Chilly conditions in Otago this morning led to delayed starts for schools and warnings for motorists, with a car going off the road into Otago Harbour.
The car went into the water at Deborah Bay about 9.45am today, but police could not confirm whether an icy road was to blame.
The driver was the sole occupant of the car and was able to get out before it became submerged.
Southern District communications manager Nicholas Barkley said a passerby stayed with the driver until police arrived.
Dunedin police were notified about two other traffic incidents this morning, one an abandoned car in Mosgiel and the other a two-car collision on the corner of Portsmouth Dr and Strathallan St. No one was injured in the collision.
