Concluding that you need to reduce space is an action associated with which IPDE step?

The action of concluding that you need to reduce space is associated with the 'Decide' step of the IPDE process, which stands for Identify, Predict, Decide, and Execute. In this context, the 'Decide' step involves making a judgment based on the information gathered in the earlier steps—especially what you have identified and predicted about the potential risks and movements of other road users.

When you identify potential hazards, and then predict how these hazards might affect your driving, you arrive at a point where you must decide on the best course of action to ensure safety. If the situation suggests that there might be a lack of sufficient space to maneuver safely, the decision to reduce space—perhaps by slowing down, changing lanes, or increasing following distance—becomes vital. This decision-making aspect is critical for maintaining safe driving practices and responding appropriately to dynamic traffic situations.
