Former world champion boxer Chris Eubank has been found guilty of taking a lorry without the owner's consent.
Eubank threatened to "deck" the driver, the court heard
But the ex-world super-middleweight champion was found not guilty of aggravated vehicle taking.
Eubank told Brighton magistrates the lorry blocked his way when he took his children to school.
He was given an absolute discharge. The court had heard claims that Eubank, of Upper Drive, Hove, had threatened to "deck" the lorry driver.
The court heard from Scottish Courage employee Gary Chandler who claimed Eubank ran at him, swore and started a row before entering the cab.
Several drivers were beeping their horns while the 35ft-long truck was being unloaded in February, the court heard.
It was claimed that Eubank was told the delivery was nearly finished, but he jumped into the cab, drove the lorry 150 yards along the road and hit a sign.
Prosecutor Madeleine Reardon said Eubank had told his children that what he did was wrong.
She told the court he had admitted getting into the vehicle and driving and had claimed "it was the gentlemanly thing to do".
Ms Reardon also claimed Eubank had said he did not remember causing damage but did offer to pay for it.
Mr Chandler said the former boxer ran at him and started a row
Eubank was ordered to pay £450 court costs.
He was also given six points on his driving licence in relation to a charge of driving without insurance which he had previously admitted at another hearing.
And he was fined £90 in relation to fixed penalty notices incurred earlier this year.
Speaking outside court, Eubank, said he was pleased with the outcome.
"You can't get a better result than that," he said.
"What I did was right. They were wrong...if I had paid any penalty at all it would have been sad.
"We all have to police the community. If you don't it's only a matter of time before we are taken advantage of by people who are bullies."
Asked if he would do the same again, he replied: "Absolutely...no matter what the result."
