Changes could be made to the busy Rolleston Drive and State Highway 1 intersection to stop traffic poles being hit by vehicles.
The intersection, which has about 25,000 to 30,000 vehicles drive through it each day, has had 17 incidents where traffic poles have been damaged in the past 11 years.
Senior Sergeant Pete Stills said most accidents are "generally" caused by people failing to give way to straight-through traffic when turning into Rolleston Drive.
"So really they're just incidents of poor driving," he said.
The intersection appears to even have its own Twitter page called Rolleston traffic light pole – detailing whether it has been hit or not.
