What does a flashing red traffic signal mean?

A flashing red traffic signal indicates that drivers must come to a complete stop, just as they would for a stop sign. After stopping, they are required to yield the right-of-way to any pedestrians and other vehicles that may be in the intersection or approaching. Once it is safe to do so, drivers can proceed through the intersection. This signal is used to alert drivers to exercise caution and ensure safe passage through potentially hazardous areas, similar to a stop sign where full attention is required before moving forward.

In contrast, options that suggest slowing down or yielding do not convey the immediate necessity of stopping, which is essential for the correct response to a flashing red signal. The mention of emergency vehicles, while important in traffic law, does not directly correlate with the implications of a flashing red light, which applies universally to all vehicles regardless of their nature.
