What does it mean if a traffic signal is out?

When a traffic signal is out, it typically means that the traffic signal is not functioning correctly, often due to a power outage or malfunction. In such cases, it is important for drivers to exercise caution and ensure safety at the intersection. Treating the situation as a four-way stop is the correct approach because it requires all vehicles approaching the intersection to come to a complete stop and take turns proceeding through it. This method helps to prevent accidents and ensures that traffic is managed fairly and effectively in the absence of working traffic signals.

In contrast, continuing to drive as usual could lead to confusion and potential collisions, while treating it simply as a stop sign might not account for all vehicles approaching from different directions. Speeding through the intersection is dangerous and disregards the need for caution when faced with an unexpected situation like a malfunctioning signal. Therefore, recognizing the need to treat the intersection as a four-way stop is crucial for maintaining safety on the road.
