This is the shocking moment a severe case of road rage between two SUV drivers almost ends in the pair crashing as they run each other off a busy highway.

The dash-cam footage, captured by Michael Wilson, shows two drivers fighting for dominance on the 32 West in Columbia, Maryland.

The road wage war starts after the white SUV cuts off the black one and the retaliation is swift.

The black car blocks the white car by pulling out in front of it and coming to a complete stop.

Michael says it was then that he realised that things between the two cars has escalated.

'Having not noticed these previous events, I assume the black SUV is disabled and is pulling over to get out of the traffic,' he said.

'I vacillate between trying to get close enough to capture this for possible police involvement and trying not to get involved myself.'

The two cars overtake each other as they fight for dominance on the four lane highway.

The reckless road rage almost ends in the drivers crashing as the pair take their fight off road and drive along the grass verge.

The black SUV almost runs the white SUV into the guide rail before the cars drive back onto the road.

Completely ignoring the highway lines the pair continue to drive in front of each other before dramatically stopping.

The footage ends as the white SUV stops in front of the black SUV and Michael, who has captured the whole debacle on dash-cam footage, drives away.
