How should you react to a traffic signal that is not functioning?

When approaching a traffic signal that is not functioning, the appropriate response is to treat the intersection as a four-way stop. This means that all vehicles must come to a complete stop and yield to any traffic that arrives before them. If two or more vehicles arrive at the same time, drivers should yield to their right, following the general rules of courtesy and safety at uncontrolled intersections.

This method ensures safety, as it allows drivers a chance to assess the situation and react accordingly, reducing the likelihood of accidents that could result from assuming right of way at a malfunctioning signal. It emphasizes the importance of cautious driving and awareness of other road users, aligning with traffic laws designated for such situations.
