Show answer & 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.
