When a traffic officer is present at an intersection with working traffic lights, which signals must drivers follow?

Answer: B — The police officer's signals

When a traffic officer is present at an intersection, drivers must follow the signals provided by the officer. The authority and guidance of a traffic officer take precedence over standard traffic signals, including working traffic lights. This ensures that the flow of traffic is managed according to the officer's directions, which may be necessary for various reasons, such as an emergency situation, road conditions, or high traffic volume. Obeying the signals given by the traffic officer is essential for ensuring safety and compliance with the law, as these officers are trained to handle complex intersection situations effectively. This rule protects both drivers and pedestrians, as it provides a clear and authoritative guide on how to navigate the intersection safely. In contrast, following traffic light signals, pedestrian signals, or signals from other vehicles does not apply when an officer is directing traffic, as these can lead to confusion and potentially dangerous situations if not aligned with the officer's instructions.
