How Can This Gigantic Truck Turn?

I've seen some long trucks carrying wind turbine blades so big that they defy belief. But I've never seen a truck carrying two of them. How can this thing turn without trashing all the other vehicles on the road?

I've checked it in Photoshop, and I have found no evidence of image manipulation whatsoever. [Thanks Oscar!]

Note: Apparently we were all blind in Gizmodo this morning. It's two trucks together, "joined" by an optical effect. Apologies.
