Read NowLewisville DWI Lawyers
A DWI arrest in Lewisville triggers two simultaneous legal proceedings: a criminal case and an administrative license suspension through DPS. Lewisville’s position along the I-35E corridor makes it one of the highest-volume DWI enforcement areas in Denton County, with the Lewisville Police Department conducting regular traffic patrols, saturation enforcement, and holiday DWI campaigns.
At Deandra Grant Law, DWI defense is where our firm was built. Our attorneys hold ACS-CHAL Forensic Lawyer-Scientist designations, and our Denton office serves Lewisville residents with convenient access to the Denton County Courts Building.
Why the Science Behind Your DWI Matters
Most DWI defense attorneys challenge procedure. Our forensic training allows us to challenge the science itself:
- Blood testing: GC-FID methodology, coelution, contamination, in vitro fermentation, improper blood draw procedures
- Breath testing: Partition ratio variability, mouth alcohol contamination, GERD/diabetes false positives, Intoxilyzer 9000 limitations
- Field sobriety tests: NHTSA protocol challenges, administration and scoring errors
- Retrograde extrapolation: Challenging the prosecution’s BAC calculations
Lewisville DWI Enforcement
The I-35E corridor through Lewisville is a primary DWI enforcement zone. The Lewisville Police Department’s traffic unit conducts regular patrols along I-35E, Highway 121, and the Old Town entertainment district. Lewisville PD also participates in multi-agency DWI task forces during holidays and special events, including enforcement around Lewisville Lake during summer months.

The 2019 DWI Law Changes
If your BAC was below 0.15 (or no test was obtained), you may be eligible for deferred adjudication which results in the possibility of a dismissal and the ability to seal your record. If your BAC was 0.15 or higher, conviction for this Class A misdemeanor will lead to a permanent conviction. Our training is the tool that can challenge BAC accuracy near the 0.15 threshold.
