Is that a penny?
Driving a truck is a pretty dangerous job. If you don’t believe us, try playing Euro Truck Simulator and see whether you can keep your eyes open long enough to deliver your cargo. Yeah, fatigue is the biggest hazard of trucking. That and slippery roads.
What happened is that the driver lost control while driving this semi over a patch of ice. The truck crashed head-first into the sides of a bridge and fell several feet. Somehow, the truck’s cargo kept it from falling down completely, allowing the driver to climb out to safety. Talk about lucky.
