A first-offense DWI charge in Houston sets off two separate tracks at the same time — a criminal case in the courts and an administrative case through the Texas Department of Public Safety. Understanding what each track involves, and where an attorney typically fits in, helps clarify what's actually at stake before a single hearing takes place.
In Texas, driving while intoxicated (DWI) means operating a motor vehicle in a public place while intoxicated — defined as having a blood alcohol concentration (BAC) of 0.08% or higher, or having lost normal use of mental or physical faculties due to alcohol, drugs, or a combination of both.
A first offense generally means no prior DWI convictions on your record. However, even without prior convictions, the circumstances of the arrest can affect how the charge is classified. A BAC of 0.15% or higher, for example, can elevate a first offense from a Class B to a Class A misdemeanor under Texas law — which carries a higher range of penalties.
When a driver is arrested for DWI in Texas and either fails or refuses a breath or blood test, the arresting officer confiscates the driver's license and issues a temporary driving permit. The clock starts immediately.
The driver has 15 days from the date of arrest to request a hearing with the Texas State Office of Administrative Hearings (SOAH) to contest the license suspension. Missing that window means the suspension goes into effect automatically — typically 90 days for a test failure and 180 days for a refusal on a first offense.
This ALR process is entirely separate from the criminal charge. An attorney can request and represent a driver at the ALR hearing, and the hearing itself can sometimes produce useful information about the state's evidence before the criminal case proceeds.
A first-offense DWI in Houston typically lands in one of Harris County's county criminal courts. The criminal process generally moves through:
Potential consequences for a first-offense conviction under Texas law can include jail time (3 to 180 days for a standard Class B), fines up to $2,000 (plus court costs and surcharges), probation, a license suspension, mandatory ignition interlock, and DWI education programs. A Class A elevation changes those ranges upward.
Attorneys who handle DWI cases in Houston typically work on several fronts that a person representing themselves would have difficulty managing alone.
| Area | What an Attorney Typically Addresses |
|---|---|
| ALR hearing | Requests the hearing within the 15-day window, cross-examines officers, builds a record |
| Evidence review | Obtains dashcam/bodycam footage, blood/breath test records, officer training files |
| Motion practice | Challenges the legality of the traffic stop, arrest, or chemical test procedures |
| Plea negotiation | Evaluates whether a reduction to a lesser charge is available in specific circumstances |
| Trial representation | Presents defenses to a judge or jury if the case doesn't resolve |
The strength of any defense often depends on specific facts: whether the stop was legally justified, whether proper protocols were followed during testing, whether the testing equipment was properly maintained and calibrated, and whether any constitutional issues arise from the arrest itself.
No two cases are identical. Several variables typically affect how a Houston first-offense DWI case develops:
First offense doesn't automatically mean minimal consequences, and it doesn't automatically mean a case is easy to defend. Texas takes DWI seriously at every level. Even a clean-record first offense can result in a conviction that stays on your criminal record permanently — Texas does not allow expunction of a DWI conviction, though deferred adjudication (which would allow later expunction) is not available for DWI in Texas, unlike many other offenses.
That distinction matters significantly when considering long-term effects on employment, professional licenses, and background checks.
Most DWI attorneys in Houston work on a flat fee basis rather than hourly or contingency arrangements. Fees vary based on whether the case is expected to resolve through a plea or go to trial, and on the attorney's experience and the complexity of the facts. A case that involves a blood test, accident reconstruction, or expert witnesses typically costs more to defend than a straightforward breath test case.
Timelines vary widely. Harris County's court system moves at its own pace. A case might resolve in a few months or extend well over a year depending on docket scheduling, lab backlogs (common with blood test cases), and how actively the case is contested.
The specific facts of an arrest — what the officer observed, what tests were administered, how they were conducted, and what the records show — are ultimately what determine what defenses are available and what outcomes are realistic in any individual case.
