This scenario rarely happens in daily driving, which is exactly why it catches people off guard on the exam.
Here is one worth locking in:
If a traffic light is green but a police officer signals you to stop, which do you obey?
The officer's signal always overrides the traffic light, regardless of what color it's showing. This is one of the clearer "authority overrides automation" rules in the whole syllabus, but it's easy to blank on because it almost never comes up outside of an exam question.
Beyond police signals, this category also covers pedestrian priority at zebra crossings without lights, and what "priority" actually requires you to do as a driver.
Your turn. If there is a right-of-way scenario you keep mixing up, post it here. If you know the answer to someone else's, help them out.
