Show answer & explanationAnswer & explanation
Correct answer: A. Treat the intersection as if it were controlled by a STOP sign in all directions.
When a traffic light is not working, it should be treated as an all-way stop. All drivers must stop and then proceed only when it is safe to do so, following right-of-way rules for an all-way stop.
Why the other options are wrong
- B. Flashing headlights is not a recognized procedure for a non-working traffic light and does not ensure safety.
- C. While yielding is part of an all-way stop, the primary action is to stop first, not just yield to the right.
- D. Proceeding without stopping is dangerous and illegal, as other drivers may not be aware of your intention.
Non-Working Traffic Light
A traffic signal that is not illuminated or is flashing irregularly, indicating a malfunction.
- Treat as all-way stop.
- Stop before entering intersection.
- Proceed when safe, following right-of-way rules.
Memory trick: When the lights go out, treat it like a stop-out.
