What is indicated by a flashing yellow traffic light?

A flashing yellow traffic light serves as a warning signal for drivers. It indicates that they should proceed with caution through the intersection or the area where the light is displayed. The presence of the flashing yellow light suggests that there may be potential hazards that require a driver to be vigilant and prepared to react as necessary.

This signal does not require a complete stop like a red light would; rather, it instructs drivers to be aware of their surroundings and to navigate through the intersection safely while maintaining a reasonable speed. The caution is advised because there may be pedestrians, cyclists, or other vehicles that could pose a risk.

In contrast to this, stopping for a red light or yielding to all traffic (which would be necessary at a stop sign) is not the expectation set forth by a flashing yellow. Speeding up to clear the intersection is also not appropriate and could lead to dangerous situations.
