What does a flashing red light at an intersection mean?

Answer: B — Come to a complete stop and proceed when safe

A flashing red light at an intersection indicates that drivers must come to a complete stop, similar to a stop sign. This signal requires drivers to evaluate the intersection and only proceed when it is safe to do so, ensuring the right of way is respected for all vehicles and pedestrians. Treating a flashing red light as a stop sign enhances safety by making sure that drivers are alert and ready to navigate the intersection carefully. In contrast, other options do not accurately represent the required action for a flashing red light. Slowing down and proceeding with caution does not ensure sufficient safety, while yielding to oncoming traffic might not be necessary if a full stop is not first observed. Turning around is not typically a response to a flashing red light; rather, it is about stopping and assessing conditions to proceed safely.
