What does a flashing yellow light indicate to drivers?

A flashing yellow light signals to drivers that they should proceed with caution. This warning indicates that there may be potential hazards ahead or that the situation requires increased attention. Drivers are expected to maintain their speed but to be prepared for any changes in traffic conditions or to yield to pedestrians or other vehicles if necessary. This is crucial for ensuring safety in areas where the risks may vary, such as near schools, construction zones, or intersections.

The other options suggest actions that do not align with the intended message of a flashing yellow light. Stopping or preparing to stop would be appropriate if the light were red or some other warning signal, but a flashing yellow does not compel drivers to stop unless circumstances require it. Rushing to speed up is also dangerous, as it contradicts the cautionary intent of the signal and can lead to accidents. Thus, the correct interpretation directs drivers to be vigilant and mindful of their surroundings while continuing to drive.
