"Enraged over the collision he walked back to the victim and spoke in an abusive manner. He punched the victim once in the mouth causing his lower lip to split and bleed ... he required four stitches."
After calming down, Tucker gave his details to the victim who later went to the Masterton Police Station laying an assault complaint.
In explanation, Tucker told police he was angry as his young daughter was sitting close to where the man's car hit his, Mr Wilson told the court.
Defence lawyer Jock Blathwayt said Tucker was beside himself at the time.
"He tells me is that he was incensed. He was upset ... he reacted badly," he told the court.
"He says he apologised at the time ... it was spur of the moment."
Judge Walsh convicted Tucker of assault and ordered him to pay $300 reparation to the victim at $20 per week with the first payment to start on September 11. He also ordered him to pay $130 in court costs.
