Video: Road rage incident ends with outrageous helmet headbutt
After almost being run off the road by a truck, a motorcyclist takes it on the driver.
The video shows a truck bizarrely drive on the wrong side of the road, almost running a biker off the road.
Understandably, the motorcyclist isn't too chuffed with this but the driver of the truck seems to think he is the victim, getting right up into the biker's face.
That's when a the bike passenger decides to end the confrontation in a very violent way.
