What does a flashing yellow traffic signal mean?

Answer: C — Proceed with caution

A flashing yellow traffic signal indicates that drivers should proceed with caution. This alert serves to warn motorists that they are approaching a potentially hazardous situation, such as an intersection where other vehicles or pedestrians may be present. The flashing yellow light does not require a complete stop but prompts vigilance. It is essential for drivers to assess the roadway and any surrounding traffic before continuing through the intersection. This signal specifically suggests that safety and awareness are key; drivers must be ready to react to any unexpected conditions. In contrast, a solid yellow light, which might be confused with the flashing yellow, implies that a driver should prepare to stop unless it's unsafe to do so. Other options presented do not align with the meaning of a flashing yellow light, as they imply a more definitive action than merely proceeding with caution.
