Jail is a terrible place and I wouldn't wish it upon anybody.
But unfortunately, it is a part of the criminal justice process. If you are issued a Promise to Appear (PTA) for a misdemeanor or criminal traffic offense, then you do not need to worry about being booked into jail.
However, if you are charged with a felony, picked up on a bench warrant, or taken into custody for a misdemeanor offense, you will have to go to jail and go through the booking process.
Whether Miami-Dade, Broward, or Palm Beach; the booking process takes a long time. Several hours, perhaps even a full day. But if you are held for first appearance judge (many serious felonies and all domestic violence cases) you will likely have to spend the night in jail and see the judge the next day for a bond determination.
Once you are booked, you may be able to post a bond provided your case is a bondable offense. If a bond amount is set - either by the first appearance judge or simply based on the charge (also called a convenience bond) - you will likely be released many hours after the bond is posted.
If you have any out-of-county warrants, you will not be able to be released, even if you post a bond. Corrections will always run you for warrants prior to processing your release.
The booking and bond process can take, in total, up to 24 hours or longer. If you are released on Pretrial Services or House Arrest, it could take even longer.
