I have a similar concern, I got a jaywalking ticket when I was 16 at my high school. I have barely any memory of it but I do remember having to go to court and plead guilty and pay a fine. Does that fact that I went to court mean that it was in fact a misdemeanor? This was in california around ~2009 or 2010. I spent $5 to search local court records and didn't find anything with my name on it, but as I have seen before, this doesn't mean it won't show up in a background check.
