A fault with the Claypotts junction traffic lights in Broughty Ferry caused tailbacks along the Arbroath Road.
The issue led to long queues on either side of the A92 Arbroath Road yesterday, at the junction where Claypotts Road meets the trunk road.
Commuters complained about the lights being out of sync, with not enough time being given for an appropriate number of cars to pass through the junction when the lights were green before they turned back to red. Similar complaints were made on Tuesday morning.
A council spokesman said there had been a technical issue with the lights.
