What does a flashing red traffic light mean?

A flashing red traffic light indicates that a driver must stop completely at the intersection or the designated stopping point. After coming to a complete stop, the driver should proceed with caution when it is safe to do so, similar to the rules governing a stop sign. This signal is essential for ensuring that drivers remain aware of their surroundings and for managing the flow of traffic at intersections where the right-of-way must be observed.

In contrast, while the other options include elements of caution or stopping, they do not fully convey the requirement to stop first before proceeding, which is the primary instruction associated with a flashing red light. The emphasis on stopping ensures that drivers are giving proper attention to other vehicles and pedestrians that might be crossing their path before moving forward.
