Speeding 15-20 over (the last time traffic where I live didn't do that was the last rush hour before the lockdown) is a civil violation or misdemeanor at the discretion of the officer.
In my jurisdiction smoking within a certain distance of certain government facilities (including the nondescript leased office that the registrar of deeds for my county is in, if the sign is to be beloved) is a misdemeanor (punishable by like a $50 fine or up to one night in jail IIRC).
I know for a fact that not getting certain kinds of municipal permits can be prosecuted as a misdemeanor around here and pretty much nobody gets permits for anything if the property is their primary residence (and the inspectors don't care).
Driving traffic speed on a highway is usually a misdemeanor unless you live somewhere with reality-based speed limits.
