10 Extreme Dangerous Idiots Biggest Truck Fails Heavy Equipment Driving Machines Fails Working

 It's always a mystery to me how I can't sit in a moving car for more than 5 seconds without it beeping wildly, if I'm not wearing my seatbelt yet, but these guys manage to ram an upward facing truck bed into highway overpasses and signage! Is there seriously no system in place to warn them  If it wasn't for the red circle in some of these I would have never seen what happened. The giant explosions and falling debris would gone completely missed.  This difficulty with load limits suggests that~  cultures that invent heavy machinery have a better chance of using it correctly than the many many cultures that have NOT invented the technology.  some really good videos on here , lots I have not seen before, I especially love the ones where drivers try and go under bridges with the back of their tipper truck still fully raised .  There are some major screwups, but a few of these videos actually show some impressive skill as well as ingenuity - 6:20 , for example.  After dumping your dirt, make sure to leave the dump body up and don’t ever, ever check your mirrors as you drive along  Years ago, I spent many days and hours behind the steering wheel of a dump truck.  Improvements aside mechanically, I don't understand how you can not go through the basics of getting a load of dirt (or whatever) dumping your load and going back for another.   Nothing to complicated about that right, Well, in 10 minutes I could have my granddaughter doing it and become a 49er (in the union) in a day!  
I see these videos and I am so astounded to see drivers with their dump box high up in the and tooling down the highway. Before heading back for another load you lower the box, making sure the back gate is secure and go.  They put mirrors on everything going down the road, so why not use them especially big trucks.  I'd have been fired for doing something so stupid!
