Motorists watched on as two men had a full blown fight in the middle of a motorway carriageway.
The incident occurred at around 12.45pm on December 9, when the drivers of a white Ford Escort Van and a Black Volvo V40 car became embroiled in what police described as a "road rage" incident on the M40 northbound near Bicester, between junctions 9 and 10.
The cars collided into the central reservation. The occupants of the vehicles then started a fight on the carriageway, with both men suffering minor injuries.
