What is the correct order of the IPDE cycle steps?

• A. Observe, Identify, Predict, Decide, Execute
• B. Identify, Observe, Predict, Decide, Execute
• C. Observe, Identify, Predict, Decide, Execute
• D. Observe, Predict, Identify, Decide, Execute

Answer: (C)

In the IPDE cycle, you start by observing the driving scene to gather information about the road, traffic, signs, and pedestrians. Then you identify any hazards that you’ve observed. After that, you predict how those hazards might develop or how other road users might act, considering possible scenarios. Next, you decide on a safe course of action to reduce risk. Finally, you execute the action you’ve chosen, such as slowing down, changing lanes, or stopping. For example, if you notice a ball rolling onto the street and a child nearby, you observe the scene, identify the potential hazard, predict that the child may run onto the road, decide to slow and stop if needed, and execute by braking smoothly. This order matters because you can’t predict or decide effectively without first observing and identifying what hazards exist.
