If you see a flashing red light, what is the best course of action?

When encountering a flashing red light, the best course of action is to stop and yield. A flashing red light typically indicates that there is a need for caution, similar to a stop sign at a controlled intersection. It signals that drivers should prepare to stop and yield to any traffic or pedestrians in the area before proceeding. This ensures safety for all parties involved, as disregarding the flashing warning can lead to accidents or hazardous situations.

The other options may suggest actions that could compromise safety. Accelerating through an area with a flashing red light would ignore the warning and could lead to dangerous outcomes. Continuing without stopping also dismisses the need for caution indicated by the light. Lastly, stating that caution is not required contradicts the essential nature of traffic control devices, which are designed to manage safety on the road.
