What does a flashing yellow signal light indicate?

A flashing yellow signal light is a warning signal that indicates drivers should be alert and exercise caution. It specifically advises motorists to slow down and proceed with care through the intersection or area where the light is displayed. This signal is often used in situations where there may be increased pedestrian activity, road work, or an intersection that does not have a higher level of traffic control.

In contrast to a solid yellow light, where the expectation is to prepare to stop, a flashing yellow light allows for continued movement while encouraging vigilance. It alerts drivers to potential hazards or changes in road conditions, ensuring they make safe decisions as they navigate.
