A three-way car crash is causing commuter chaos in Wellington tonight as drivers face a long trip home.
The pileup happened about 4pm on State Highway 2 in the northbound section of the road, near the Nguaranga interchange.
Police say a van towing a trailer collided with two cars, one of which flipped.
Senior Sergeant Steve Braybrook said the crash was cleared "pretty quickly".
"The traffic is flowing but very slow," he said.
