What does a flashing yellow light indicate?

A flashing yellow light is a signal that indicates drivers should proceed with caution. This type of signal is used to warn drivers that there may be hazards ahead, and they need to be prepared to slow down or take precautions as necessary. It typically indicates that the intersection or area may require increased attention, such as school zones or construction areas, where conditions are not ideal.

In contrast, a steady yellow light usually means that a traffic signal is about to change to red, prompting drivers to stop if it is safe to do so. The other choices would misinterpret the intention of a flashing yellow light; stopping immediately, yielding to all traffic, or increasing speed does not align with the cautionary guidance that the flashing yellow light is meant to convey.
