DUI Defense Strategies: How to Fight a DUI Charge in Arizona

Feb 14 2025

If you’ve been arrested for a DUI in Arizona, you may be wondering what legal defenses could help you fight the charges. Every DUI case is unique, and the right defense strategy depends on the specifics of your situation. A strong legal defense can potentially lead to reduced charges or even a case dismissal.

Understanding Arizona DUI Defense Strategies

A successful DUI defense starts with a thorough review of all available evidence. Attorney Joshua A. Lopez will analyze key discovery materials, such as:

  • Police reports
  • Dashcam and bodycam footage
  • Surveillance videos
  • Blood and breath test results
  • Calibration and maintenance records for breathalyzers

Identifying weaknesses in the prosecution’s case can be critical in fighting a DUI charge.

What Are the Best DUI Defenses in Arizona?

Several legal defenses may apply to your case, including:

1. Lack of Reasonable Suspicion for the Stop

Law enforcement must have a valid reason to pull you over. If the officer did not have reasonable suspicion, any evidence obtained during the stop may be inadmissible.

2. Lack of Probable Cause for the Arrest

Even if the initial stop was legal, officers must have probable cause to arrest you for DUI. If probable cause is lacking, your arrest could be challenged in court.

3. Faulty or Inaccurate Testing Equipment

Breathalyzers and other chemical testing devices must be properly calibrated and maintained. If there are errors in testing equipment, your results may be unreliable and subject to dismissal.

4. Errors in Field Sobriety Testing

Field sobriety tests must be administered correctly by qualified officers. If the tests were improperly conducted, their results may be challenged in court.

5. No Evidence of Actual Physical Control or Driving

In some cases, the prosecution may not have clear evidence that you were driving under the influence. If there is no proof of actual physical control of the vehicle, this can serve as a strong defense.
