Southern District Command Centre deployment co-ordinator Acting Senior Sergeant Ben Butterfield said the vehicle was travelling downhill about noon on Saturday when it was believed to have hit ice.
The vehicle tipped on to its side before coming to rest in a roadside ditch.
A St John Ambulance spokeswoman said the driver was taken to Dunedin Hospital with minor injuries.
Snr Sgt Butterfield said the driver was fortunate to have received only ''superficial injuries'', given the seriousness of the accident.
''I guess it's a timely reminder for everybody, given the weather we're facing at the moment, to drive to the conditions, and drive with caution - especially on that road.
''Black ice is one of those things that you can't see, so you have to treat it as though there may well be ice, particularly in shaded areas.''
The road was closed briefly while the accident scene was cleared.
