Challenging the Prosecutor's Evidence in Phoenix DUI Cases

Driving under the influence is based upon a person's blood alcohol concentration (BAC), which is most often determined either through a blood test or a breath test. In the case of a DUI where drug use is suspected, a urine test is usually the process. But though blood, breath and urine tests are important, a DUI charge is primarily based upon the person's perceived ability to operate a vehicle. If a person consumes any alcohol, no matter the amount, and their ability to drive is impaired, that person could be convicted of DUI.

There are many strategies that a highly trained and experienced lawyer could employ to challenge the evidence in a DUI case. As the BAC level is based upon the results of a breath or blood test, testing procedures, accuracy of specific units, or maintenance and calibration of the unit used in testing could be challenged. The equipment used to administer a breath test could be examined to determine if it was functioning properly, or if the law enforcement officer correctly administered the test. Roadside testing units are notoriously inaccurate, and subject to incorrect readings due to temperature and other factors. Larger units also fail, as can any testing equipment. Also, if it is found that the police did not actually have a valid reason to suspect you of impairment when they pulled you over, your case could be dismissed for an illegal police stop. Call today and your attorney will evaluate your case to find the errors and flaws, and is prepared to challenge every piece of evidence in your DUI case.
