What does a flashing yellow traffic light mean?

A flashing yellow traffic light signifies that drivers should proceed with caution. This means that while there is no requirement to stop, drivers need to be alert and prepared to yield to other vehicles or pedestrians that may be present in the intersection. It serves as a warning that conditions ahead may require extra attention, such as a pedestrian crossing or a potentially hazardous intersection.

In contrast, the other options suggest actions that would be unsafe or impractical under such circumstances. Stopping immediately or coming to a complete stop is unnecessary and could lead to confusion or accidents, as the signal does not indicate a stop is needed. Speeding up to rush through the intersection would also increase the risk of an accident, as it disregards the need for caution in the area. Therefore, the correct interpretation of a flashing yellow light is to proceed with caution while remaining aware of your surroundings.
