Too Afraid to Ask

A full course yellow means the whole race is slowed down because something on track needs attention. Everyone has to drive more carefully, and it often changes when teams decide to pit.

Technical Definition

A full course yellow is a race control decision that slows the entire field under caution conditions. Drivers must reduce speed and follow rules until the track is cleared, which can dramatically change strategy because it affects when pit stops are allowed and how safely cars can pass.
