What does a flashing yellow traffic signal mean?

A flashing yellow traffic signal indicates that drivers should proceed with caution. This signal is typically used in situations where the traffic conditions may require extra alertness, such as at intersections or pedestrian crossings. It serves as a warning that the driver should be prepared to stop if necessary, but they are not required to stop unless it is safe to do so.

The emphasis is on exercising caution and being aware of their surroundings, especially as there may be pedestrians, other vehicles, or obstacles that could require the driver to slow down or come to a complete stop. This understanding is crucial for maintaining safety on the road and ensuring that the driver is prepared for any potential hazards.
