What does a flashing yellow light mean?

A flashing yellow light indicates that drivers should proceed with caution. This signal serves as a warning that something, such as a pedestrian crossing or an intersection ahead, requires attention. It alerts drivers to reduce their speed and be prepared to stop if necessary. Unlike a solid yellow light, which advises caution before making a decision to stop, the flashing yellow light clearly indicates that it is safe to continue driving but with heightened awareness of the surroundings.

The other choices suggest actions that are not appropriate in response to a flashing yellow light. Stopping immediately or yielding to all traffic does not align with the meaning of the signal, as it does not indicate a complete halt is necessary. Speeding up to clear the intersection is also not advisable as it contradicts the caution required when encountering such a signal.
