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

Answer: B — Proceed with caution and be prepared to stop

When faced with a malfunctioning traffic signal, the appropriate response is to proceed with caution and be prepared to stop. Traffic signals are designed to manage the flow of vehicles and pedestrians safely, and a malfunction creates uncertainty for all road users. By approaching the intersection with caution, drivers can assess the situation more clearly and make safe decisions based on the actions of other vehicles and pedestrians. It's essential to remember that while the signal is not functioning, it does not mean that it has no effect on traffic rules. Malfunctioning signals require drivers to treat intersections similarly to those without signals, often requiring them to yield to cross traffic or pedestrians. This cautious approach allows for a safer outcome as drivers can react to any unpredictable elements that might arise. Being prepared to stop emphasizes the importance of being vigilant and ready to react, which is crucial in maintaining safety for everyone on the road.
