Faults With DWI Tests

Every day, police and sheriff’s deputies in the Texas Hill Country stop drivers they believe are under the influence of alcohol. They usually order the motorists to perform a series of tests to determine the level of alcohol in their system. If an officer decides the person they pulled over has failed the tests, they arrest the individual on suspicion of DWI.

The secret about these tests is they are far from foolproof. Devices regularly fail and officers frequently make mistakes that can cost you your freedom, your ability to drive or both. At Danford Law Firm, PLLC, our attorney has practiced DWI law as a prosecutor and defense attorney for more than 25 years. As “The DWI Guy,” he knows the signs of an error in roadside test results and will fight to get those tests thrown out of court.

What Can Cause A Breath Test Device To Fail

Breath test devices that measure your blood alcohol level must be regularly calibrated. Failure to do so by the officer who administers the test on the road or at the police station later on will skew the results; this could make it appear you are over the legal limit of .08% when you are not.

The Problem With Field Sobriety Tests

Field sobriety tests like the walk-and-turn test and the one-leg stand are supposed to detect whether your balance, reflexes and judgment are impaired by alcohol. However, these tests rely on the officer’s judgment. If your officer is inexperienced or their judgment is compromised, they could misinterpret the results and wrongfully arrest you. In addition, such tests often fail to take into account weather conditions or if the subject has a disability that makes walking in a straight line or standing on one foot difficult.

Taking Action Against Police Errors

We will investigate the circumstances of your arrest and determine if the testing was flawed. If it was, we will work doggedly to get the court to throw out the test results. Often, these roadside tests are the sole evidence against DWI defendants, so successfully suppressing bad field sobriety tests can lead directly to your charges getting dropped.
