How should a driver react to a flashing yellow traffic signal?

A flashing yellow traffic signal indicates that a driver should proceed with caution. This type of signal is used to alert drivers to a situation that requires them to be vigilant but does not require them to stop completely. By reacting cautiously, drivers can safely assess their surroundings for other vehicles, pedestrians, or any potential hazards that may be present in the intersection. This reinforces the need for awareness and careful navigation through the intersection while allowing for continued movement, as opposed to a full stop.

In contrast, speeding up through the intersection is unsafe as it does not take into account the need to be vigilant. Coming to a complete stop would be unnecessary and could disrupt the flow of traffic. Ignoring the signal altogether would disregard the safety measures put in place and increase the risk of accidents. Therefore, proceeding cautiously and staying alert is the appropriate response to a flashing yellow signal.
