Which signal allows an operator to proceed with caution through an intersection?

The flashing yellow signal is designed to alert drivers to proceed through an intersection with caution. It indicates that while it is safe to continue, drivers should be more aware of the surroundings and be prepared to stop if necessary. The flashing yellow signal is different from a steady green, which means go but doesn’t emphasize caution, and a steady yellow signal, which typically warns drivers that a light is about to change to red, advising them to prepare to stop. A flashing red light requires a complete stop and can be treated like a stop sign, allowing no movement without yielding to other traffic. Thus, the flashing yellow is the correct signal for allowing cautious movement through an intersection.
