What does a flashing yellow light indicate?

A flashing yellow light indicates that drivers should proceed with caution. This signal is used to alert drivers to a potential hazard or change in the driving environment, such as an intersection where they should remain vigilant for pedestrians, cyclists, or other vehicles that may be crossing their path. It does not require a complete stop, but rather encourages drivers to reduce their speed and be prepared to react appropriately to any unforeseen circumstances.

In contrast, a complete stop, indicated by a solid red light or sign, would require a driver to halt their vehicle entirely. Driving straight through at full speed would be unsafe and contrary to traffic regulations, as it fails to acknowledge potential hazards indicated by the flashing yellow. While obeying the posted speed limit is essential, it doesn't specifically convey the message of caution that the flashing yellow light represents. Thus, interpreting the flashing yellow light as a directive to proceed with caution aligns with traffic safety practices and compliance with traffic signals.
