What does it mean if a traffic signal is flashing yellow?

When a traffic signal is flashing yellow, it indicates that drivers should proceed with caution. This signal alerts motorists that they need to be attentive and prepared to react to any potential hazards or changes in the traffic situation. The flashing yellow suggests that while it is safe to continue driving through the intersection, drivers should reduce their speed and be vigilant, as there may be other vehicles or pedestrians present that could affect their path.

The other choices do not accurately reflect the meaning of a flashing yellow signal. A complete stop is not required, nor is there a focus solely on yielding to pedestrians; though drivers should always be mindful of pedestrian presence in any situation. Thus, the correct interpretation of a flashing yellow light as "Proceed with caution" is essential for safe driving and understanding traffic signals.
