Sergeant Matt Lee, of Dunedin, said police were called to the intersection of Hillside Rd and Braemar St on Monday afternoon.
A 16-year-old driver was waiting at a stop sign while trying to pull out of The Warehouse carpark when the driver in the vehicle behind her started to honk impatiently.
This caused the teen to panic, move forward into traffic and hit another vehicle at low speed, Sgt Lee said.
No injuries were reported.
The intersection was blocked for a short time and both vehicles were towed.
