What does it indicate if a traffic signal is flashing yellow?

When a traffic signal is flashing yellow, it signifies that drivers should proceed with caution. This means that while vehicles are permitted to continue moving, they must be vigilant and prepared for any potential hazards. The flashing yellow light serves as a warning that conditions may require careful attention, such as the presence of pedestrians, other vehicles, or road conditions that may not be immediately apparent.

The intention behind this signal is to alert drivers to be more aware as they approach the intersection or area controlled by the flashing light, rather than coming to a complete stop or yielding as they would at other traffic signals. This clear directive helps maintain the flow of traffic while ensuring safety, allowing drivers to navigate through the area with due diligence.
