UPDATE 12.10pm: A 28-year old man and woman killed in yesterday's fatal Pacific Highway accident at Knockrow were in "an unfortunate place at the wrong time" when their sedan was crushed by an out-of-control semi-trailer, police have said.
Inspector Mick Dempsey of Richmond Local Area Command said the truck was travelling south on the highway about 3.40pm yesterday when it clipped the rear of another truck and swerved on to the northbound lane.
Insp Dempsey said the victims were waiting to turn on to the highway out of Ivy Lane, 750 metres north of Macadamia Castle, when the truck "rolled on top" of the stationary silver sedan.
Police have yet to identify the woman who died in the car, although he confirmed the male driver was from the Gold Coast.
There were no other passengers in the vehicle.
The 26-year old truck driver is also from the Gold Coast.
He was conveyed to Ballina Hospital where compulsory blood and urine tests were taken, and later released without injury.
Officers from the Crash Investigation Unit are continuing their enquiries.
Police were unable to say whether speed was a factor in the crash.
