What does a flashing yellow traffic light signify?

A flashing yellow traffic light signifies that drivers should proceed with caution. This signal is used to alert motorists that they need to be aware of potential hazards or changes in traffic conditions ahead. When approaching a flashing yellow light, drivers should reduce their speed and remain alert, as there may be pedestrians, cyclists, or other vehicles that require additional attention.

The flashing yellow is distinct from a solid yellow light, which typically indicates that a traffic signal is about to change to red, requiring drivers to prepare to stop. The emphasis on caution rather than a complete stop allows for the flow of traffic while still ensuring safety. This versatile traffic control device helps improve traffic efficiency without compromising safety, as it encourages drivers to pay closer attention to their surroundings.
