That's a bad day right there.

It's not clear where this happened exactly, but a dash cam video of the incident shows an 18-wheeler that took a turn too wide on the highway, unwittingly hooking the back end of its cargo โ€” a huge beam โ€” onto a guard rail beside the road.

The beam falls over, and in short order, the cab goes with it. That's gotta suck.

Hat tip to Arpad!
