When a traffic signal is malfunctioning, it is essential to prioritize safety and ensure that all road users are aware of the situation. Treating the intersection as a four-way stop is the correct approach in this scenario. This method allows all vehicles coming from different directions to yield and take turns, significantly reducing the chances of accidents that could occur due to confusion or misinterpretation of a broken signal. Adopting this practice means that each driver must come to a complete stop and assess the intersection before proceeding, ensuring that everyone has the opportunity to safely navigate through the area. This is a standard procedure outlined in traffic laws to manage such situations effectively. While the other options suggest actions that would not promote safety—such as continuing through at full speed, following the last signal displayed, or ignoring the signal altogether—these would increase the risk of collisions and misunderstandings among drivers. Treating the intersection as a four-way stop is the most prudent and safe response when faced with a malfunctioning traffic signal.
