What does a flashing yellow traffic light indicate?

A flashing yellow traffic light serves as a warning to drivers to proceed with caution. This light indicates that the driver should be alert and prepared to stop if necessary due to potential hazards or changes in traffic conditions ahead. It suggests that while it is safe to continue driving, extra care should be taken, particularly in areas where pedestrians or other vehicles may be present.

In contrast, a solid yellow light means that a red light is about to appear, which requires drivers to stop if they are able to do so safely. The option indicating stopping immediately is incorrect because it misinterprets the signal's intention. The right of way is not implied by a flashing yellow, as it does not specify that other vehicles or pedestrians do not have a right to cross. Lastly, traffic is not prohibited when encountering a flashing yellow light; instead, it encourages caution while maintaining the flow of traffic.
