said the car was registered to a woman living in Manse Rd. Yesterday morning, police reported they had yet to find her as she had not turned up at her home.
Acting Sergeant Tracy Haggart could not confirm where the woman was found but said she was ''safe and well''.
She was unsure whether the woman had required medical attention.
Snr Const Fookes said the car had veered off the road and hit ''a very solid retaining wall'' before ending up on its roof and blocking three-quarters of the road.
Inquiries are continuing.
