What does it mean if a traffic light is flashing yellow?

When a traffic light is flashing yellow, it indicates that drivers should proceed with caution. This signal warns that there may be a hazard or that the intersection requires careful attention, but it does not require a complete stop like a red light would. Drivers should reduce their speed and be alert for any potential dangers, such as pedestrians crossing or vehicles that may not be following the traffic rules properly.

In contrast, a complete stop is necessary for a red light or a stop sign, while preparing to stop immediately would apply when a light is transitioning from green to red. Ignoring the signal is never advisable, as it poses risks to all road users and could lead to collisions or legal penalties. Therefore, understanding the meaning of a flashing yellow light is crucial for safe navigation of roadways.
