Witnesses to crash on hwy sought

POLICE have called for witnesses to a head-on collision which left two people critically injured south of Grafton to come forward and assist crash scene investigators.

Three people were injured – two critically – in the Pacific Hwy crash about 250m north of the Wooli turnoff between 11am and 11.30am on Thursday.

It's believed the accident happened when the caravan, towed behind the Nissan Pathfinder, began to sway and the car veered into the path of the south-bound truck.

The collision between the eight-tonne pantech and the four-wheel-drive ripped off the front ends of both vehicles and caused the caravan to jackknife past the impact point.

The caravan “exploded” off its trailer and scattered its contents 80m up the highway and onto the road verge.

Ambulance officers said the middle-aged couple from Port Macquarie in the four-wheel-drive were trapped in the vehicle for about 15 minutes.

Both received chest injuries.

The female driver was taken by the Westpac Rescue Life Saver Helicopter to Coffs Harbour hospital and the male passenger was taken by road ambulance also to Coffs Harbour.

Both were listed in critical condition.

The driver of the truck was taken by ambulance to Grafton Base Hospital with a suspected broken ankle.

Both lanes of the Pacific Hwy were closed throughout the afternoon as police accident investigation personnel inspected the site and debris was cleared from the road.

There was a slight hitch during the rescue attempt when a piece of debris pierced the left front tyre of the ambulance which was ferrying the injured woman about 50m up the road to the helicopter.

Ambulance officers replaced the tyre at the scene.

The helicopter was also delayed for a few minutes when a warning light came on and the pilots radioed their base for advice.

Police want anyone who saw the collision, or the events leading up to it, to contact Grafton Police or Crime Stoppers on 1800 333 000.
