Step-by-step explanation:
If you approach a traffic signal that has no light on, it is most likely out of order. In this situation, it is important to treat the intersection as a 4-way stop. This means that you should come to a complete stop at the intersection and yield the right-of-way to any other vehicles or pedestrians. Proceed through the intersection only when it is safe to do so.
