When can you disregard a signal given by a police officer directing traffic?

The correct choice indicates that you should never disregard a signal given by a police officer. Police officers directing traffic are authorized to manage the flow of vehicles and pedestrians, and their signals take precedence over standard traffic signals and rules.

When an emergency vehicle approaches, while it is crucial for drivers to yield to that vehicle, it does not provide a justification for ignoring an officer's direction. Instead, drivers must still follow the officer's instructions, as they are trained to ensure the safety of all road users in such situations.

Even if there is a conflict between the officer's signals and traffic signals, the officer's commands must be followed for safety reasons. Traffic signals serve as guidelines for drivers, but in situations where a police officer is present and directing traffic, their authority is paramount.

Thus, it is imperative to obey an officer's directions at all times, regardless of other circumstances that may be present.
