The Correct 75 Point Response is:

Dump back from the edge.
Make sure the dump point is level so the truck is not tilted while dumping.
Make sure the material in the box is free flowing (Hung material raises the center of gravity dangerously high.)
Do a pre-shift dump site inspection, looking for evidence of unstable ground.
Drive into the dump area with the driver’s side of the truck facing the dump edge to allow you to look for signs of unstable ground prior to each dump.
When passing the base of a stockpile, make sure no one is loading out at the toe.
When possible, check that the stockpile slope is at or below the angle of repose.
Be sure all dump point berms are in good condition and at least mid-axle height.
Never use the dump point berm to stop your truck prior to dumping.
Never accelerate rapidly from the dump point berm.
