A yellow light that flashes on and off means:
- Stop and look for other vehicles, then go if there is no traffic.
- Stop and wait for a green light.
- Speed up to clear the intersection quickly.
- Slow down and proceed with caution. ✓
Answer: D. Slow down and proceed with caution.
A flashing yellow light means slow down and proceed with caution.
Why this is the answer
The handbook says flashing yellow lights are used at or just before dangerous intersections and also to alert you to warning signs such as a school crossing or sharp curve, and it tells drivers to proceed with caution. That fits slowing down rather than stopping. A flashing red light is the one treated like a stop sign, so stopping is not the rule for flashing yellow. Caution means staying ready for hazards; it does not mean hurrying through.
Why the other answers are wrong
- A. Stop and look for other vehicles, then go if there is no traffic. — A flashing yellow light does not call for a stop and look; the handbook treats a flashing red light like a stop sign, not a flashing yellow light.
- B. Stop and wait for a green light. — You are not meant to stop and wait for a green light at a flashing yellow signal; the handbook says to proceed with caution.
- C. Speed up to clear the intersection quickly. — Speeding up to clear the intersection goes against the handbook's instruction to proceed with caution at these warning locations.
Remember it
Flashing yellow: ease off the gas and keep your eyes open.
