Final answer:
The 'Decide' step of the IPDE process is used when determining how to adjust speed or position, which is a crucial part of safe driving practice.
Step-by-step explanation:
When you are determining how to adjust speed or position, you are engaging in the 'Decide' step of the IPDE process. This approach is used primarily in driver's education to prevent collisions and ensure the safety of all road users. The IPDE process includes four steps: Identify, Predict, Decide, and Execute. 'Identify' refers to recognizing potential hazards in the driving environment. 'Predict' involves considering the potential actions of others and the consequences. 'Decide' is the step where you select the best course of action, such as adjusting speed or changing position. Finally, 'Execute' is when you carry out the selected action. So, in the context of adjusting your speed or position, 'Decide' would be the correct IPDE step.
