If a traffic signal is malfunctioning, you should treat it as?

Answer: A — stop sign

When a traffic signal is malfunctioning, it is important to treat it as a stop sign to ensure the safety of all road users. Stopping at an intersection when the signal is not functioning correctly is crucial because it allows all drivers to assess the situation, check for other vehicles, pedestrians, and cyclists. This approach minimizes the risk of accidents at intersections, especially where uncertainty exists about right-of-way. In normal circumstances, drivers would proceed through a green light, but when the signal is not working, this assumption could lead to dangerous encounters with other vehicles or individuals. By treating the malfunctioning signal as a stop sign, drivers can approach the intersection cautiously, ensuring that they yield to any traffic already in the intersection or to the right-of-way of pedestrians, thus maintaining safety on the road.
