About 20 years ago, they were installing new high voltage power lines through the mountains behind where I lived. They had a dirt access road up to the area. A hugh crane truck was coming down the dirt road similar to the one in these pictures and he couldn't slow down enough for a sharp curve. He went off the edge when rounding the curve. There was nothing left of the truck. It tore the axles off the frame as well as the cab, motor, trans, fuel tanks, and the crane. There were pieces everywhere. The driver survived, but he was pretty messed up. I walked up to the site and couldn't believe how it totally ripped everything off the frame. They cleaned it up, and after they were done, you wouldn't know anything happened except for the hugh gouge marks in the dirt.
