Here’s a fun little law from 1903 that prohibits spitting in public.
Section 147:18 Expectoration. –
It shall be unlawful for any person to spit upon any sidewalk, in the compact part of any city, village or town, or in any railway station, hall or other public place, or in any street or steam railway car other than smoking cars, except into spittoons or other receptacles provided for that purpose.
While impolite, spitting outside and away from others is no danger to anyone. Actually spitting on someone is already covered under assault/battery laws. This is yet another law that goes largely unenforced, only to be dusted off occasionally when cops need a reason to charge someone they don’t like.
