The shocking moment a Ford Focus driver cut in front of another motorist following a late motorway exit has been caught on camera.
The footage, which was recorded on the M1 outside Northampton, begins with the light blue Ford pulling off at junction 15 at the last minute.
With the indicator still flashing that the driver wants to turn left, the Focus follows another car closely as they travel up the motorway off-ramp.
The two vehicles and the car with the camera stop at a red light on a roundabout. When the lights turn green the cars follow the lanes around to the right, but the Focus decides to shoot straight over and return to the M1.
Instead of slowing to pull in behind the car to their left, the driver accelerates across the front, forcing them to brake to avoid a crash.
