When traffic lights are malfunctioning, who should yield?

Answer: D — Nobody

When traffic lights are malfunctioning, the proper course of action is that drivers treat the intersection as if it were a four-way stop. In this situation, no one should assume right of way based solely on the traffic lights, as the lights can no longer provide the necessary guidance for safe navigation. Instead, all drivers must proceed with caution, yielding to other vehicles and pedestrians as appropriate. This method helps to prevent confusion and ensures that traffic flows smoothly despite the absence of functioning signals. Being alert and communicating with other drivers can lead to safer outcomes at intersections during traffic light malfunctions.
