I saw this on one of Dave Moulton's blog posts. I contacted him, but haven't heard back. I've also googled it like crazy. I still can't find it.
I really like it because it shows a clear picture of the care crossing the double-yellow line to pass the cyclist. From my experience not many drivers realize this is legal. I also like that it states "it's the law" which most people don't seem to realize, and I'm lucky enough to live in a state where it is the law.
Does anyone know where I can buy this sticker?
