Footage captures the terrifying moment the two drivers almost came to blows. The bust-up starts when the van driver overtakes the grey Vauxhall Vectra and cuts him up as they drive up a hill at 30mph close to Northampton town centre. The manoeuvre enrages the Vectra driver who accelerates and drives across the front of the van, causing a small collision. The road rage driver, wearing a baseball cap, then dashes from his vehicle and goes to attack the van driver, banging the door of his van so hard the whole vehicle shakes. A woman travelling with him in the Vectra then gets out and warns him that the incident is being filmed on a dashcam visible through the front window.
