John Smith XX:
but would the person at least get arrested?
If you mean put in handcuffs and shoved into the back seat of a police car, probably not.
Minor offenses like that usually involve an on scene interview and then the suspect is sent on his way.
The police then file the report and it's up to the prosecutor as to what happens next.
Even if charges were filed it would be likely that only a citation and summons would be issued and served or sent to the suspect.
