San Antonio DWI Attorney: What Drivers Need to Know About DWI Charges and Legal Representation
A DWI charge in San Antonio — or anywhere in Texas — sets off a legal and administrative process that affects your driving privileges, your record, and potentially your insurance and employment. Understanding how that process works helps you make more informed decisions, even before you speak with anyone in a courtroom.
What DWI Means in Texas
DWI stands for Driving While Intoxicated. In Texas, a person is legally intoxicated when their blood alcohol concentration (BAC) reaches 0.08% or higher — or when they've lost the normal use of their mental or physical faculties due to alcohol, drugs, or a combination of both.
Texas does not use the term DUI for adults. DUI in Texas is reserved for minors with any detectable amount of alcohol. Adult charges are filed as DWI, regardless of the substance involved.
What Happens After a DWI Arrest in San Antonio
Two separate processes begin almost immediately after an arrest:
1. The Criminal Case
This moves through the Bexar County court system. Charges can range from a Class B misdemeanor (first offense, BAC under 0.15) to a Class A misdemeanor (BAC of 0.15 or higher, or repeat offense) to a felony (third offense, or if a child passenger was present, or if someone was seriously injured or killed).
2. The Administrative License Revocation (ALR) Process
This is handled separately by the Texas Department of Public Safety (DPS), not the criminal courts. When you're arrested for DWI and either fail or refuse a chemical test, your license is subject to automatic suspension. You have 15 days from the date of arrest to request an ALR hearing — if you miss that window, the suspension takes effect automatically.
These two tracks run on different timelines and involve different procedures. A San Antonio DWI attorney typically handles both.
Why DWI Cases Involve More Complexity Than Many Drivers Expect
A DWI arrest is not the same as a conviction. Several factors shape how a case proceeds:
- How the traffic stop was initiated — whether reasonable suspicion existed
- How field sobriety tests were administered — standardized tests have specific procedural requirements
- How the breath or blood test was conducted — equipment calibration, chain of custody, and testing conditions can all be challenged
- Prior driving history — prior DWI convictions in Texas or other states affect charge severity and sentencing ranges
- Whether an accident or injury was involved — this can elevate a misdemeanor to a felony
- BAC level at the time of testing — results significantly above 0.08% carry different legal weight than borderline readings
- Presence of a minor in the vehicle — Texas law treats this as a separate, more serious offense
What a DWI Attorney Actually Does ⚖️
A DWI attorney in San Antonio handles tasks across both the criminal and administrative tracks:
On the ALR side, they can request and represent you at the hearing that determines whether your license gets suspended while the criminal case is pending. Winning that hearing doesn't resolve the criminal charge — but it can preserve your driving privileges during the process.
On the criminal side, they review arrest records, dashcam and bodycam footage, chemical test documentation, and officer conduct. They identify whether any evidence was gathered improperly, whether the stop itself was legally valid, and whether any procedural errors open the door to suppression or dismissal.
They also negotiate with the Bexar County District Attorney's office, which may result in reduced charges, deferred adjudication, or plea agreements — depending on the specifics of the case and the defendant's record.
How DWI Penalties Scale in Texas
| Offense Level | Potential Jail Time | Fine | License Suspension |
|---|---|---|---|
| 1st offense (Class B misdemeanor) | 72 hours – 180 days | Up to $2,000 | 90 days – 1 year |
| 1st offense, BAC ≥ 0.15 (Class A) | Up to 1 year | Up to $4,000 | 90 days – 1 year |
| 2nd offense (Class A misdemeanor) | 30 days – 1 year | Up to $4,000 | 180 days – 2 years |
| 3rd offense (3rd-degree felony) | 2 – 10 years | Up to $10,000 | 180 days – 2 years |
| DWI with child passenger (felony) | 180 days – 2 years | Up to $10,000 | 180 days – 2 years |
These figures reflect Texas statutory ranges. Actual outcomes vary based on case specifics, prior record, and court decisions.
The Insurance and Vehicle Consequences 🚗
Beyond criminal penalties, a DWI conviction in Texas typically triggers:
- SR-22 filing requirements — Texas may require proof of high-risk insurance coverage, often for two years or more
- Ignition interlock device (IID) installation — required in many DWI cases, including as a condition of bond, probation, or an occupational license
- Occupational license eligibility — if your license is suspended, Texas allows an application for a restricted license to drive to work, school, or essential appointments
Each of these carries its own cost and process. SR-22 premiums vary significantly by insurer, driving history, and coverage type. IID installation and monthly monitoring fees are typically the driver's responsibility.
What Shapes the Outcome Most
No two DWI cases in San Antonio move through the system the same way. The quality of the evidence, the specific court and judge, the defendant's prior record, and the details of how the arrest was conducted all factor into what options exist and what results are realistic.
The 15-day ALR deadline is the most time-sensitive piece. After that window closes, the administrative suspension process moves forward without an opportunity to contest it — regardless of what happens in criminal court.
