Dallas County DWI Attorney

DWI charge classifications in Dallas County

Texas DWI offenses are classified by enhancement factors. The base charge under Tex. Penal Code § 49.04 is a Class B misdemeanor (up to 180 days county jail and $2,000 fine) when BAC is below 0.15. The Class A enhancement (up to 1 year and $4,000) applies when BAC is 0.15 or higher. Felony DWI applies on the third offense or when a child passenger is involved. Intoxication assault under § 49.07 (third-degree felony) and intoxication manslaughter under § 49.08 (second-degree felony) involve serious bodily injury or death.

Cases originating in Dallas County are prosecuted by the Dallas County District Attorney’s Office and tried at the Frank Crowley Courts Building, 133 N. Riverfront Boulevard in Dallas. A misdemeanor DWI is docketed in the County Criminal Courts (No. 1–11); a felony DWI goes to the district courts. After arrest, a driver is booked at the Lew Sterrett Justice Center, 111 W. Commerce Street, where a magistrate sets the initial bond. That bond follows the county schedule for the offense level and can be revisited by motion in the assigned court once counsel is retained.

The 15-day ALR window

Every DWI arrest in Texas triggers a parallel administrative proceeding at the State Office of Administrative Hearings (SOAH) called the Administrative License Revocation (ALR) hearing. Under Tex. Transp. Code § 524.031, the defendant has 15 days from the date of receiving notice of suspension (almost always the date of arrest) to request the ALR hearing. Miss it and the suspension takes effect automatically on the 40th day after arrest. No extensions are available.

The ALR hearing is separate from the criminal DWI case. The burden of proof at the ALR hearing is preponderance of the evidence (lower than criminal "beyond a reasonable doubt"). The Department of Public Safety is the prosecuting party at the ALR. The issues are narrow: was the stop legal, was probable cause established, was the implied-consent warning properly delivered under Tex. Transp. Code § 724.015.

An ALR win does not dismiss the criminal case but it preserves the driver’s license, locks in the arresting officer’s sworn testimony for later impeachment in the criminal proceeding, and changes the negotiation posture with the prosecutor. We file the ALR request the same day a Dallas County DWI client retains us. For a Dallas County arrest the request goes to the Department of Public Safety, and the contested hearing is set on a SOAH docket serving the Dallas region — entirely separate from the criminal setting at Frank Crowley.

Defense attack points on a Dallas County DWI

Every Texas DWI defense has the same set of attack points, applied to the specific facts of the case. The ones we work hardest in Dallas County DWI matters:

• The traffic stop. Reasonable suspicion supported by articulable facts under Terry v. Ohio and the Texas analog Carmouche v. State. We pull the dashcam and bodycam from the initial contact.
• The field-sobriety tests. NHTSA-validated standardized administration of HGN, walk-and-turn, and one-leg stand. We score the video frame-by-frame against the NHTSA training manual and identify protocol deviations.
• The 15-minute observation period. The breath-test operator must observe the suspect for 15 minutes with no oral intake before the test. We pull the body-cam to verify whether the observation was actually completed.
• The breath-test instrument. Intoxilyzer 9000 calibration log, slope-detector flags, mouth-alcohol detection, reference-sample log. We subpoena the 30-day maintenance log for the specific device.
• The blood-draw warrant. If a blood draw was taken under a warrant, we analyze the affidavit for four-corners probable cause and any Franks-hearing material misrepresentations.
• The chain of custody. From the breath or blood sample collection through the lab analysis, the chain must be unbroken. We subpoena the lab’s standard operating procedure and the analyst’s training record.

License consequences and occupational license

A first-offense DWI conviction in Texas triggers a 90-day to 1-year driver’s license suspension under Tex. Transp. Code § 521.342. ALR refusal triggers a 180-day suspension; ALR failure (BAC 0.08 or above) triggers a 90-day suspension. Second-offense and felony DWI trigger longer periods. After the suspension takes effect, the defendant may petition for an Occupational Driver’s License under § 521.241 permitting up to 12 hours per day of restricted driving for employment, household duties, school, and medical needs.

Our DWI flat fee covers the criminal case, the ALR hearing, and the occupational-license petition if needed. The structure mirrors how the case actually unfolds — three parallel proceedings on the same arrest. See our DWI defense page for the full statutory framework.

The occupational-license petition itself is filed in a Dallas County court — usually the County Criminal Court or district court handling the underlying DWI, or a court in the county where the driver lives — and the signed order must be carried alongside an SR-22 insurance certificate, with an ignition-interlock condition attached on many DWI-based suspensions. Because the criminal case at Frank Crowley, the ALR at the State Office of Administrative Hearings, and the license petition each run on their own clock, a Dallas County driver can be fighting three proceedings at once; keeping them coordinated is a core part of how we structure the defense.

Dallas County DWI: enforcement and prosecution

Dallas County generates heavy DWI volume for a straightforward reason: it carries some of the busiest roadway in Texas. Stops cluster along I-35E (Stemmons Freeway), I-30 (the Tom Landry and R.L. Thornton), the I-635 LBJ loop, I-20 and I-45, US-75 (Central Expressway), US-175 (C.F. Hawn), the Dallas North Tollway, and the President George Bush Turnpike. The Dallas Police Department makes the bulk of city arrests, backed by suburban forces — Irving, Garland, Grand Prairie, Mesquite, Carrollton, and Richardson police — by the Dallas County Sheriff’s Office in unincorporated areas, and by Texas DPS troopers working the interstates. Most Dallas County DWI cases begin as ordinary traffic stops (a lane drift, an expired registration, a burned-out headlight, speeding) that escalate once the officer reports an odor of alcohol, slurred speech, bloodshot eyes, or fumbling for a license.

SFST, breath, and blood evidence in Dallas County prosecutions

Once impairment is suspected, the officer runs the Standardized Field Sobriety Tests — Horizontal Gaze Nystagmus, Walk-and-Turn, and One-Leg Stand — scored against National Highway Traffic Safety Administration (NHTSA) protocols, and any deviation from those protocols is fair ground for a defense challenge. Breath samples in Dallas County are captured on the Intoxilyzer 9000. When a driver refuses or a breath test is unavailable, the officer typically obtains a blood-draw warrant from a Dallas County magistrate; the sample is drawn by a trained phlebotomist and analyzed by gas chromatography at the Texas DPS crime laboratory. Every link in that chain — the stop, the SFST administration, the breath operator’s certification, the four corners of the warrant affidavit, the blood draw, and the lab’s chain of custody — is a discrete point the defense can attack, and the resulting case is filed and tried at the Frank Crowley Courts Building.

Once the paperwork is filed, a Dallas County DWI is assigned to the District Attorney’s misdemeanor or felony division depending on the charge level, and the driver’s first courthouse contact is usually bond and magistration at the Lew Sterrett Justice Center on Commerce Street before the case is set at Frank Crowley. Those early settings fix the discovery deadlines under the Michael Morton Act and the timing of any breath- or blood-evidence litigation, so the sooner defense counsel enters an appearance, the more of that calendar the defense can actually influence.

Penalties, ALR, and occupational license

Texas DWI punishment scales with the offense level, and the full ladder — Class B and Class A misdemeanors, felony repeat DWI, DWI with a child passenger, intoxication assault, and intoxication manslaughter, plus the ALR suspension and the occupational-license rules — is laid out on our statewide DWI defense page. What is specific to Dallas County is where each case lands. A misdemeanor DWI is docketed in one of the eleven County Criminal Courts (No. 1 through No. 11); a felony DWI — a third offense, a DWI with a child passenger, intoxication assault, or intoxication manslaughter — is filed in one of the county’s seventeen district courts, both at the Frank Crowley Courts Building. Dallas County also runs problem-solving dockets a standard court does not: a Misdemeanor DWI Court and a Felony DWI Court built around repeat-offender supervision and treatment. For a driver facing a second or third DWI, eligibility for one of those programs can change the entire shape of a plea, which is why we raise it early.
