What does a flashing yellow light mean?

A flashing yellow light indicates that drivers should proceed with caution. This signal warns you that there may be potential hazards ahead, such as a pedestrian crossing or a situation where the normal traffic rules may need to be adjusted. It serves as an alert to remain vigilant and be prepared to react appropriately to whatever may be unfolding on the road, whether that means slowing down or being attentive to any changes in traffic flow.

In contrast, a solid yellow light typically suggests that the light will soon turn red, requiring drivers to be prepared to stop, which differs from the caution indicated by a flashing yellow. The other choices imply actions that are more definitive, such as stopping immediately or yielding to pedestrians; however, those actions do not align with the purpose of a flashing yellow light, which emphasizes caution rather than a mandatory action.
