Challenging the Traffic Stop – The first step in many DUI cases is analyzing the legality of the traffic stop. Law enforcement must have reasonable suspicion to pull you over. If this standard was not met, we will file a motion to suppress any evidence obtained during the stop, which can lead to your case being dismissed.

Improper Field Sobriety Testing – Field sobriety tests such as walking in a straight line or standing on one leg can be unreliable, especially if administered incorrectly or under unfavorable conditions like poor lighting, uneven surfaces, or bad weather. Fatigue, nervousness, and medical conditions can also affect performance. We investigate whether the officer was properly trained and certified to administer these tests.

Lack of Probable Cause for Arrest – Police officers must have a good reason to believe someone is breaking the law before they can make an arrest. In a DUI case, the officer must see signs that the driver is impaired in addition to swerving, slurred speech, or the smell of alcohol. If the officer didn’t have enough evidence to arrest you, Tamou Law Group will argue that the arrest was not legal — which can result in the case being dismissed.

Violation of Miranda Rights – Under Arizona DUI laws, if a driver is arrested and questioned without being read their Miranda rights, the defense can argue that any statements made during the interrogation are inadmissible in court. This can significantly weaken the prosecution’s case when any statements would be used to help prove impairment.

Faulty BAC Testing – Breathalyzer and blood tests are not perfect. If there were issues with the administration of the test or if the testing equipment was not properly calibrated, the accuracy of the BAC results can be called into question. Arizona DUI laws require that testing equipment be regularly maintained and properly administered. Tamou Law Group requests all maintenance records and evaluates whether proper procedures were followed.

Blood Sample Issues – For cases where blood samples were taken, the prosecution must be able to prove that the sample was properly handled and stored throughout the testing process. If there is any break in the chain of custody, the defense can argue that the results may have been tampered with or are otherwise unreliable. Tamou Law Group is equipped to analyze the blood results and chain of custody.

Rising BAC Defense – Your BAC may have been below .08 while driving but rose above the limit by the time testing occurred. Alcohol absorption takes time, and we use expert toxicologists to demonstrate your BAC at the time of actual driving was legal — not the BAC at the time of testing.

Medical Conditions – Certain medical conditions, such as diabetes or acid reflux, can lead to falsely elevated BAC results. Individuals with these conditions may have high levels of acetone in their breath, which can be mistaken for alcohol by a breathalyzer. This defense can be effective in cases where the BAC reading doesn’t match the driver’s level of impairment.

Let me guess? Your Implied Consent form states that the officer made observations like “bloodshot, watery eyes,” “odor of alcohol,” or “slurred speech” to justify further testing and arrest.

This is standard for them to say, but they need more!

The Admin Per Se / Implied Consent Affidavit is a form completed by the arresting officer and sent to the Arizona Department of Transportation (ADOT) Motor Vehicle Division (MVD). It serves as both the officer’s probable cause statement and the trigger for your administrative license suspension. The observations on this form — bloodshot eyes, odor of alcohol, slurred speech — are cookie-cutter phrases that officers use in nearly every DUI arrest. They are not proof of impairment.

1Request the MVD Hearing Within 15 Days – This is the most critical deadline in any DUI case. If you do not request an administrative hearing within 15 days of your arrest, your license will be automatically suspended. Tamou Law Group files this request immediately upon retention.

2Challenge the Officer’s Observations – The cookie-cutter language on the Implied Consent form is often unsupported by body cam footage. We compare the officer’s written observations against the actual video evidence to expose exaggerations and inconsistencies.

3Challenge the Testing Procedures – We examine whether the blood draw or breathalyzer test was conducted properly, whether the officer followed Arizona’s implied consent advisement requirements, and whether the BAC results are reliable enough to support a suspension.

4Win the Hearing or Secure Restricted Driving – If we win the MVD hearing, your license suspension is overturned entirely. If the suspension stands, we fight for a restricted license with ignition interlock so you can continue driving to work, school, and medical appointments.

1Be Polite But Say Nothing – Provide your license, registration, and insurance. Beyond that, politely decline to answer questions about where you were, how much you drank, or when your last drink was.

2Request an Attorney – Clearly state “I want a lawyer” before submitting to any chemical testing. Arizona’s implied consent law requires testing, but you have the right to counsel first.

3Request the MVD Hearing Within 15 Days – You must request an administrative hearing with the MVD within 15 days of your arrest or your license will be automatically suspended. A DUI lawyer can handle this immediately.

4Document Everything – Write down arrest details, officer names, badge numbers, what tests were performed, and the timeline of events while memory is fresh. This information helps build your defense.
