Crime and Punishment - The Double Yellow

[Al Fernandez]

Exactly, a single yellow and double yellow have completely different restart rules.
Had this been a single yellow situation at T13 and a checker at S/F, it would have been game on racing.
With a double yellow, the restart is at the green flag or at the next station not displaying a yellow. Since S/F had a checker flag the race is over since the racing wouldn't have been able to resume until After the station. Any racing prior to S/F was prohibited.

Somewhat different in that they both have an exception. The baseline for both single and double yellow is the same: no passing until past the next station not displaying a yellow. For single yellow situations, the exception is that you may resume racing when past the incident. For double yellows, the exception is you can resume racing before start/finish if you see a green at start/finish. That is an actual green flag, not a "no yellow therefore its green" green.
