>> there's a car driving behind a larger truck. and then the truck goes to turn and smashes right into the front of another truck. >> actually another vehicle that stopped just ahead, and i suspect both of these drivers were trying to avoid some sort of situation involving that vehicle. >> your eyes aren't playing tricks on you. the video shows a man flipping through the windshield. >> standing there, thinking i just got into a car wreck. i literally just came out of the front window, but i'm completely fine. >> when the driver of the blue truck walked away, it's like he's playing cool, yo, i'm all right. i got it. >> i think he's scratching his head because that's a natural movement when you're unsure what just happened. so i love that he did that because he wasn't freaking out. he was just kind of contemplating what just happened. >> crazy crashes aren't always between two vehicles on the road.
