      A DWI arrest in Melissa triggers two simultaneous legal proceedings: a criminal case and an administrative license suspension case through DPS. Melissa’s location along Highway 75 in northern Collin County makes it a frequent DWI enforcement corridor, with both Melissa Police Department and Collin County Sheriff’s deputies conducting traffic stops along the highway and surrounding roads.

      At Deandra Grant Law, DWI defense is where our firm was built. Our attorneys hold ACS-CHAL Forensic Lawyer-Scientist designations which is advanced forensic science training that allows us to challenge the prosecution’s evidence at the scientific level.

      In addition, Deandra Grant literally “wrote the book” on DWI defense in Texas: The Texas DWI Manual

      Why the Science Behind Your DWI Matters

      • Blood testing: GC-FID methodology, coelution, contamination, in vitro fermentation, improper blood draws
      • Breath testing: Partition ratio variability, mouth alcohol, medical conditions, Intoxilyzer 9000 limitations
      • Field sobriety tests: NHTSA protocol challenges
      • Retrograde extrapolation: Challenging the prosecution’s BAC math

      DWI Penalties in Texas

      • First offense (Class B): 72 hours–180 days jail, up to $2,000 fine, license suspension
      • BAC 0.15+ (Class A): Up to 1 year jail, $4,000 fine, mandatory interlock, permanent conviction
