A flashing yellow light means what?

A flashing yellow light indicates that drivers should proceed with caution. This signal is used to warn drivers that they need to be careful and be prepared to yield to any oncoming traffic or pedestrians. It serves as a reminder that there may be a hidden danger or a more complex situation ahead, such as a pedestrian crossing or heavy traffic.

In contrast to a solid yellow light, which cautions drivers to prepare to stop, the flashing yellow light means it's safe to continue but with increased vigilance. This is critical for maintaining road safety, as it encourages drivers to lower their speed and be more aware of their surroundings. It does not mean to stop immediately, which would be unnecessary and could lead to confusion or accidents, nor does it indicate that one should speed up, as doing so would compromise safety in the potential presence of hazards.
