What does a flashing yellow light indicate?

Answer: A — Proceed with caution

A flashing yellow light indicates that drivers should proceed with caution. This traffic signal serves as a warning to alert motorists that they need to be mindful of their surroundings, as there may be potential hazards or changes in traffic conditions ahead. Unlike a solid yellow light, which signals that the light is about to change to red and typically requires drivers to stop if it is safe to do so, the flashing yellow light does not require a complete stop. It suggests that drivers continue moving but to do so with increased vigilance and readiness to react to any developments, such as pedestrians or other vehicles. The other choices do not accurately reflect the meaning of a flashing yellow light, as it does not instruct drivers to stop or yield in a mandatory sense. Rather, it emphasizes caution and awareness while allowing continued movement through the intersection or area.
