    DWI Defense in Dallas

    Facing a DWI in Dallas County?

    Deandra Grant Law defends people charged with DWI in Dallas and throughout Dallas County. We handle every level of the offense, from a first-offense DWI to high-BAC, repeat, and felony charges, including DWI with a child passenger, intoxication assault, intoxication manslaughter, and drugged driving. Dallas clients work from our Oak Lawn office at 3300 Oak Lawn Avenue, eight minutes from the Frank Crowley Courts Building. Call (214) 225-7117 any hour.

    A DWI charge is not a conviction, and the evidence behind it is rarely as solid as it looks. This firm has tried more than 500 cases to verdict and built its reputation on the science, led by a forensic lawyer-scientist who wrote The Texas DWI Manual and trains other DWI attorneys. That matters more in Dallas than almost anywhere. The county tests blood at its own SWIFS lab rather than the state DPS lab, which means its methods, calibration records, and analysts can be examined and challenged on their own terms.

    Getting started costs nothing. Call or schedule online to talk through what happened and understand your options. The sooner we start, the more we can protect, and in Texas you have just 15 days from the notice of suspension to request the hearing that keeps your license.

    15-Day Deadline

    Your license is on a 15-day clock

    It starts when you receive the notice of suspension, not automatically at arrest. In a blood case that notice often arrives by mail weeks later, so the deadline may still be ahead of you.

    What We Defend

    Dallas DWI Charges We Handle

    Every Dallas County DWI charge, from a first offense to intoxication manslaughter.

    First-Offense DWI

    Driving while intoxicated with no prior convictions, a Class B misdemeanor.

    First DWI penalties

    Second DWI

    A DWI with one prior conviction, a Class A misdemeanor with mandatory jail time.

    Second DWI penalties

    Third DWI

    A DWI with two prior convictions, a third-degree felony carrying two to ten years.

    Third DWI penalties

    DWI, BAC 0.15+

    A result of 0.15 or higher raises a first DWI to Class A.

    Why 0.15 matters

    DWI with Child Passenger

    A passenger under fifteen turns a misdemeanor DWI into a felony.

    Why this is a felony

    Intoxication Assault

    Causing serious bodily injury to another while intoxicated, a third-degree felony.

    Assault penalties

    Intoxication Manslaughter

    Causing a death while intoxicated, a second-degree felony carrying prison time.

    Manslaughter penalties

    Underage DWI

    Drivers under twenty-one face DUI charges for any detectable amount of alcohol.

    DWI vs. DUI

    Drug DWI

    A DWI where the intoxicant is a drug, prescribed or illegal, with no breath number involved.

    How they prove it

    Marijuana DWI

    Marijuana and edibles can support a DWI without any measurable level.

    The marijuana rules

    Prescription Drug DWI

    A valid prescription is no defense if the medication impaired your driving.

    Prescription rules

    CDL DWI

    A commercial license is disqualified even for a DWI in your own car.

    CDL consequences

    Boating DWI (BWI)

    Operating a boat while intoxicated, prosecuted much like a driving DWI.

    The BWI rules
    Local Knowledge

    How a DWI Case Moves Through Dallas County

    Dallas runs its DWI cases differently from the counties around it. Here is the path from the arrest to the end of the case. Find where you are on it.

    Arrest

    Dallas County DWI arrests come from Dallas Police, the Dallas County Sheriff's Office, DPS troopers on the highways, and the suburban departments in Garland, Irving, Mesquite, and the rest of the county.

    Booking

    After a Dallas arrest you are booked at the Lew Sterrett Justice Center, next door to the courthouse.

    Bond and release

    A magistrate sets your bond and any release conditions before your first court setting. Time already spent in Lew Sterrett counts against any sentence later.

    Blood analysis

    Dallas tests blood at the county's own Southwestern Institute of Forensic Sciences rather than the state DPS lab. Its methods, calibration records, and analysts are all discoverable.

    ALR hearing

    Your license case runs separately from the criminal case. Request the hearing within 15 days of the notice of suspension, and the hearing becomes the first chance to question the officer under oath.

    The 15-day rule

    First setting

    Dallas DWI cases run through the Frank Crowley Courts Building. Misdemeanors are set in the County Criminal Courts. Felonies go to the Criminal District Courts in the same building.

    Who prosecutes

    The Dallas County District Attorney charges DWIs through separate misdemeanor and felony divisions, each with its own process and timelines.

    Resolution

    Dallas does not offer a DWI pretrial diversion program. DIVERT covers drug cases only. That makes the defense itself the path to a better outcome here, whether that ends in dismissal, reduction, or trial.

    Learn More About Our Firm
    After You Hire Us

    What We Do on Every Case

    From the first call, in order:

    • Request your ALR hearing before the 15-day deadline and use it to question the officer under oath.
    • Demand the dash and body camera video before it is destroyed.
    • Pull the full discovery file: offense report, calibration and maintenance logs, lab records, certifications.
    • Read the underlying chemistry ourselves: the chromatograms and the QC data, not the summary report.
    • Re-score the field sobriety tests against NHTSA protocol, on video.
    • File the motions the evidence supports, because suppression is how DWI cases end.
    • Build your mitigation file, with clinical assessments, at no cost to you.
    • Try the case if the offer is not right. Prosecutors know which firms try cases.

    We quote a flat fee after a consultation at no cost to you, so the investment is known before you commit.

    Serving All of Dallas County

    We defend DWI cases from every corner of Dallas County: Dallas itself, from Oak Lawn and Uptown to Deep Ellum and downtown, plus Garland, Irving, Mesquite, Grand Prairie, Carrollton, Richardson, Highland Park, Rowlett, DeSoto, Duncanville, Cedar Hill, and Lancaster. If the arrest happened in Dallas County, the case lands at Frank Crowley, and that is a building we work in every week. A few of these cities cross a county line. A stop on the Rockwall County side of Rowlett is heard in Rockwall. A stop on the Denton County side of Carrollton is heard in Denton. The Collin County parts of Richardson and Sachse go to McKinney, where our Allen office appears. We work in all of those courts.

    Wherever the stop happened in Dallas County, the arrest books at Lew Sterrett and the case is set at Frank Crowley. What changes is who made the stop.

    North Dallas and Preston Hollow

    Stops on the Dallas North Tollway, LBJ Freeway, and Preston Road are worked by the Dallas Police North Central division.

    Oak Cliff and South Dallas

    I-35E, I-30, Loop 12, and US-67 through Oak Cliff produce a large share of Dallas County DWI arrests, most from the Southwest and South Central divisions.

    Lakewood, East Dallas, and White Rock

    Garland Road, Gaston Avenue, and the streets around White Rock Lake are Northeast division territory.

    DWI is the majority of our work, not all of it. The same attorneys handle these charges in the same courthouses.

    Dallas County

    Dallas DWI Questions, Answered

    Which court will my Dallas DWI case be in?

    Dallas County DWI cases are heard at the Frank Crowley Courts Building at 133 N. Riverfront Blvd. A first or second DWI goes to one of the County Criminal Courts. A felony DWI, intoxication assault, or intoxication manslaughter goes to a Criminal District Court in the same building. Our Dallas County court guide covers the whole building.

    Does Dallas County offer DWI diversion?

    No. Dallas County's DIVERT program covers drug cases only. There is no pretrial diversion for DWI, so the outcome depends on the strength of the defense. Start with our guide to the most common DWI defenses in Texas.

    They took my blood in Dallas. Is my case over?

    No. Dallas blood goes to SWIFS, the county's own lab. Every step of that analysis is discoverable, from the draw to the chromatogram to the analyst's training file. We request all of it and review it ourselves. Our guide to the evidence in a Texas DWI case explains what we look for.

    How long do I have to save my license after a Dallas DWI?

    Fifteen days from the date you receive the notice of suspension. If you refused a test or blew over 0.08, the officer handed you the notice at arrest. If blood was drawn, the notice comes by mail after the results are in. Our guide to the 15-day deadline walks through the request.

    What does a DWI lawyer in Dallas cost?

    We quote a flat fee after a consultation at no cost. The fee depends on the charge level, whether blood was drawn, and whether the case is headed to trial. You know the number before you commit, and there are no hourly surprises. Payment plans are available. Our fee guide explains what a DWI defense should and should not cost.

    Can a first DWI in Dallas County end without a conviction?

    Yes. A first DWI can end in dismissal, an acquittal at trial, or a reduction to a non-DWI offense. Which path is available depends on the stop, the testing, and the evidence in the file. Our guide to deferred adjudication covers the other route a first DWI can take.

    Will I go to jail for a first DWI in Dallas County?

    A first-offense Class B DWI carries a range of 72 hours to 180 days in jail. Many first offenses in Dallas County resolve with probation rather than jail time, but the outcome depends on the facts and the record.

    I was just arrested for DWI in Dallas. What should I do first?

    Write down everything you remember while it is fresh. Keep every piece of paper from the arrest, especially the notice of suspension. Do not discuss the case with anyone but a lawyer. Then call us so we can request your ALR hearing before the 15-day window closes. Our step-by-step guide covers the rest: What to Do After a DWI Arrest.

    Can you handle my case if I was arrested outside Dallas County?

    Yes. We have offices in Dallas, Fort Worth, Allen, Denton, Rockwall, and Waco, and we appear in the courts across North and Central Texas. Tell us where the stop happened and we will route you to the right office. Find your county on our locations page.

    Do I have to come to the office, or can we meet remotely?

    Either. Consultations are at no cost in person, by phone, or by video. Most Dallas clients start with a phone call and meet in person before the first court date.

    Do I need a Dallas DWI attorney, or will any criminal lawyer do?

    Any licensed lawyer can take the case. The question is whether they can read a SWIFS chromatogram, cross-examine on field sobriety protocol, and know how each Frank Crowley court runs. DWI is a science case wearing a criminal charge. Our guide to choosing a DWI lawyer covers what actually matters.

    Where were you arrested? We also serve the suburbs.

    Garland, Irving, Mesquite, Grand Prairie, and every other Dallas County city all prosecute at Frank Crowley. Wherever the stop happened, we defend it. See our Dallas County guide for how a case moves through the building.

    How much does a consultation cost?

    Nothing. Every consultation is free and confidential, with no obligation to hire us.

    Is a DWI a felony in Texas?

    Usually not the first time. A first DWI is a Class B misdemeanor, or Class A if your alcohol concentration was 0.15 or higher, and a second DWI is a Class A misdemeanor. It becomes a felony with a third offense (third-degree felony, two to ten years), any DWI with a passenger under 15 (state jail felony), intoxication assault (third-degree felony), or intoxication manslaughter (second-degree felony). Our felony DWI guide covers each level.

    What is the legal alcohol limit in Texas?

    0.08 for most drivers, 0.04 for anyone holding a commercial driver license, and any detectable amount for a driver under 21. The number is not the whole story: Texas also defines intoxication as losing the normal use of your mental or physical faculties, so a driver under 0.08 can still be charged, and a 0.08 result can still be challenged on how the sample was taken and tested. See what 0.08 actually means.

    How long can my license be suspended after a Dallas DWI?

    The administrative suspension comes first. A failed breath or blood test brings 90 days for a first offense, and a refusal brings 180 days. A prior alcohol-related contact in the last ten years raises those to one year and two years. A conviction can add its own suspension of 90 days to a year. Requesting the ALR hearing within 15 days of the notice of suspension is the only way to contest the first one, and an occupational license can keep you driving in the meantime. See our license guide.
