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.
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.

The BWI rulesHow 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 ruleFirst 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.
Why Dallas Clients Choose This Firm
What decides a DWI case is how well your lawyer understands the evidence.
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.

As Seen In
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.
