The guy driving the semi is clearly an idiot, but what about the guy driving the white pickup truck? Is he not smart enough to realize what is about to happen? That guy deserves a dumbass award. 

Drving a semi truck must suck. You basically sit all day and watch cars pass you by. I really think this driver knew his bed was sticking straight up and just didn't care. He needed some entertainment after driving for 7 hours straight. I would of probably done the same thing.

The guy in the white truck has no excuse though. Driving that close when you can clearly see what is about to happen is just asking to get hurt.
