Question: What is the primary hazard associated with driving an articulated haul truck too close to the edge of an active stockpile, particularly when backing up to dump?

Answer options: ✅ The risk of the truck sliding down the face of the pile due to an unstable edge or ground collapse.

• Difficulty in maneuvering the truck away from the pile after dumping.
• Increased wear and tear on the truck's tires from contact with sharp aggregate.
• Reduced visibility for the operator, potentially causing collision with other equipment.

Correct answer: The risk of the truck sliding down the face of the pile due to an unstable edge or ground collapse.

Explanation: Driving too close to the edge of a stockpile, especially with a heavy load, presents a serious hazard of ground collapse and the truck sliding or rolling over, as outlined in general heavy equipment safety guidelines.
