signals-markings
When a traffic signal flashes yellow, what action is required?
- Slow down and proceed with caution
- Stop and wait for a green light
- Accelerate before cross traffic enters
- Turn without checking the intersection
Answer: Slow down and proceed with caution. A flashing yellow traffic light means slow down and proceed with caution. The driver should also be prepared to stop for traffic entering the intersection. A complete stop followed by waiting for green describes neither the stated flashing-yellow instruction nor the ordinary meaning of this signal. Accelerating reduces the time available to react, and turning without checking ignores the need to watch entering traffic. Treat the yellow flash as a warning to reduce speed, scan the intersection, and keep enough control to stop if another road user appears.
