Hope I did this right but this is quite strange if it's not a fake. What can be the cause of this? <iframe width="640" height="360" src="http://www.liveleak.com/ll_embed?f=5d9912f42cef" frameborder="0" allowfullscreen></iframe>
It's a downed line being dragged by the truck on the right (black circle). Just watch the reaction of a pedestrian (red arrow) as he runs up to the truck warning of the problem and stopping the truck.
Nope not fake. Just someone that doesn't know the simple task of posting a embedded video URL posted it.
