When encountering a traffic control device that is not functioning, treating it as an all-way stop is an appropriate action. This means that all drivers must approach the intersection with caution, come to a complete stop, and yield to any other vehicles or pedestrians that may already be in the intersection or approaching it. This approach ensures safety by allowing drivers to make their own judgments in the absence of clear signals from the traffic device.

It is crucial because an out-of-order signal can create confusion among drivers, leading to potential accidents. By adhering to this rule, drivers help maintain order and safety on the road while also respecting the right-of-way. The other suggested actions—ignoring the signal or proceeding at full speed—can significantly increase the risk of accidents, while treating it as just a yield sign does not provide the same level of caution and safety that is necessary in this situation.
