What does it signify if a signal light is not functioning?

When a signal light is not functioning, it indicates that the traffic control device is out of service and cannot provide the necessary guidance for drivers. In such cases, the safest course of action is to treat the intersection as a four-way stop. This means that all vehicles approaching the intersection should come to a complete stop and yield the right of way to vehicles that arrive first or to the right in the event of simultaneous arrivals.

This approach ensures that drivers are exercising caution and following the general rules of right-of-way, thereby minimizing the risk of accidents at an intersection where the usual traffic control signals are absent. It promotes safe navigation through the intersection, giving each driver a chance to assess the situation before proceeding.

In contrast, continuing to drive as normal could lead to confusion and a higher likelihood of collisions, as drivers may not anticipate oncoming traffic that is also unsure of how to navigate without a functioning signal. Trying to reset the signal by kicking the box is not only ineffective but could also result in damage or malfunction. Following the traffic of the busiest street does not address the critical need for orderly control when signals fail and can lead to further complications.
