How Hays County Courts Handle DWI Cases

Hays County is in a period of rapid transformation — in population, in its court system, and in its approach to DWI prosecution. San Marcos has always been the county seat, anchored by Texas State University and the Interstate 35 corridor connecting Austin to San Antonio. But Buda and Kyle have exploded with suburban growth over the past decade, bringing new bar districts, restaurants, and entertainment venues into a county whose law enforcement infrastructure is still scaling to match the demand.

What that means practically is that Hays County DWI cases have a distinct character. You will encounter Texas State University students facing DWI and DUI charges, many of them first-time offenders navigating a criminal process they have never seen before. You will encounter DPS enforcement on one of the most heavily patrolled stretches of highway in Texas — I-35 between Austin and San Antonio. And you will encounter a DA’s office whose prosecutorial culture is evolving as the county’s case volume grows.

Hays County courts are accessible and relatively straightforward in their process, but “relatively straightforward” does not mean lenient. A DWI conviction in Hays County carries the same collateral consequences — loss of driving privileges, employment impact, insurance effects — as a conviction anywhere else in Texas. The county’s growing size means its prosecutors are developing the same institutional sophistication that larger counties have had for years. The time to address a Hays County DWI arrest with serious legal defense is now, not after the case has run its course.

The Courts

Misdemeanor DWI (Class A and Class B)

Misdemeanor DWI cases in Hays County are handled by the three County Courts at Law in San Marcos. These courts operate on a growing but manageable docket. The judges here are attentive to motion practice and will engage seriously with suppression arguments when they are well-supported. Hays County misdemeanor DWI cases have traditionally moved somewhat faster than Travis County cases, reflecting the smaller overall docket volume — though that gap is narrowing as the county grows.

Felony DWI (Third Degree and Above)

Felony DWI matters — a third or subsequent offense, intoxication assault, or intoxication manslaughter — are handled by Hays County’s four district courts. These courts have seen an increase in felony DWI matters as the county has grown and as repeat offenders from the growing suburban areas appear with more frequency.

The Docket

Hays County misdemeanor DWI cases typically resolve in nine to twenty-four months. The timeline variance reflects the difference between straightforward cases that move toward negotiated resolution and contested matters involving suppression hearings, blood analysis disputes, or cases that proceed to jury trial. Felony cases run longer, with most resolving in twelve to thirty-six months.

• Arrest → booking at Hays County Jail, San Marcos → magistration, bond set
• ALR hearing request — file within 15 days; Hays County cases coordinated through Austin-area DPS ALR offices
• First court appearance — arraignment in County Court at Law, charges formally read, plea entered (typically not guilty initially)
• Discovery — dashcam/body cam footage, HGN and FST video, blood or breath results, officer notes, arrest report
• Pretrial motions — suppression hearings on stop legality, SFT administration, blood draw warrant validity, DPS trooper trooper credentialing challenges
• Plea negotiations or trial setting — cases with compromised evidence are better negotiating positions; trial in Hays County is a viable option with proper preparation
• Resolution — plea, jury trial, or motion to dismiss

The People

The Hays County District Attorney’s Office is smaller than Travis or Bexar County, but its prosecutorial approach has grown more systematic as case volume has increased. Prosecutors in Hays County are generally accessible and willing to engage meaningfully with defense arguments, but that accessibility does not translate to automatic leniency — particularly on DWI cases involving a high BAC, prior offenses, or an accident.

One practical dimension of Hays County’s DA’s office is that prosecutors here develop substantive familiarity with the county’s recurring enforcement corridors and the officers who work them. If a Hays County DPS trooper makes a procedural error on a stop — and those errors do happen on the I-35 corridor — the prosecutors in San Marcos know that trooper’s history and how their documentation typically looks. Defense attorneys who know the same things operate in this courthouse on equal footing.

Local Considerations

I-35 Enforcement Corridor

The stretch of Interstate 35 running through Hays County — from the Travis County line south through Buda, Kyle, San Marcos, and toward the Comal County line — is one of the most heavily patrolled DWI enforcement corridors in Texas. DPS troopers are consistently active on this stretch, particularly on weekend nights and around Texas State University event calendars. Hwy 290 West, serving the Wimberley area and the wine country, is a secondary enforcement corridor that generates arrests that often differ in character from the I-35 interstate stops.

Texas State University — Student Cases

A substantial portion of Hays County’s DWI and DUI (under 21) caseload involves Texas State University students. These cases have a distinct character: most involve first-time offenders who have no prior criminal history, are typically not hardened criminal defendants, and face consequences that can affect their academic career and professional future in ways that extend well beyond the criminal case itself.

Students facing DWI charges in Hays County also face a parallel university conduct process through Texas State. The criminal case and the university conduct case are independent proceedings, but what happens in one can affect strategy in the other. Our team is experienced in coordinating criminal defense strategy with university conduct considerations — a nuance that matters specifically in the San Marcos context.

No-Refusal Periods — Targeted, Not Year-Round

Unlike Travis and Williamson Counties, Hays County’s no-refusal enforcement is periodic rather than year-round. Blood warrant sweeps occur during major holiday periods and targeted enforcement weekends. Outside of those periods, a refusal may not automatically result in a blood warrant — though it can and does happen, particularly when a DPS trooper has grounds to pursue one. Understanding whether a specific arrest occurred during a no-refusal period is relevant to the blood evidence analysis in any Hays County case.

Buda and Kyle Growth — New Bar Corridors

The Burleson Road corridor in Buda and the Kyle Parkway area in Kyle have developed active bar and restaurant scenes as the suburbs have grown. DWI arrests in these areas involve municipal police departments (Kyle Police, Buda Police) rather than DPS troopers, and the documentation, camera systems, and procedural patterns differ from highway patrol stops. These municipal arrests are still adjudicated in Hays County courts, but the underlying enforcement mechanics are different enough to require separate review.

How We Approach Hays County Cases

For Texas State University students, we bring an approach that treats the university conduct process as part of the overall defense picture — not an afterthought. What you say, when you say it, and how your criminal case is resolved all have implications for university disciplinary proceedings, and we coordinate those considerations from the beginning.

We handle both the criminal DWI defense and the ALR license hearing in Hays County. The ALR process in a DPS trooper case is particularly important because the trooper’s stop documentation and observation notes become accessible through ALR discovery — giving us a preview of the evidence before we are fully engaged in the criminal case. We use that preview.
