A Wangaratta truck driver is counting his blessings after his truck was hit by a mystery missile on the Hume Freeway where it crosses Oddies Creek on Wednesday night.

He believes “kids” threw something heavy at his truck because “I don’t think there would be an adult who would be that stupid”.

Shane Garner was heading north about 8.30pm when his truck was hit.

Mr Garner said there was a loud bang when the missile struck but because he was unsure what had happened and didn’t see who might have thrown it, he kept driving.

But curiosity got the best of him and he stopped to inspect the truck on Thurgoona Drive.

He found the missile had hit the passenger side of his truck above the fuel tank.

“There was a bloody big dint,” he said.

“I didn’t see anyone throw anything.”

Mr Garner said the missile could have caused serious damage or distracted him from driving.

“If they are caught, they should be punished for it,” he said.

Albury truck driver and Australian Trucking Association board member Doug McMillan, who has had 45 years in the business, said he knew of several people being killed or injured by objects being thrown.

He said he had seen several pieces of railway ballast on the Lincoln Causeway on Wednesday night and feared they might have been thrown at vehicles by “bored kids”.

“They think they’re funny, but it’s a pretty bloody dangerous thing to do,” he said.

“It’s a stupid thing to do.”

Wodonga Sgt Damian Bould said while such incidents were rare, they were not unheard of.

“We don’t get many reports of it,” he said.

“They do pop up from time to time.”

Albury’s Insp Anthony Moodie said there hadn’t been any reports of similar incidents this week.

He said many highway overpasses were covered by protective screens to avoid such incidents.
