Quick answer: DWI arrestees go to the Hays County Jail in San Marcos, are held until sober, then magistrated — a judge sets the bond amount and conditions, usually within 24 to 48 hours of arrest. Release follows by personal bond, bondsman, or cash, and the conditions attached at magistration shape the months ahead.
The process is standard: booking, the sobering hold, then magistration where the charge is read and bond is set. For DWI, conditions can include no-alcohol requirements, testing, and an ignition interlock — near-automatic for BAC 0.15+ allegations or repeat charges. Hays County magistrates see a constant stream of corridor arrests, so the process itself moves briskly.
Use the first 48 hours well. Getting out matters, but so does what you get out under: workable conditions, a preserved evidence trail, and the ALR clock already being managed. Counsel engaged at this stage influences all three — and evidence like body-cam footage is easiest to preserve when requested immediately.

How long until I see a magistrate in Hays County?
Typically within 24 to 48 hours of arrest, including the sobering-up period. Weekend and holiday arrests — the corridor’s peak times — can stretch toward the longer end.
Can someone bond me out before magistration?
No — the bond amount has to be set by the magistrate first. After that, release can move quickly by personal bond, a bondsman’s surety bond, or cash posted with the county.
