What does a flashing yellow light at an intersection indicate?

A flashing yellow light at an intersection signals that drivers should proceed with caution. This means that while it is not necessary to stop, it is essential to understand that there may be potential hazards ahead or that the traffic conditions require additional care. Drivers should reduce their speed and be prepared to yield to any oncoming traffic or pedestrians.

This cautionary signal alerts drivers to the fact that they should be more vigilant and watchful as they navigate through the intersection. It is an indication that everything may not be completely clear, warranting extra attention to ensure safety.

The other options do not accurately reflect the meaning of a flashing yellow light. Stopping immediately or yielding to all vehicles does not align with the purpose of the flashing yellow alert, which is about caution rather than action. Additionally, suggesting it is safe to speed through contradicts the very nature of the caution that a flashing yellow light represents.
