A traffic officer’s signal takes priority over which of the following?

Answer: A — Traffic signs and signals

A traffic officer’s signal takes priority over traffic signs and signals. This is crucial for maintaining safety and order on the roads, especially in complex traffic situations or emergencies. When a traffic officer is directing traffic, their instructions are considered authoritative and must be followed, even if they contradict existing traffic signs or signals. This ensures that officers can effectively manage traffic flow and respond to dynamic situations on the road. Traffic lights, while important for regulating vehicle movement, must yield to an officer's commands as officers are trained to make real-time decisions that may not be reflected by the current traffic control devices. Similarly, while emergency vehicle sirens indicate urgency, they do not override the direct instructions from a traffic officer, making the officer's signal the highest authority in such situations. The priority of the officer's signal is meant to protect public safety and facilitate smooth traffic operations.
