Driver injured in roadwork truck smash was speeding - police

A man who was seriously injured when his car hit a roadworks truck near a motorway off-ramp in Auckland on last night was speeding, say police.

The man suffered critical but not life-threatening injuries when his car hit the truck about 9.15pm near the Wellesley St and Port off-ramps.

Police spokeswoman Noreen Hegarty said the Port exit was partly cordoned off for roadworks.

The man was driving faster than the restricted limit in the area, she said.

His car hit a truck with flashing lights and it took an hour to cut him from the car before he could be taken to Auckland City Hospital.

It is understood the man suffered serious injuries to his legs and arms, and had surgery about midnight. He was believed to be alone in the car.

The Auckland District Health Board was unable to say what condition the man was in.
