Houston DWI Attorney: What to Expect When Facing a Drunk Driving Charge in Texas
A DWI arrest in Houston sets off a chain of legal and administrative events that move on parallel tracks — one through the criminal court system, one through the Texas Department of Public Safety. Understanding how those tracks work, what decisions come up along the way, and what a defense attorney typically does in this process can help anyone 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 for most adult drunk driving offenses. Under the Texas Penal Code, a person is legally intoxicated if they have a blood alcohol concentration (BAC) of 0.08% or higher, or if alcohol or drugs have impaired their normal use of mental or physical faculties — regardless of BAC.
Texas does have a separate DUI classification, but it applies specifically to minors under 21 with any detectable amount of alcohol in their system. For adults, DWI is the operative charge.
The Two Tracks: Criminal Case and License Suspension
Criminal Proceedings
A first-offense DWI in Texas is typically charged as a Class B misdemeanor, which carries potential consequences including fines, license suspension, and jail time. The case moves through the Harris County court system, which handles Houston-area criminal matters.
Charges can escalate significantly based on:
- Prior DWI convictions
- BAC of 0.15% or higher (elevated to Class A misdemeanor)
- A child passenger in the vehicle
- An accident resulting in serious injury or death (felony charges)
Administrative License Revocation (ALR)
Separate from the criminal case, the Texas Department of Public Safety initiates an automatic license suspension process after a DWI arrest. This is the ALR process, and it operates independently of whether a person is convicted in court.
⚠️ In Texas, a driver typically has 15 days from the date of arrest to request an ALR hearing to contest the suspension. Missing that window generally results in automatic suspension. This deadline is administrative, not criminal — and it often catches people off guard.
What a Houston DWI Attorney Generally Does
Defense attorneys in DWI cases typically take on several distinct functions:
Challenging the traffic stop — Police must have reasonable suspicion to pull a driver over. If the stop itself was improper, evidence gathered afterward may be challengeable.
Examining field sobriety tests — Standardized field sobriety tests (walk-and-turn, one-leg stand, horizontal gaze nystagmus) are subject to scrutiny regarding administration and conditions.
Contesting chemical test results — Breathalyzer calibration records, blood draw procedures, chain of custody for samples, and laboratory handling can all be examined for procedural issues.
Requesting the ALR hearing — Attorneys typically handle the administrative license hearing alongside the criminal defense, often using ALR hearings to gather information about the arresting officer's testimony before trial.
Negotiating with prosecutors — Depending on the facts, attorneys may negotiate for reduced charges, deferred adjudication, or participation in programs like ignition interlock or DWI education courses.
Key Variables That Shape DWI Outcomes in Texas
No two DWI cases are identical. The factors that most significantly influence how a case develops include:
| Variable | Why It Matters |
|---|---|
| BAC level at time of arrest | Affects charge severity and prosecution approach |
| Prior DWI history | Determines felony vs. misdemeanor classification |
| Whether an accident occurred | Can trigger enhanced charges or civil liability |
| Type of chemical test used | Breath vs. blood tests have different challenge strategies |
| Dashcam or bodycam footage | May support or undercut either side's position |
| Whether a child was present | Mandatory felony enhancement in Texas |
| Harris County court assigned | Judges and prosecutors vary by court |
What Happens in Court
Most DWI cases do not go to trial. A significant portion are resolved through plea negotiations, where the defense and prosecution reach an agreement on charges and sentencing. When cases do proceed to trial, the defendant can choose a judge trial or jury trial.
🔍 Deferred adjudication is not available for standard DWI charges in Texas — a notable distinction from many other offenses. However, certain programs like pretrial diversion may be available in some Harris County courts depending on circumstances, including whether it's a first offense.
Penalties Beyond Fines and Jail
Even a first-offense conviction carries consequences that extend well past sentencing:
- Annual surcharges to the Texas Driver Responsibility Program (note: this program was repealed for offenses after September 2019, but older cases may still have outstanding surcharges)
- Ignition interlock device requirements
- SR-22 insurance filing, which signals to insurers that a driver is high-risk and typically raises premiums substantially
- Employment and licensing consequences depending on profession
- A permanent criminal record if not handled through available diversionary options
How Attorney Fees Typically Work
Unlike personal injury cases, DWI defense attorneys are not paid on contingency. They charge flat fees or hourly rates, depending on case complexity. A straightforward first-offense misdemeanor will generally cost less than a felony DWI with an accident and injuries involved. Fee structures vary widely across Houston-area firms, and complexity — including whether a case goes to trial — significantly affects total cost.
The Gap Between General Knowledge and Your Case
Texas DWI law has specific procedural rules, deadlines, and court-by-court variations that don't apply uniformly across other states — or even uniformly across Houston's court system. The strength of the evidence, the arresting officer's record, the type of chemical test used, and what happened at the scene all shape what options exist and how the case is likely to develop. Those details are what determine the difference between outcomes — not the general framework alone.
