Common DUI Defenses in Arizona

Lack of Reasonable Suspicion for the Stop

Police officers must have a valid reason to pull you over, such as a traffic violation or observable impairment. If the stop was unlawful, evidence gathered afterward may be suppressed.

Unlawful Arrest or Lack of Probable Cause

Even after a lawful stop, police must have probable cause before making an arrest. If the officer lacked sufficient grounds, the arrest itself may be challenged.

Breath or Blood Test Errors

Breathalyzers and blood testing equipment must be maintained, calibrated, and operated correctly. Errors in testing or mishandling of blood samples can make results unreliable.

Field Sobriety Test Issues

Field sobriety tests are subjective and often administered under poor conditions. Factors like fatigue, medical issues, or uneven surfaces can lead to inaccurate results.

Rising Blood Alcohol Defense

Alcohol takes time to absorb into the bloodstream. It’s possible your BAC was below the legal limit while driving, only rising afterward when the test was given.

Medical Conditions or Prescription Medications

Certain medical conditions, such as acid reflux or diabetes, and some lawful medications, can create false positives in DUI testing.

Violation of Constitutional Rights

Improper searches, failure to read Miranda rights, or other constitutional violations can lead to suppression of evidence.

Building a DUI Defense in Arizona

Arizona has some of the strictest DUI laws in the country, with mandatory jail time, fines, license suspension, and ignition interlock requirements. The prosecutor will move quickly, which is why it’s critical to have a defense strategy in place as soon as possible.

At Damianakos Law, we examine every aspect of your case, including:

• Whether the officer followed proper procedures during the stop and arrest
• The reliability of breath, blood, and field sobriety tests
• Any violations of your constitutional rights
• The possibility of alternative explanations for test results

Our job is to find weaknesses in the prosecution’s case and use them to protect your record, your license, and your freedom.
