What does a flashing yellow traffic light mean?

A flashing yellow traffic light indicates that drivers should proceed with caution. This signal serves as a warning that there may be potential hazards or that conditions require extra attention. For instance, when approaching a flashing yellow light, drivers should slow down and be prepared to stop if necessary, particularly at intersections where other vehicles may also be crossing.

In contrast, a solid yellow light generally warns that the light is about to turn red, prompting a stop if it is safe to do so. A flashing yellow light does not require stopping but rather encourages vigilance and careful driving. This guidance is crucial for maintaining safety on the road, as it helps ensure that drivers remain alert to changing conditions.
