The truck driver behind a racially charged social media video has apologised to his victim and has had charges against him dropped.

Sunny Singh, the manager of a Port Augusta taxi company and local council nominee, was the subject of a video posted to a national trucking Facebook page that went viral last week.

The video shows a man in a truck directing racial slurs at a life-sized cut-out made from one of Mr Singh's election placards, which is eventually run over by the truck.

Mr Singh said he exchanged a phone call and text with the driver, fully accepting his apology.

"The text message said, 'I didn't want to hurt anyone, I understand I have upset your family, can you apologise to your wife and kids for me?'" Mr Singh said.

"I never wanted him to apologise to me, he upset the Port Augusta community and some other people.

"Now they're happy, I'm happy ... it wasn't personal."

Grant Moroney Trucking's contract with Mogas Fuel was suspended last week after the video went viral — something Mr Singh said he would change if he could.

"I asked if there was anything I could do to get his job back or his contract back, because I never wanted him to lose his contract," he said.

"I mentioned to him that if there was anything I could do to get his last contract back, then I'm more than happy to do it."

He said the decision to drop the charges relating to the removal of his election poster was an easy one.

"I didn't want him to get charged for anything to start with, that's not an issue," he said.

"It wasn't personal, I don't want to expend any hate between us."

He said the pair hadn't had a chance to meet in person as yet.

"We may meet by the end of this week," he said.

A spokesperson for South Australia police confirmed an investigation into traffic offences was ongoing.
