Green means go, red means stop, and down certainly means out.
That was the case for a new traffic light at the intersection of Anzac Ave and Frederick St, Dunedin, which was officially turned on last month only to be knocked over yesterday.
A late model Ford ute crashed into the traffic light, resulting in police and ambulance services being called to the scene, about 1.30pm.
No-one was injured.
Police inquiries are continuing.
