A police officer in certain situations has an option of issuing a Cite and Release citation for a person to appear before a magistrate at a later date, rather than arresting someone or taking them to jail for some misdemeanors. This avoids an immediate arrest by a police officer, which also avoids other issues like towing of your vehicle, custody of minor children, and being transported in a police vehicle.

What do I do if I am given a Cite and Release citation?
On your appearance date, you will report to the Hays County Jail located at 1307 Uhland Road, San Marcos TX 78666. You will appear at the Jail Lobby by 8:00 AM and inform the staff you are present. Later all persons appearing that day will be taken to an area where you can be photographed and fingerprinted. Afterwards you will be taken to the conference room to wait for the Magistrate Judge.
