A southbound lane of State Highway 1 at Lookout Point in Dunedin is blocked by a jackknifed tanker after it skidded on diesel which had spilled down the hill towards Caversham yesterday afternoon.
Police are investigating the nature of the spill which also caused another truck to skid. Police and the Fire Service were called to the incident about 1.15pm.
Senior Sergeant Bruce Ross said a tanker heading up the hill slipped on the diesel and jack-knifed across the left southbound lane.
Shortly afterwards, another truck skidded on the slick, he said.
Traffic was delayed while the diesel was cleaned off the road and the affected area covered with grit.
No-one was injured in the incident, and no other vehicles were affected, Snr Sgt Bruce Ross said.
It was not known how the diesel had spilled.
