What does a flashing yellow traffic light mean?

A flashing yellow traffic light serves as a warning to drivers. It indicates that they should proceed with caution and be prepared to slow down or take appropriate action. This signal is typically used at intersections or areas that require alertness due to potential hazards. The intent is to make drivers aware that they should be vigilant and mindful of their surroundings, as there may be other vehicles, pedestrians, or obstacles nearby.

In contrast, options suggesting that a driver should stop, yield, or proceed at high speed do not align with the safety message of a flashing yellow light. Stopping would be inappropriate since the light does not indicate a full stop is necessary, and yielding implies that traffic needs to give way, which is not the case with a flashing yellow signal. Proceeding at high speed contradicts the cautionary nature of the flashing light.
