B-double truck filmed swerving across road during journey between Gawler and Williamstown

A passenger filmed a B-double swerving in and out of its lane on regional South Australian roads, narrowly missing oncoming vehicles.

A B-double truck has been filmed swerving in and out of its lane in country roads and towns – including crossing over the white mid-line, as it becomes perilously close to an oncoming car.

Michelle Van Der Walle-Oates was driving as her partner filmed the truck travelling between Gawler, Sandy Creek, Cockatoo Valley, Williamstown and Birdwood last week and called the police because she was so concerned about the movements of the heavy vehicle.

“My first thought were that I was going to see a crash or someone die,” she said.

“We just thought it was dodging put holes at first but it kept driving erratically so we started filming it.

“When it got even worse we called the police.”

Ms Van Der Walle-Oates said she had followed the truck for the 45 minute drive home to Williamstown on Friday and recorded about 26 minutes of the journey which had been condensed into a four-minute video that she posted to Facebook.

In the footage, the B-double truck can be seen swerving across a while line in the middle of the road as a car approaches from the opposite direction in the oncoming lane.

The truck then corrects back into the left-hand lane.

On other occasions, the truck can be seen repeatedly moving across the white line at the edge of the road to travel on the road’s shoulder.

The footage also shows the truck crossing partially over into double white lines of the oncoming lane, before moving back into its left-hand lane.

Ms Van Der Walle-Oates, who has a truck licence but has not driven a B-double, said there was no wind or other weather reason for the truck to repeatedly veer across the road.

She the scariest moment was when the truck tuned into the narrow Williamstown streets.

She implored others to take care on the roads and consider taking a rest if required.

“If you don’t think you can drive, have the confidence to say I can’t do it,” she said.

“Just be careful.”
