Captured on a dashcam, the video shows the driver of a black car weaving in and out of traffic on Monday afternoon. 

The footage was captured by Steve Knox about 4.30pm June 18 on the Princes Highway, just after the Jervis Bay turnoff heading south. 

Mr Knox said a combination of the driver’s speed, erratic manoeuvres and wet weather made for a very frightening situation. 

“It was pretty scary,” he said. 

“If he had of clipped any of the cars on the other side of the road [when he was trying to overtake] that would have wiped out me, and the other three or four cars around me,” he said. 

The driver of the black vehicle can be seen constantly crossing over into oncoming northbound traffic to overtake other drivers heading south. 

Since December 2017, eight people have been killed on the Princes Highway South of Nowra, and Mr Knox said he’d never seen anyone drive so dangerously than he did on Monday. 

“I drive that stretch of road everyday and there is always traffic, but I’ve never seen anyone do something so stupid,” Mr Knox said. 

“The driver needs to be locked up as far as I’m concerned.

“Driving like that would only have saved 20 or 30 seconds of the journey. Is it really worth it?”

Mr Knox said the driver could have caused a “huge accident”. 

“There are so many impatient drivers on the road who are just putting everyone at risk. Something needs to change,” he said. 

Mr Knox said he had received reports from other witnesses that the driver had been driving erratically from Berry and through Nowra.
