What does a flashing red beacon above an intersection signify?
- Come to a full stop and proceed when safe to do so ✓
- Immediately turn right
- Traffic from all directions must stop
- Proceed with caution
Answer: A. Come to a full stop and proceed when safe to do so
A flashing red beacon above an intersection means you must come to a full stop and proceed only when it is safe to do so.
Why this is the answer
The handbook states that a flashing red beacon above an intersection or stop sign requires a complete stop. You may move through the intersection only when it is safe. That is exactly what the correct choice describes: stop fully, then continue when the way is clear.
Why the other answers are wrong
- B. Immediately turn right — A flashing red beacon calls for a complete stop; the passage gives no instruction to turn right immediately.
- C. Traffic from all directions must stop — The passage says you must stop, but it does not state that traffic from every direction is required to stop.
- D. Proceed with caution — Proceeding with caution is what the handbook associates with a flashing yellow beacon, not a flashing red one.
Remember it
Treat a flashing red beacon like a stop sign: full stop first, then move only when safe.
