I was cited for failure to stop one foggy night. The road had no paint. The "STOP" sign was partially eclipsed by some foliage. We get tule fog in winter, so the fog is dense with visibility sometimes <100 feet.
I returned to the scene of the crime the following night when it was foggy and took some photographs of the road and the STOP sign.
When I went to court the judge asked me, "how do you plead: not guilty, guilty, or guilty with an explanation." I pled "guilty with an explanation." I provided my photographs and the weather report from the newspaper for the night of my infraction. The officer sat silent until the judge asked for his story. The officer "did not remember the weather conditions" and could not recall if there was road paint or not, nor the partially hidden stop sign.
The judge dismissed my citation, and apologized for my receiving a ticket with such sketchy evidence. He also invited the citing officer into chambers......
