On Friday it wasn’t fate, but a “bloody idiot throwing something” that shattered his windscreen on Highway One at the Wilmington turn-off, Mr Andrews believes.

On his regular run from Adelaide to Whyalla and back, Mr Andrews was heading north on Highway One at 100km/h with no vehicles immediately in front of him about 9.30am.

A State Emergency Services car and two or three other cars passed in the opposite direction when the laminated windscreen in front of him shattered.

“There is no way it was a stone flicked up,” Mr Andrews said.

“It has to be something thrown at me, either from the edge of the road or from one of the cars going the other way.

“I didn’t see anybody.

“There are some bushes beside the road there. I did a U-turn and went back but there was no one there.

“It was somebody in one of the cars most likely.”

Mr Andrews, from MacDonald Park, said he reported the incident to Port Augusta police.

“They (thrower) could have killed somebody. It almost came through and if it had been across a bit more who knows what would have happened,” he said

The object cleared the bug deflector above the grill, bounced on the bonnet leaving a gouge in the fibreglass and shattered the inside and outside sheets of safety glass, tearing the plastic laminate film between them.

It left a 25mm deep indentation almost 150mm long and 50mm wide in the glass.

Mr Andrews said he and the inside of the cab were showered in tiny glass shards.

“Lucky I was wearing sunglasses, I might have copped some in the eyes,” he said.
