What does a flashing red light at an intersection indicate?

A flashing red light at an intersection indicates that drivers must treat it as a stop sign. This means you must come to a complete stop before proceeding. After stopping, you then have the right to proceed with caution, ensuring that it is safe to do so, especially by yielding to any oncoming traffic or pedestrians that may have the right of way.

The requirement to stop completely first means that simply approaching with caution, as suggested by the first choice, would not satisfy the legal requirement set by traffic laws for a flashing red light. The other options also misinterpret the action required – yielding to traffic does not apply in this case, as it is about stopping first, and turning around is not relevant at an intersection governed by such a signal.
