If you were arrested for DWI in Houston, the next 15 days will determine the trajectory of your case — and your driving privileges. This guide walks you through exactly what happens after a first-offense DWI arrest in Harris County, what to expect at every stage of the process, and what Herman Martinez does at each step to protect your freedom, your license, and your future.
The First 24 Hours After a DWI Arrest in Houston
After a DWI arrest in Harris County, you’re transported to the Harris County Jail at 1200 Baker Street. The intake process typically takes four to eight hours — longer on weekends and holidays when the jail is at capacity.
During booking, you’ll be fingerprinted, photographed, and your personal property inventoried. If you refused the breath or blood test, or provided a sample above .08, the arresting officer gave you a DPS notice — the DIC-25 form — that starts a 40-day clock before your license is automatically suspended.
Once booked, you’re held until a magistrate sets bail (typically within 24 hours), and you or someone else posts it. For a first-offense DWI without injuries or aggravating factors, bail in Harris County typically runs $500 to $2,500. The magistrate may add conditions including no alcohol consumption or ignition interlock as a condition of release.
From the date of your arrest, you have exactly 15 calendar days to request an Administrative License Revocation (ALR) hearing with the Texas Department of Public Safety. Miss this deadline and your license is automatically suspended 40 days after your arrest — no hearing, no appeal. This is the first call Herman makes when retained on any DWI case.
Harris County’s DWI Court System: What You’re Walking Into
Harris County has one of the most active criminal court systems in the country. A first-offense DWI (Class B misdemeanor) is assigned to one of Harris County’s 16 County Courts at Law. Each court has its own docket culture and scheduling patterns — and the prosecutors who handle these cases come from the Harris County District Attorney’s dedicated DWI division.
Unlike smaller counties where DAs handle general criminal dockets, Harris County DWI prosecutors specialize. They’ve seen thousands of DWI cases. Herman has spent years in these same courts as a former prosecutor and knows exactly how the DA’s office evaluates the evidence and where cases break down in their favor.
Your First Court Appearance: The Arraignment
Your arraignment is usually scheduled within a few weeks of arrest. You formally enter a plea. For nearly every client, Herman advises pleading not guilty — even if a negotiated resolution is likely. Entering not guilty preserves all options, allows time for complete discovery review, and forces the state to produce its evidence before any deal is discussed.
First-Offense DWI Penalties in Texas (2026)
A first-offense DWI is a Class B misdemeanor. The statutory consequences:
| Consequence | Range |
|---|---|
| Jail | 72-hour minimum; up to 180 days maximum |
| Fine | Up to $2,000 (not including court costs) |
| License suspension | 90 days to 1 year |
| Annual DPS surcharges | $1,000/year × 3 years ($1,500/year if BAC was .16+) |
| DWI Education Program | Mandatory 12-hour course |
| Community supervision | Up to 2 years probation |
These are statutory consequences. For most clients, the real-world consequences — job loss, professional license action, insurance increases, immigration consequences — are far more damaging.
What Elevates a First DWI to a Felony
- BAC of .15 or above: Class A misdemeanor — up to $4,000 fine, up to 1 year in jail, mandatory ignition interlock upon any conviction
- Child passenger under 15: State jail felony (180 days to 2 years in state jail, up to $10,000 fine)
- Accident causing serious bodily injury: Intoxication Assault — 3rd degree felony (2–10 years, up to $10,000)
- Accident causing death: Intoxication Manslaughter — 2nd degree felony (2–20 years, up to $10,000)
- Open container in vehicle: Minimum 6 days jail (instead of 72 hours) if convicted
The Harris County DIVERT Program: The Best Outcome for Eligible First-Timers
The Harris County District Attorney’s Office operates the DIVERT Program (DWI Intervention and Vertical Enforcement Targeted) — the most significant opportunity available to first-time DWI defendants in Harris County. Complete DIVERT and your charge is dismissed. Not deferred adjudication — dismissed. That distinction matters for your record, your professional license, and your immigration status in ways that are hard to overstate.
DIVERT Eligibility: You Must Meet All of These
- First-time DWI with no prior criminal history
- BAC below .15 at time of test (or no test taken)
- No accident involving injury or death
- No commercial vehicle involved
- No passenger under 15 in the vehicle
What DIVERT Requires (12-Month Program)
- Drug and alcohol assessment by a licensed counselor
- Any treatment recommended by the assessment (outpatient counseling, AA/NA meetings)
- 12-hour DWI Education Program
- Community service hours
- Monthly reporting to a DIVERT supervision officer
- Ignition interlock device on every vehicle you drive
- Random alcohol and drug testing
- Victim impact panel attendance
What You Get When You Finish DIVERT
The DA’s Office files a motion to dismiss. Your charge is dismissed — and unlike deferred adjudication, a DIVERT dismissal qualifies for expunction. After expunction, the arrest record is destroyed and you can legally deny it occurred on most employment and licensing applications. For first-time DWI defendants, DIVERT is the single most favorable outcome available in Harris County short of a not-guilty verdict at trial.
How Herman Martinez Defends First-DWI Cases
Before evaluating DIVERT, Herman reviews every case for suppression challenges and outright dismissal grounds:
Challenging the Traffic Stop
Every DWI arrest starts with a traffic stop. The Fourth Amendment requires reasonable suspicion — specific, articulable facts — that a traffic law was violated. Vague driving patterns, anonymous tips without corroboration, or pretext stops may not meet this standard. Herman immediately subpoenas dashcam footage, bodycam recordings, and radio communications to analyze the stop’s legal basis.
Attacking Field Sobriety Test Administration
The three NHTSA-standardized field sobriety tests (HGN, walk-and-turn, one-leg-stand) are administered and scored by the arresting officer — not a physician or neurologist. These tests are affected by medical conditions, medications, footwear, road surface, lighting, fatigue, and anxiety that have nothing to do with alcohol. Herman cross-examines officers on their training records and the specific conditions present on the night of the arrest.
Challenging the Breath or Blood Test
Texas DWI cases increasingly involve blood draws rather than breath tests. Herman subpoenas the Intoxilyzer 9000’s calibration logs, the machine’s maintenance records, and the technical supervisor’s certification file for breath cases. Blood cases require valid collection by a licensed person, proper anticoagulant/preservative ratios, refrigerated storage, documented chain of custody, and accurate gas chromatography analysis — each a potential suppression point.
Procedural Violations
Texas requires officers to observe you for 15 uninterrupted minutes before a breath test to rule out mouth alcohol from belching or vomiting. Incorrect DIC-24 warning delivery, improper HGN administration, or failure to properly document the observation period all create suppression arguments.

| Arraignment | 2–6 weeks after arrest |
| ALR hearing | 4–8 weeks after request |
| Discovery (video, blood results) | 30–120 days post-arraignment |

Clearing Your Record After a First DWI in Texas
Texas expunction law is strict: a DWI conviction cannot be expunged. But:
- Dismissal (including DIVERT) → eligible for expunction after a waiting period
- Acquittal at trial → immediately eligible for expunction
- Deferred adjudication → NOT eligible for expunction, but may qualify for an Order of Non-Disclosure after 2 years
This is why the outcome — not just “avoiding conviction” — drives Herman’s strategy. Dismissal and acquittal create a clear path to a clean record. Deferred adjudication doesn’t.
Common Questions About a First DWI in Harris County
Will I go to jail for a first DWI?
Most first-time defendants do not serve additional jail time beyond booking. Probation and community service are the norm in Harris County for eligible first offenders. But a conviction can carry up to 180 days if the case goes to trial or you plead guilty without a favorable plea structure.
Will my driver’s license be suspended automatically?
Not if you request the ALR hearing within 15 days. If you miss the deadline, your license is suspended automatically 40 days after arrest. Even with a suspension, an occupational driver’s license lets you drive to work, school, and medical appointments during the suspension period.
How much does a first DWI actually cost?
Beyond attorney fees: up to $2,000 in fines, $300–$500 court costs, $70–$150 DWI education course, $100–$200/month for ignition interlock, $125 DPS reinstatement fee, and $1,000–$1,500/year in DPS surcharges for 3 years. Total out-of-pocket costs for a conviction routinely exceed $10,000.
Can I get the charge reduced to reckless driving?
A “wet reckless” reduction is possible but is not commonly offered by the Harris County DA’s Office for standard first-offense DWIs. The DIVERT program — which results in a full dismissal — is the DA’s preferred resolution for eligible first-time defendants, and a dismissal is a better outcome than a reckless driving plea on every metric.
If you were arrested for DWI in Houston or Harris County, call Herman Martinez immediately at (713) 242-1779. The 15-day ALR deadline doesn’t pause for holidays, weekends, or the time it takes to figure out what to do next.
