White and Green Flag

The "White and Green Flag" is not a standard combined signal in motorsport, but rather refers to two separate flags that each have distinct meanings when displayed individually during races.

The green flag signals the start or restart of a race, indicating that the track is clear and drivers can race at full speed. It's the universal "go" signal in motorsport. The white flag typically indicates the final lap of a race in American racing series like NASCAR and IndyCar, though in Formula 1 and some other series, it warns drivers of a slow vehicle on the track.

If you ever hear commentators mention these flags together, they're likely referring to separate flag conditions rather than a combined signal. Understanding these basic flag signals is essential for following race communications and safety protocols.
