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. See 19.3 and 20.12.1
