If a machine shows signs of instability on a slope, what is the immediate safe action?

• A. Continue moving slowly while monitoring balance.
• B. Stop movement, engage parking brake, and reassess the slope and plan before continuing.
• C. Immediately reverse the machine to a lower point.
• D. Increase the speed to regain traction.

Answer: (B)

On a slope, instability means the machine can tip or slide. The safest move is to stop moving, engage the parking brake to prevent any creep, and then reassess the slope, ground conditions, and your plan before continuing. This pause helps prevent a rollover and gives you a chance to determine if conditions are safe, if you can reposition to firmer ground, adjust ballast, or choose a different route. Continuing to move, even slowly, can let the center of gravity shift and increase the risk of a rollover. Reversing or increasing speed would likely make things worse and should not be used as a remedy.
