DUI Defenses In Arizona

Fighting your DUI Charge, and the Effect it has on your Life

dui defense attorney in phoenix arizonaThere are two layers to defending an Arizona DUI; first, we work to defend you from your charges. If there is any weakness in the DUI case against you, I will work to find the hole in the case and get the case dismissed. However, if the circumstances around your case leave no opening, I will continue to defend you and ensure that the penalties for your DUI have as little effect on your day to day life as possible.

Some of the Possible Defenses to a DUI Charge Include:

Whether or Not the Police Were Right to Pull You Over

One of the more commonly used defenses against a DUI charge is to challenge whether or not the police officer had the right to pull over your car in the first place. If I can get a judge to determine that the police did not have the right to pull you over, then whatever evidence resulted from the pullover cannot be used against you at trial and therefore in all likelihood the case will have to be dismissed. Just because a police officer thinks he had a legal reason to stop your vehicle does not mean a judge will agree. Minor swerving (within the lane, not crossing over any lines) or an anonymous tip about a drunken driver are two possible causes for pullover that could be challenged in court.

Police Video or Audio Recordings Which Contradict Police Testimony

I will work to obtain any available video, such as body camera or police vehicle dash camera or audio recordings to see if what the officers said about you and your actions is not true. For example if an office said you were slurring your speech the audio recording may show that is not true.

Breath & Blood Test Defenses

If there is an opportunity to call the BAC test into question, the DUI case against you can unravel very quickly. Some of the possible issues that can be raised around blood and breath testing include:

  • Breathalyzer License InvalidationAnyone who operates a Breath Testing machine for the police department needs to have a valid and current license, if not, the test can be invalid.
  • Breathalyzer Test MalfunctionedThe Police are required to keep detailed records about the operation and calibration of the breath test machines, which are known as the Intoxilyzer. I will review those records to see if the device has a history of not functioning properly. If there is a reason in the records to call the accuracy of the Intoxilyzer into question, I will find it and capitalize on it. In addition, even if the Intoxilyzer is working properly it has inherent limitations and so I may be able to show even if you tested over the limit, you actual alcohol level could have been under the limit. The Intoxilyzer is not perfect and just because it prints out a piece of paper saying you were over does not necessarily means you were.
  • Blood TestingMany police departments, such as the Chandler, Gilbert, Mesa and Phoenix Police Departments use blood testing for alcohol and drugs in DUI cases. Blood testing also has inherent inaccuracies and those can be used to show your alcohol level was lower than what the police claim it was. With testing for drugs, the testing can provide results which falsely show the presence of drugs. With all blood testing the police collect a second sample of the blood which we can have one of the best experts in Arizona independently test so we challenge what the police say are the test results. Just because the police blood results say you are guilty does not mean that is scientifically true!

Questions around Field Sobriety Testing

There are several field sobriety testing methods that have been proven to be relatively inaccurate, but are still used from time to time by police officers. If a field sobriety test (one legged stand, reciting the alphabet, touching your nose, staring at the pen) was used and the officer claims the results of those test show you were impaired often I can take those same results and use them to show a jury that you were not impaired.
