You can absolutely go to jail for violating an injunction – this only applies to respondents, however. Violating an injunction is a first-degree misdemeanor offense and you can go to jail, be put on probation, or a combination of the two (for up to one year) if you violate an injunction.
Examples of violating an injunction would be refusing to leave a shared residence, refusing to surrender firearms, destroying property belonging to the other person, contacting the other person, and so on. Accidentally running into the other person in a public place (like Publix) is not a violation.
If you are the petitioner, you cannot go to jail for dismissing an injunction or failing to show up to a final hearing.
