A flashing yellow light should be treated as what?

Answer: A — caution

A flashing yellow light should be treated as a cautionary signal, indicating that drivers should slow down and proceed with caution. A flashing yellow light does not indicate a complete stop, as a stop sign would, or require yielding to other vehicles, as a yield sign would. However, if a driver is faced with a flashing yellow light at an intersection with another road, they should yield to any oncoming traffic or pedestrians before proceeding. Therefore, options B, C, and D are incorrect because they do not accurately describe the proper response to a flashing yellow light.
