How should you respond to a traffic signal that is not functioning?

When responding to a traffic signal that is not functioning, treating it as a four-way stop is the appropriate action. This means that all vehicles arriving at the intersection must come to a complete stop and yield to any vehicles or pedestrians that arrive before them. This method helps to ensure safety and reduces the chance of accidents, as it establishes a clear protocol for navigating the intersection when the traffic signals are out.

Traffic signals are designed to control the flow of traffic, but when they are inoperable, they can create confusion and uncertainty. By converting the scenario into a four-way stop situation, it provides a system that promotes orderly and safe passage for all road users. This approach is generally mandated by traffic laws in many jurisdictions, including Maine.

Driving cautiously as if it were a yield sign or waiting for the signal to start working may not adequately address the potential hazards present at an intersection without functioning signals. Proceeding without stopping is definitely unsafe and could lead to dangerous situations, including accidents.
