Breathalyzer & Blood Tests for DWI

Challenging Potentially Faulty Results in Dallas, Collin & Tarrant Counties

The law dictates that those with a blood alcohol level above .08 are incapable of driving safely. Serving as the legal definition of “drunk,” the law per se assumes your incapability when your BAC reaches this level. However, this number is ultimately arbitrary—it was chosen because it “works” for most of the population, but it is no guarantee of drunkenness. Natural, medical, or technological flukes can cause inaccurate readings.

At Crain Lewis Brogdon, LLP, we challenge the results of breathalyzer and blood tests on behalf of our clients. There are enough equipment flaws and variations in human body chemistry to raise doubts about your results, and our effective defense strategies root out every possible cause behind your result to cast doubt on your accusations. Whether you refused to take your test or failed a test on an Intoxilyzer 5000, we have the experience to defend your rights.

Questions to Ask About Every Breathalyzer Result

Regardless of your results, Crain Lewis Brogdon, LLP believes you have the right to skilled and effective Dallas DWI attorneys. There are several different reasons why you may have failed a breath test—some are medical, and some are rooted in administrative mistakes. For some people, their BAC reading may not actually indicate how drunk they are because their breath does not reveal alcohol levels the way the machine assumes it does.

For example, BAC measures the concentration of alcohol in your blood per unit in grams of alcohol per deciliter. However, breath tests do not measure BAC directly—they measure the alcohol in your breath, assuming a uniform ratio between blood and breath for all test-takers. However, many people have different partition ratios between their breath and blood, making many test results inaccurate.

Other ways we challenge BAC readings is by asking the following:

  • Was the blood test administered correctly?
  • Was the breath test administered correctly?
  • Is there a medical condition that caused the test to read inaccurately?

Do not let your test results remain unchallenged—call (214) 301-5007 for a free consultation with a Dallas DWI lawyer.
