What should a driver do if they encounter a traffic signal that is malfunctioning?

When encountering a malfunctioning traffic signal, treating it as a stop sign is the appropriate action. This protocol is established to ensure safety at intersections where the normal traffic control flow is disrupted. By treating the malfunctioning signal like a stop sign, drivers are instructed to come to a complete stop, assess the situation, and then proceed only when it is safe, allowing any vehicle or pedestrian right-of-way to pass. This approach helps prevent accidents and ensures a cautious and responsible response in an unpredictable situation.

The other responses suggest actions that could lead to unsafe driving behavior. Proceeding through without stopping disregards the critical need for caution at potentially dangerous intersections. Ignoring the signal if no other cars are around can create a false sense of security, as pedestrians or unexpected vehicles could be present. Reporting the malfunction to the police, while a responsible action in terms of ensuring future safety, does not address the immediate need for careful navigation through the intersection itself.
