Seems like my post got deleted, so reposting. Either bug with forum or moderator deleted it. In response to the latest comments.
I was cited VC 21461 but citation text/notes state "failure to obey turnout", which sounds like VC 21656 to me. If not, what's the best matching VC that the citation refers to? Googling up the signs referenced here, where I was driving I had seen signs which I believe to be R4-13.
along the stretch fo Hwy 20 I was driving, only saw a short right lane for once or twice. The whole time it was mainly (small/tiny) turnouts, which also were unpaved, and dipped below the paved road a bit that required careful turning into if you didn't want to go rough brake/stop into them while traveling at decent normal (fast) speed.
The citation noted the area as being SR 20 MPM 23.
