How should you handle an intersection with a malfunctioning traffic signal?

When encountering an intersection with a malfunctioning traffic signal, the appropriate response is to treat it as a four-way stop. This approach is in accordance with traffic laws in many jurisdictions, including Illinois. At a four-way stop, all vehicles approaching the intersection must come to a complete stop, assess their surroundings, and yield the right-of-way to any vehicles or pedestrians that are already in the intersection.

By treating the malfunctioning signal as a four-way stop, drivers can promote safety and prevent collisions. This method requires all drivers to focus on the traffic situation at the intersection, ensuring that everyone is aware of the other vehicles' intentions. It also helps to minimize confusion that can arise from a non-functioning signal.

In contrast, treating the traffic light as green could lead to dangerous situations, as it implies that it is safe to proceed without stopping, which might not be the case if other vehicles are approaching. Turning around or finding an alternate route may not always be practical or feasible in a busy area and could contribute to traffic congestion. Speeding through the intersection is unsafe and can lead to accidents, as it disregards the need for caution at a potentially hazardous junction.
