San Antonio DWI Lawyer: What to Expect When Facing a DWI Charge in Texas
A DWI charge in San Antonio — or anywhere in Texas — sets off a legal process that moves on two separate tracks at once. One is the criminal case. The other is an administrative action against your driver's license. Understanding how each track works, what variables shape outcomes, and where an attorney typically fits in helps people facing these charges make sense of what's ahead.
What "DWI" Means Under Texas Law
Texas uses the term DWI (Driving While Intoxicated) rather than DUI, though both terms appear in everyday conversation. Under Texas Penal Code, a person is legally intoxicated if their blood alcohol concentration (BAC) is 0.08% or higher, or if they've lost the normal use of their mental or physical faculties due to alcohol, drugs, or a combination of both.
A standard first-offense DWI in Texas is a Class B misdemeanor. That can escalate quickly depending on circumstances:
| Situation | Classification |
|---|---|
| First offense (BAC under 0.15) | Class B Misdemeanor |
| First offense (BAC 0.15 or higher) | Class A Misdemeanor |
| Second offense | Class A Misdemeanor |
| Third offense | Third-Degree Felony |
| DWI with child passenger | State Jail Felony |
| Intoxication assault | Third-Degree Felony |
| Intoxication manslaughter | Second-Degree Felony |
These distinctions matter because they affect potential jail time, fines, probation eligibility, and long-term record consequences.
The Two-Track Process: Criminal Court and ALR
Most people arrested for DWI in Texas face proceedings on two fronts simultaneously.
Criminal court handles the charge itself — misdemeanor or felony — through the Bexar County court system for San Antonio arrests. This process involves arraignment, pretrial hearings, potential plea negotiations, and possibly a trial.
The Administrative License Revocation (ALR) process is separate and runs through the Texas Department of Public Safety (TxDPS). If a driver fails or refuses a breath or blood test, their license is subject to automatic suspension. To challenge that suspension, a hearing must be requested — typically within 15 days of the arrest date. Missing that window generally means the suspension proceeds without a hearing.
These two processes are independent. Winning in criminal court doesn't automatically resolve the ALR action, and vice versa.
What a San Antonio DWI Defense Attorney Generally Does
A defense attorney in a DWI case typically gets involved in both tracks. On the criminal side, they review the arrest record, police report, dashcam and bodycam footage, field sobriety test administration, and the chain of custody for any blood or breath samples. On the administrative side, they may request and represent at the ALR hearing.
Common defense approaches attorneys evaluate include:
- Lawfulness of the traffic stop — whether the officer had reasonable suspicion to pull the driver over
- Field sobriety test administration — standardized tests (HGN, walk-and-turn, one-leg stand) have specific protocols; deviations can be challenged
- Breathalyzer calibration and maintenance records
- Blood draw procedures — improper handling can affect admissibility
- Rising BAC arguments — whether BAC at time of driving differed from BAC at time of testing
Attorneys in Texas DWI cases typically work on either a flat fee or an hourly rate, rather than the contingency fee structure common in civil personal injury cases. Flat fees are common for straightforward misdemeanor cases; more complex or felony matters often involve hourly billing or tiered flat-fee arrangements.
Potential Consequences Beyond the Courtroom 🚨
A DWI conviction in Texas carries consequences that extend well past any jail sentence or fine:
- License suspension (length varies by offense and circumstances)
- Annual surcharges under Texas's Driver Responsibility Program (note: the DRP was repealed, but surcharge history may still apply to older cases)
- Ignition interlock device requirements — mandatory for certain offenses, including BAC of 0.15 or higher
- SR-22 insurance requirement — Texas requires this filing to reinstate a suspended license, which typically raises insurance premiums significantly
- Employment consequences — particularly for CDL holders or jobs requiring background checks
- Immigration consequences — for non-citizens, a DWI conviction can have serious collateral effects
How Case Outcomes Vary
No two DWI cases resolve the same way. Outcomes depend on a wide set of variables:
- Prior criminal history — a first offense is treated very differently than a second or third
- BAC level and test type — blood tests are generally viewed as more reliable than breath tests and harder to challenge
- Whether an accident occurred — crashes involving injuries or property damage add layers of exposure
- Quality and completeness of the stop documentation
- Prosecutor policies in Bexar County — local charging and plea practices differ from county to county across Texas
- Whether a jury trial is requested — San Antonio juries and bench trial outcomes can differ meaningfully
Deferred adjudication is not available for DWI in Texas, which limits one common alternative that exists for many other offenses. However, first-time offenders may be eligible for probation rather than jail time, depending on facts and negotiation.
What the Missing Pieces Look Like
The specifics of any DWI case in San Antonio — the officer's body camera footage, the exact BAC reading, whether a blood draw was voluntary or warranted, prior record, and the precise charge filed — are what determine the realistic range of outcomes. Texas law sets the framework. The facts fill it in.
General information about how DWI defense works can orient someone new to the process, but the 15-day ALR deadline, the charge classification, and the evidentiary issues in a specific arrest are details that only apply to one person's situation at a time.
