When a traffic signal is malfunctioning, what should you do?

Treat it like a four-way stop
Follow the posted speed limit
Treat it like a yield sign
Come to a complete stop

The correct answer is: Treat it like a four-way stop

When a traffic signal is malfunctioning, it may not be clear who has the right of way. Treating it like a four-way stop means that all vehicles must come to a complete stop and then proceed in the order they arrived at the intersection. This option ensures the safety of all drivers and is the best course of action in this situation. Following the posted speed limit (B) or treating it like a yield sign (C) may be dangerous, as it may not take into account other drivers who may be unaware of the malfunction or not following the same behavior. Coming to a complete stop (D) is also incorrect as it does not address the issue of determining who has the right of way.
