A dump truck managed to tear down several overhead wires and a traffic light because the driver forgot one very important dump truck rule.

What this driver neglected was that when you dump a load, you're supposed to drop the dump box back down.

Why this guy forgot this simple, but very important rule, is anyone's guess. The worst part is, he managed not only to damage the overhead lines, but in the process wrecked the truck.

Fortunately, his mistake didn't create any major traffic accident other than his own. Now, he just has to figure out how to pay for all the damage. It's quite likely he won't be doing it by driving drive a dump truck.
