Final answer:
If a traffic signal is out of order, proceed with caution as you would for a yield-right-of-way sign.
Step-by-step explanation:
If a traffic signal is out of order, proceed with caution as you would for a yield-right-of-way sign. When a traffic signal is not functioning, it means that the automated control of the intersection is not working properly. In this case, drivers should treat the intersection as an uncontrolled intersection and follow the right-of-way rules.
