What do flashing yellow lights at an intersection indicate?

Flashing yellow lights at an intersection indicate that drivers should proceed with caution. This signal warns that the driver needs to be alert, as conditions may require them to yield or stop, but it does not mean they must stop completely. The presence of flashing yellow lights typically suggests that there may be a potential hazard or that the intersection may require extra attention due to the possibility of cross traffic or pedestrians. Therefore, drivers must reduce their speed and remain vigilant as they navigate through the intersection.

In contrast, other signals such as solid yellow lights or stop signs would indicate the need for a complete stop or yielding instructions. Flashing yellow lights are specifically designed to convey the message of caution without implying that the driver must stop.
