What does a flashing red traffic light indicate?

A flashing red traffic light signals drivers to come to a complete stop at the intersection, similar to a stop sign. After stopping, the driver must yield to any oncoming traffic or pedestrians. Once it is safe to do so, the driver may proceed through the intersection. This rule ensures safety as it allows drivers to assess their surroundings before continuing.

The other options do not accurately reflect the meaning of a flashing red light. Proceeding without stopping is not permitted, as is the case with a regular red light. Slowing down before turning does not align with the requirement to stop completely, and preparing for an immediate turn lacks the necessary emphasis on assessing traffic conditions first. The flashing red light is specifically designed to ensure that drivers take the appropriate precaution of stopping before proceeding.
