What does a flashing red traffic light indicate?

A flashing red traffic light signals drivers to come to a complete stop, just like a stop sign. After stopping, the driver must yield to any oncoming traffic or pedestrians before proceeding. This means the driver can only continue through the intersection when it is safe to do so—ensuring that they do not interfere with other vehicles or pedestrians who may have the right of way.

The other options might share some elements that could be misleading. For instance, while a flashing red does indicate a need for caution, it does not imply that the driver should wait indefinitely (as suggested in the first choice); instead, it requires an active assessment of the situation before proceeding. The second choice incorrectly suggests that a flashing red indicates an impending solid red light, which is not how traffic signal phases typically operate. Lastly, a flashing red does not indicate that the street ahead is closed; rather, it signifies the need to stop and evaluate the traffic conditions.
