A police officer is regulating the traffic at a crossroads even though the traffic lights are in operation. What applies?

In situations where a police officer is directing traffic, their signals take precedence over both traffic lights and traffic signs. This is based on the principle of traffic order where a police officer's instructions are meant to ensure safety and manage traffic flow effectively, especially in complex or emergency situations. Therefore, while traffic lights and signs provide important guidance under normal circumstances, the directions given by law enforcement should always be followed. It is crucial to recognize the authority of police officers on the road, as their role is to ensure public safety.
