What does a flashing yellow traffic light mean?
- Merging traffic
- Proceed with caution. ✓
- Pedestrian crossing
- Come to a full stop.
Answer: B. Proceed with caution.
A flashing yellow light means you proceed with caution, so the correct choice is to proceed with caution.
Why this is the answer
The traffic signals section of the manual lists the flashing yellow light and says to drive with caution. It does not tell you to stop and it does not give any other driver that light the right-of-way over you. The same list sets flashing red apart, saying it works like a stop sign, which shows the two signals do different jobs. So when the light flashes yellow, keep going but pay attention to what is happening around you.
Why the other answers are wrong
- A. Merging traffic — The manual gives no meaning about merging traffic to a flashing yellow light; it only says to drive with caution.
- C. Pedestrian crossing — Nothing in the passages ties a flashing yellow light to a pedestrian crossing, so that is not what the signal means.
- D. Come to a full stop. — Coming to a full stop is what the manual attaches to a flashing red light, not a flashing yellow one.
Remember it
Flashing yellow is the lighter warning: ease off and keep moving, while flashing red makes you stop like at a stop sign.
