What does a flashing red traffic light mean?

A flashing red traffic light indicates that drivers must come to a complete stop. This signal functions similarly to a stop sign; it requires drivers to clearly assess the intersection for any oncoming traffic, pedestrians, or other hazards before proceeding. Once it is safe to continue, drivers may then proceed through the intersection with caution.

In contrast, the other options imply different actions that do not align with the requirement of a flashing red light. For example, slowing down and proceeding with caution could lead to unsafe situations, as it suggests that drivers can move through the intersection without fully stopping. Likewise, speeding up to clear the intersection contradicts the need for a complete stop and increases the risk of accidents. Yielding to oncoming traffic only is not applicable here, as the flashing red light necessitates that all vehicles stop regardless of other traffic signals or conditions.
