How a DUI Defense Attorney Uses Pretrial Interviews to Build Your Defense


If you've been charged with a DUI in Tucson, Arizona, you’re probably feeling overwhelmed and wondering how your case will be handled. One crucial part of the defense process that often gets overlooked is the pretrial interview. This step is where your DUI defense attorney carefully examines the evidence and testimony against you to build a strong defense.

As an experienced DUI defense attorney in Tucson, Arizona, I know how critical this phase can be in shaping the outcome of a case. Here's an inside look at how pretrial interviews work and why they’re a powerful tool in defending you.

What Is a Pretrial Interview?

In Arizona, the defense has the right to conduct interviews with the prosecution’s witnesses before trial. These interviews are typically done with police officers, forensic experts, or other individuals who have provided evidence or testimony against you.

The purpose of a pretrial interview is simple: to gather information, identify weaknesses in the prosecution’s case, and prepare a strategy for trial or negotiations.

How Pretrial Interviews Help Your DUI Defense

1. Understanding the Officer’s Training and Experience

One of the first steps in any DUI case is examining the training and qualifications of the arresting officer. During the pretrial interview, your attorney will ask questions like:

  • What DUI-related training has the officer completed?

  • Are they certified to conduct standardized field sobriety tests (SFSTs)?

  • How experienced are they in handling DUI investigations?

By evaluating the officer’s knowledge and experience, your attorney can determine if mistakes were made during your stop, field sobriety tests, or arrest.

2. Challenging Field Sobriety Test Procedures

Field sobriety tests are often a cornerstone of DUI cases, but they’re not foolproof. During the pretrial interview, your attorney will explore:

  • Whether the tests were administered according to proper protocols.

  • Environmental factors (e.g., uneven ground, poor lighting) that could have affected the results.

  • The officer’s ability to interpret the signs of impairment accurately.

This information can be used to argue that the test results are unreliable and shouldn’t be used against you in court.

3. Exposing Gaps in the Evidence

Your attorney will use the pretrial interview to uncover any weaknesses in the State’s evidence. This includes asking questions about:

  • The calibration and maintenance of breathalyzer devices.

  • The chain of custody for blood or urine samples.

  • Any inconsistencies between the officer’s report and their testimony.

These gaps can be critical in creating reasonable doubt in your case.

4. Locking in the Officer’s Testimony

Pretrial interviews allow your attorney to "lock in" the officer’s version of events. This means getting the officer to commit to specific details about the stop, arrest, and evidence collection. If their testimony changes at trial, your attorney can use the pretrial interview transcript to challenge their credibility.

5. Building a Narrative That Supports Your Defense

Your attorney will also use the pretrial interview to gather facts that align with your version of events. For example:

  • Did the officer observe actual unsafe driving, or were they relying on minor infractions like driving under the speed limit?

  • Were there medical or non-alcohol-related explanations for your behavior or appearance?

This process helps build a defense narrative that focuses on alternative explanations for the evidence against you.

Why Pretrial Interviews Aren’t About Confrontation

It’s important to note that pretrial interviews are not about arguing with the officer or trying to "catch them" in a lie. Instead, the goal is to gather information and understand the strengths and weaknesses of the prosecution’s case. Confrontation or "gotcha" tactics are better reserved for trial when they can make a stronger impact in front of a judge or jury.

How a DUI Defense Attorney Uses This Information to Win

Once the pretrial interviews are complete, your attorney will use the information gathered to:

  • File motions to suppress improperly obtained evidence.

  • Negotiate with the prosecutor for reduced charges or a dismissal.

  • Prepare for trial with a clear strategy to challenge the State’s evidence and witnesses.

Every piece of information gained during the interview is another step toward creating a robust defense.
