How should a driver respond to a traffic signal that is malfunctioning?

When responding to a traffic signal that is malfunctioning, treating it as a four-way stop is the correct action. This means that all drivers approaching the intersection, regardless of the direction they are coming from, must stop at the intersection and yield to any vehicles that arrived before them. This approach helps to maintain safety and order at intersections where signals are not functioning, as it allows for controlled movement of vehicles and pedestrians.

Understanding this best practice is crucial for minimizing the risk of collisions. By treating the malfunctioning signal as a four-way stop, drivers ensure they are following traffic laws designed to promote safety in situations where the usual traffic control measures are not operational. This action also emphasizes the importance of yielding to other drivers, which is essential in reducing confusion and potential accidents in such scenarios.
