What should you do if you see a traffic signal malfunction?

When a traffic signal is malfunctioning, the safest and most appropriate action is to treat the intersection as a four-way stop. This means that all vehicles approaching the intersection must come to a complete stop and yield to any vehicles already in the intersection or those arriving at the same time. This method helps maintain order and safety in a potentially confusing situation where the normal traffic rules might not be clear due to the broken signal.

By treating the intersection as a four-way stop, drivers can communicate their intentions through their actions, making it easier for everyone to navigate the intersection safely. This method minimizes the risk of accidents that could occur if drivers proceeded through the intersection without stopping, as they would under normal green light conditions. This is particularly important in preventing collisions, as multiple vehicles may arrive at the intersection simultaneously.
