Some videos need no explanation. The life of a trucker is hard. Long hours in the road and being away from your family can be tough. But what makes trucking especially dangerous (for truckers who have to navigate sketchy mountain roads) isn't the alone time, but the random boulder rolling down the side of a mountain. 

It's videos like this that make us thankful for whoever invented the dash cam. This trucker is going about his day when his dash cam captures a one-in-a-million moment when a boulder comes flying down the hill side and crushes the truck in front of him. 

And right after the first boulder, another comes mere inches away from his own truck. 

There is no word on if the person driving the first truck is okay, but were telling ourselves he is. But you know this guy is going to be telling this story at dive bars for as long as he lives, which, if he keeps driving this route, might not be too long after all.
