Footage has emerged of a road rage battle on a stretch of expressway in Adelaide.
Another driver captured the dispute between a Suzuki and a van on the Port River expressway, travelling north.
The Suzuki pulled up alongside the van, before the driver was seen hurling bottles at high speed.
The person who filmed the video says the argument began at Semaphore, when the car cut the van off.
They said the drivers screamed and swore at each other, as they made their way onto the expressway.
South Australian Police are investigating.
