What does it mean if a traffic officer is directing traffic?

When a traffic officer is directing traffic, it means that drivers should prioritize the instructions given by the officer over traditional traffic signals and signs. This is crucial because the officer is there to manage the flow of traffic in real-time, often responding to changing conditions on the road that may not be addressed by automated signals. For example, if an intersection is particularly busy or there's an unexpected event, the officer's direction helps to maintain safety and order among vehicles and pedestrians.

While traffic signals are designed to regulate vehicle movement, they may not account for specific situations like accidents, road construction, or other emergencies where human judgment is required. Therefore, it is essential for drivers to adhere to the officer's commands to ensure safety for all road users. In contrast, the other options imply a misunderstanding of traffic laws, suggesting that signals can be ignored or suspended, which is not the case when an officer is present and actively directing traffic.
