What does a traffic signal showing a flashing yellow light mean?

A traffic signal displaying a flashing yellow light indicates that drivers should proceed with caution. This signal warns that the intersection or the area ahead may require extra attention and that potential hazards might be present. Drivers are expected to slow down, look for oncoming traffic, and be prepared to yield to pedestrians or other vehicles that may be crossing their path.

This cautious approach helps ensure safety, as it communicates to drivers that although they can continue moving through the intersection, vigilance is necessary. In contrast, other signals such as a solid yellow light typically indicate that drivers should prepare to stop, while a steady green light allows for safe passage without the need for caution.
