A CAR involved in a collision with a B-double truck at Ulmarra on Friday morning was allegedly seen driving erratically before the incident.

According to witnesses, the car, travelling south along the Pacific Highway, was allegedly overtaking several other vehicles and ducking in and out of traffic.

"A woman who was behind the car just before the crash said it overtook her, then she had to overtake them not long after before it passed her again and other cars," another witness said.

"She said they were driving crazy and she knew something was going to happen, that they were going to cause a crash."

As the woman called triple zero to report the car to police, the B-double truck, travelling north, and the silver car collided near the pedestrian crossing outside Ulmarra Public School.

"It happened about 100 metres in front of her," the witness said.

"It was so lucky it didn't happen during school time ... that would have been awful."

The silver car sustained extensive damage to the front and there was fluid leaking out of the B-double.

One man was able to remove himself from the damaged car, but a second male occupant remained trapped inside the vehicle for a short time.
