What does a flashing yellow traffic light indicate?

A flashing yellow traffic light indicates that drivers should slow down and prepare to stop. This signal is used to alert drivers of a potentially hazardous condition or to indicate that they are approaching an intersection where they may need to yield to cross traffic or pedestrians. It serves as a warning that while they are not required to stop, they should be vigilant and ready to stop if necessary.

This is particularly important in intersection situations where other vehicles may not be yielding or where visibility is compromised. The intention behind the flashing yellow is to promote caution rather than to encourage an immediate stop or disregard for the traffic conditions, hence signaling drivers to reduce speed and stay alert about their surroundings.
