What does a flashing red light at an intersection mean?

A flashing red light at an intersection indicates that drivers must make a complete stop before proceeding, similar to a stop sign. This signal serves to alert drivers that they must yield to any oncoming traffic or pedestrians before continuing through the intersection. It is important for drivers to ensure the way is clear and that it is safe to proceed after stopping.

In contrast, the other options suggest actions that do not accurately reflect the requirement of a flashing red light. Simply going if the way is clear implies a less stringent approach than the complete stop that is mandated. Slowing down and continuing cautiously does not fulfill the requirement of stopping completely. Yielding to oncoming traffic signifies an incomplete understanding of the signal, as the flashing red light necessitates a full stop first, allowing for a safer determination of traffic conditions.
