Final answer:
When approaching an intersection with a non-functioning traffic signal, it is important to treat it as a four-way stop to ensure safety and prevent accidents.
Step-by-step explanation:
When approaching an intersection with a traffic signal that is not functioning, it is important to treat it as a four-way stop. This means that you should come to a complete stop, yield to any vehicles or pedestrians who arrived first, and then proceed with caution.
This is necessary to ensure safety and prevent accidents. Following the rules of a four-way stop when the traffic signal is not functioning helps maintain order and prevent confusion.
Remember to always be cautious and aware of your surroundings when approaching an intersection without a functioning traffic signal.
