What does a flashing yellow traffic signal mean?

A flashing yellow traffic signal indicates that drivers should proceed with caution. This means that while they are not required to stop, they should be aware of their surroundings and be prepared for any potential hazards. It serves as a warning that there are changes in the traffic environment ahead, such as an intersection, pedestrian crossing, or construction zone.

In this scenario, caution is advised because other vehicles or pedestrians may be present or there may be other conditions that require drivers to be alert. It communicates that while travel is permitted, vigilance is essential to ensure safety. Unlike a solid green light, which allows full speed and movement without concern, the flashing yellow encourages a more careful approach.
