Irresponsible US drivers take their showdown across highway's central reservation

Shocking video footage shows two drivers moving erratically across many lanes of traffic and even mounting the central reservation and the roadside.

Filmed on interstate 205 in Portland, Oregon the drivers can be seen veering on and off the road in a tense road rage battle.

The filmer later said: "I came around the corner to the metered on-ramp, and the two cars from the video were there.

"The silver Nissan was blocking the progress of the Durango, who was trying to get around the Nissan.

"I’m not sure if the Nissan got cut off or what led to this, but the Nissan actually impacted the Durango right before I got the camera out.

"After that, the video ensued."

The footage was captured on October 21.
