What should you do when approaching an intersection with non-working signal lights?

When approaching an intersection with non-working signal lights, treating it as an all-way stop sign intersection is the correct course of action. This means that all vehicles must come to a complete stop before entering the intersection, allowing drivers to assess the situation and proceed in a safe and orderly manner. This rule is crucial for preventing accidents at intersections where traffic signals are malfunctioning because drivers may have conflicting expectations if they assume the traffic light is functioning.

This approach promotes safety and enhances predictability among drivers. Each vehicle must yield to any traffic that has arrived at the intersection first, and if multiple vehicles arrive simultaneously, they should follow the right-of-way rules. Understanding this procedure is essential for maintaining clarity at various intersections, especially when signals are not operational.

Other options do not align with safe driving practices under these circumstances. Proceeding with caution without stopping doesn't provide the necessary structure to the intersection, while treating it as a yield sign could lead to confusion and possible collisions. Ignoring the intersection completely is also unsafe, as it could result in dangerous situations. Hence, treating it as an all-way stop helps establish clear rules for everyone involved.
