What does a flashing yellow light signify for drivers?

A flashing yellow light is a signal that indicates drivers should proceed with caution. This means that while it is safe to continue driving, the driver must remain alert and be prepared to react to any potential hazards or changing conditions. The flashing yellow light serves as a warning that something may require special attention, such as an intersection, a pedestrian crossing, or roadwork.

In contrast, the other choices suggest actions that are either overly aggressive or inappropriate for the situation. Proceeding at full speed would ignore the cautionary nature of the flashing light, potentially leading to unsafe driving practices. Waiting for it to turn green or stopping and yielding do not align with the purpose of a flashing yellow light, as this indication does not imply that the driver must stop or that there is a stop signal. Instead, it encourages a careful but forward motion, prioritizing safety on the road.
