Tarrant County DWI Attorney

DWI charge classifications in Tarrant 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 Tarrant County are prosecuted by the Tarrant County Criminal District Attorney’s Office and tried at the Tim Curry Criminal Justice Center, 401 W. Belknap Street, Fort Worth. Misdemeanor DWI — first-offense Class B and Class A — is filed in the county’s ten County Criminal Courts (Nos. 1–10), while felony DWI (third offense, child passenger, intoxication assault, or intoxication manslaughter) is filed in the felony district courts. Both divisions sit in the same downtown-Fort Worth courthouse.

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 Tarrant County DWI client retains us.

Defense attack points on a Tarrant 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 Tarrant 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.

Tarrant County DWI: enforcement and prosecution

Tarrant County generates significant DWI volume because of the freeway network threading through it: I-35W down the county's spine, I-30 east–west through downtown Fort Worth and Arlington, I-20 across the southern tier, the I-820 (Loop 820) beltway around Fort Worth, and heavily traveled state routes such as SH 121, SH 183 (Airport Freeway), SH 360, SH 114, and the Chisholm Trail Parkway toll road. Enforcement comes from three main sources: the municipal police departments that patrol their own city limits — Fort Worth, Arlington, Grand Prairie, Mansfield, North Richland Hills, Euless, and their neighbors — the Tarrant County Sheriff's Office in unincorporated areas, and Texas DPS troopers working the interstates. Most Tarrant County DWI arrests begin as ordinary traffic stops — a lane drift, an expired registration, a headlight out, or speeding — that escalate once the officer reports an odor of alcohol, slurred speech, or bloodshot eyes.

After a DWI arrest in the county, the driver is booked into the Sheriff's downtown jail — intake at the Tarrant County Corrections Center, 100 N. Lamar Street, with custody at the Lon Evans Corrections Center, 600 W. Weatherford Street in Fort Worth — and brought before a magistrate within 48 hours, who sets bond and can enter conditions such as an ignition-interlock requirement or alcohol monitoring. From there the criminal case is filed in a County Criminal Court (misdemeanor) or a felony district court, while the parallel ALR license case proceeds separately at SOAH on its own 15-day clock. Handling both tracks from day one is the practical core of a Tarrant County DWI defense.

SFST, breath, and blood evidence in Tarrant County prosecutions

Once impairment is suspected, the officer conducts the Standardized Field Sobriety Tests (SFSTs) — Horizontal Gaze Nystagmus (HGN), Walk-and-Turn, and One-Leg Stand. These tests are scored against National Highway Traffic Safety Administration (NHTSA) protocols; deviations from those protocols are routine bases for defense challenges. Breath testing is performed on the Intoxilyzer 9000 (now replacing the 5000 across most Texas jurisdictions). If a breath sample is refused or unavailable, the officer typically obtains a search warrant for blood, which is drawn at a hospital or jail-trained phlebotomist station. The Texas Department of Public Safety Crime Laboratory analyzes blood samples by gas chromatography. Each step — stop, SFST administration, breath operator certification, warrant probable cause, blood draw chain of custody, laboratory analysis — presents discrete defense opportunities.

Because so many Tarrant County stops occur on high-volume freeways such as I-35W, I-30, and Loop 820, blood-draw warrants are common when a breath sample is refused, and the resulting samples are analyzed by the Texas DPS crime laboratory. Every handoff in that chain — the warrant affidavit, the draw itself, the transport, and the lab analysis — is a documented step the defense can test, which is why subpoenaing the complete record early is central to a Tarrant County DWI case rather than an afterthought.

Penalties, ALR, and occupational license

The full Texas penalty ladder — the fine and jail ranges at each offense level, the ALR suspension periods, and the Occupational Driver's License available under Texas Transportation Code § 521.241 — is laid out on our statewide DWI defense page, and the license-consequence section above covers the essentials. What is specific to Tarrant County is where those consequences play out. A misdemeanor DWI plea or trial happens in one of the ten County Criminal Courts (Nos. 1–10); a felony DWI, in the district courts; and for eligible felony repeat-DWI defendants, Tarrant County runs the Felony Alcohol Intervention Program (FAIP), a structured treatment-and-monitoring diversion track supervised through the county's community-supervision department. Screening a case for FAIP or for a negotiated reduction, and coordinating the criminal case with the SOAH ALR hearing, is the core of a local DWI defense. L and L Law Group handles the ALR hearing, the criminal case, and the occupational-license petition together on every retained Tarrant County DWI.
