This is a logging truck driving on the edge of a mountain. And I do mean the very edge. Excuse me while I scream for a few minutes straight.
The video comes from the pucker-worthy YouTube channel of Schrauberitsch, a logger who appears to be based in the Austrian Alps driving a Volvo truck, as seen here.
According to Statistik Austria, only four truckers carrying loads of over 12t died between 2009 and 2012, though there were 196 injuries reported in that time period. Maybe Schraberitsch knows what he's doing.
This Logging Truck Driving On The Edge Of A Mountain Is Terrifying
