19.3.6 Double Yellow Flags
Description: Two (2) solid motionless yellow flags, displayed at every manned flag
station around the course.
Uses: NO PASSING is permitted. This is used to indicate “a full course yellow.” This
means that there might be a problem somewhere on the track. Drivers are NOT
required to significantly slow their vehicles, however they should be prepared to
encounter a “local Yellow Flag” situation and/or a Pace Car (or a very slow moving pack
behind the Pace Car). The displaying of Double Yellow Flags does not guarantee the
appearance of a Pace Car. It is a command that NO PASSING IS ALLOWED until the
Pace Car has pulled off the course (if applicable) and the driver has passed next
manned flag station that is not displaying any Yellow Flag(s).
