What should you do if traffic signals are not functioning at an intersection?

Answer: B — Treat the intersection as a yielding stop

When traffic signals are not functioning at an intersection, it is essential to treat the situation as a four-way stop. This means that you must yield to vehicles that arrived at the intersection before you and proceed only when it is safe to do so. This approach helps maintain order and safety, as intersections without functioning signals can become chaotic with drivers unsure of who has the right of way. By treating the intersection as a yielding stop, you adhere to the principles of defensive driving. This practice reduces the risk of collisions and ensures that all road users are aware of their responsibilities. It's crucial to always remain vigilant and cautious in these situations, as other drivers may not follow the expected norms, being unsure themselves about how to navigate the intersection safely.
