What should you do if traffic signals are malfunctioning at an intersection?

Answer: A — Proceed with caution and treat it as a four-way stop

When traffic signals are malfunctioning at an intersection, treating it as a four-way stop is the appropriate response. This means coming to a complete stop and giving the right-of-way to vehicles and pedestrians, following the rules typically applied at a stop sign. This approach promotes safety for all road users since everyone at the intersection will be stopping and assessing their surroundings, allowing for a clearer understanding of who has the right of way based on arrival times. Continuing to drive at normal speed can lead to confusion and potential collisions, as other drivers may not be following any signal controls, creating unpredictable situations. Following the last functioning signal may create further danger, as other drivers may not recognize or adhere to an outdated signal, leading to misunderstandings. Waiting for police direction can unnecessarily delay traffic and may not always be practical, especially if officers are unavailable or if there are many cars waiting. Thus, treating the intersection like a four-way stop ensures traffic flows more safely and orderly during a signal failure.
