What action should be taken when a driver sees a flashing yellow traffic signal?

When a driver sees a flashing yellow traffic signal, the appropriate action is to slow down and proceed with caution. A flashing yellow light serves as a warning that the driver should be alert and prepared to yield to any oncoming traffic or pedestrians. This signal indicates that the driver should enter the intersection with care, as there could be other vehicles or potential hazards present. It is important for drivers to remain vigilant and ready to react to any sudden changes in traffic conditions.

In contrast, coming to a complete stop immediately, as suggested by one of the options, is unnecessary unless it is required for safety or if there is other signage indicating such. Speeding up to clear the intersection can lead to dangerous situations, especially if other vehicles are present or if visibility is limited. Ignoring the signal poses significant risks, as it disregards the warning that there may be other traffic or pedestrians that could cause an accident. Overall, slowing down and proceeding cautiously ensures safer navigation through intersections when encountering a flashing yellow light.
