How should you react to a traffic signal that is not working?

When a traffic signal is not functioning, it is crucial to prioritize safety at the intersection. Treating the intersection as a four-way stop is the correct response because it establishes a clear protocol for all drivers present. This means that all vehicles must come to a complete stop, and then proceed based on the rules of yielding: the first vehicle to arrive at the intersection goes first, and if two or more vehicles arrive simultaneously, the vehicle on the right has the right of way.

This approach minimizes confusion and potential accidents, as all drivers will operate under the same rules, making the situation more predictable. By adhering to the four-way stop protocol, drivers can effectively manage the risk associated with the malfunctioning signal, ensuring safer navigation through the intersection.

Continuing through the intersection, waiting for the signal to reset, or using the horn can lead to unsafe scenarios, as they do not conform to standard traffic practices.
