What is the meaning of double waved yellow flags?

The meaning of double waved yellow flags is to indicate a significant hazard on the track that necessitates caution among drivers. When drivers see double waved yellow flags, they must understand that overtaking is strictly prohibited, and they should reduce their speed. This flag signals that there is a serious situation ahead, such as an accident or a major obstacle that could pose a risk to safety. The presence of the double yellow flags means that participants need to be vigilant and prepared for potential changes in track conditions.

This differs from other flags; for instance, normal racing conditions would not call for yellow flags, and the end of a session is indicated by a different flag. The instruction to return to the pit lane immediately is also signified by other flags or signals, not by double waved yellow flags, which specifically focus on hazards within the racing environment.
