Final answer:
It is true that state law mandates a full stop and yielding the right-of-way at intersections where traffic lights are malfunctioning or unpowered, ensuring safety for all road users.
Step-by-step explanation:
It is true that state law requires you to come to a complete stop and yield the right-of-way if you approach an intersection and the traffic lights are out of service or do not operate correctly. This rule emphasizes the need for driver vigilance to ensure the safety of all road users, including pedestrians and other vehicles already in the intersection. In situations where the standard traffic control devices are non-functional, treating the intersection as if it has a stop sign from all directions is usually advisable until the traffic lights are repaired.
