A flashing red traffic signal at an intersection means which of the following?

A flashing red traffic signal at an intersection is an indication for drivers to come to a complete stop, similar to a stop sign. The correct interpretation requires understanding that when faced with such a light, the vehicle operator must stop and then proceed only when it's safe and they have yielded the right-of-way to any other traffic or pedestrians present.

The choices suggesting either "slow down and proceed with caution" or "stop only if it is necessary to yield the right-of-way" do not align with the strict requirement of coming to a full stop. The flashing red light fundamentally communicates that all vehicles must stop before making a decision to move, ensuring safety at the intersection. Therefore, the most accurate response reflects the necessity of stopping entirely before proceeding, distinguishing it from interpretations that allow for less strict compliance.
