An articulated dump truck operator is assigned to a hauling route where a portion of the road runs along the crest of a fill slope. The slope appears steep and there are signs of tension cracks near the edge of the road. What is the primary hazard this operator should be concerned about?

Question: An articulated dump truck operator is assigned to a hauling route where a portion of the road runs along the crest of a fill slope. The slope appears steep and there are signs of tension cracks near the edge of the road. What is the primary hazard this operator should be concerned about?

Answer options: ✅ Slope failure leading to the road collapsing under the truck's weight.

• Dust accumulation reducing visibility.
• Increased tire wear due to the slope angle.
• Difficulty in maintaining vehicle speed on the incline.

Correct answer: Slope failure leading to the road collapsing under the truck's weight.

Explanation: Tension cracks near the crest of a slope are a critical indicator of potential slope instability. The primary hazard is a slope failure, where the soil mass could give way, causing the road to collapse and the dump truck to tumble down the embankment, resulting in serious injury or fatality.
