What does a flashing yellow light indicate?

A flashing yellow light serves as a warning to drivers that they should proceed with caution. This signal indicates that there may be a potential hazard or a change in traffic conditions ahead. It is crucial for drivers to reduce their speed and be alert as they approach the area. Unlike a solid yellow light, which signals that the light is about to change to red and encourages drivers to stop, the flashing yellow does not require a full stop. Instead, it reminds drivers to remain vigilant and prepared to react to any upcoming changes, such as pedestrians crossing or other vehicles making unexpected maneuvers.

In contrast, the other options suggest actions that are not appropriate for this situation. Stopping immediately implies that there is a requirement to halt, which does not apply to a flashing yellow light. Similarly, going without stopping or changing lanes quickly does not align with the intended caution conveyed by the light. The focus of a flashing yellow signal is to promote awareness and careful navigation, ensuring safety for all road users.
