Why Hire Us to Defend DWI Cases

We have completed the same DWI testing and training as police officers!

Most criminal defense lawyers do not invest the time and training necessary to defend DWI cases successfully. An attorney needs a great deal of knowledge to discredit the Intoxilyzer 5000 in court and to discredit the police officer’s opinion that a person was intoxicated. If the attorney does not understand how the Intoxilyzer works, he or she cannot point out the potential testing errors. In addition, if the attorney doesn’t know the field sobriety tests and the studies that back them up, he or she cannot successfully cross-examine the police officer who administered them.

You need an attorney devoted to this area of the law. Just as you wouldn’t hire a foot doctor to perform heart surgery, you shouldn’t hire a general criminal attorney to defend a DWI case.

Deandra has Completed:

  • The Operator and Maintenance Technician course for the Intoxilyzer 5000
  • The certification course in the administration of Standardized Field Sobriety Tests
  • The Standarized Field Sobriety Testing Instructor course
  • The Drug Recognition Expert overview course
  • Over 24 hours of training in the drawing and testing of blood samples for use in DWI cases
  • The Forensic Chromatography: Theory and Practice course through the American Chemical Society and Axion Labs

Medical Conditions That Affect the Breath Test

Deandra Grant knows that multiple factors can affect a breath-test score, the ability to perform the field sobriety tests and/or the rate at which alcohol is absorbed and eliminated. These include:

  • Surgeries
  • Prescription or over-the-counter drugs
  • Diseases and medical conditions
  • Airbag deployment in an accident
  • Racial heritage
  • Type of alcohol consumed, rate of consumption, lack of food while drinking, type of diet

Factors That Affect the Performance of Standard Field Sobriety Tests

  • Weather
  • Lack of sleep or lack of coordination
  • Wind and dust, lights from traffic or squad car
  • Fear and nervousness, inner-ear problems
  • Age, injuries to the leg or knee, shoes and weight

If an attorney does not ask you about factors such as these, he or she may not know the science behind a successful DWI defense. Call Deandra for a full investigation of the defenses available to you. This is not the time to hire a less experienced attorney because he or she is a friend, the fees are low or you are too embarrassed to call another. We can meet with you at her Dallas or Plano office.

We handle a full range of DWI related matters in Texas including:
