What does a flashing red traffic light indicate?

A flashing red traffic light signals that drivers must come to a complete stop, just as they would at a stop sign. This indication is crucial for ensuring safety at intersections or areas where traffic flow may be disrupted. After stopping, drivers are required to check for any oncoming or cross traffic, and may only proceed when it is safe to do so. This rule helps prevent accidents and allows all road users to have a clear understanding of their right-of-way.

The other responses do not accurately reflect the required actions at a flashing red light. Proceeding with caution without stopping would compromise safety, and yielding to all oncoming traffic does not convey the necessity to stop first. Additionally, the notion of intersections with no traffic allowed is misleading, as flashing red lights do not restrict traffic from entirely crossing the intersection but rather mandate a stop before allowing movement when it's safe.
