How to Beat a DUI in Arizona – A Break Down
1
Challenging the Traffic Stop
One of the most critical steps in defending a DUI is analyzing the legality of the traffic stop. Law enforcement must have reasonable suspicion to pull you over. If this standard wasn’t met, evidence obtained during the stop could be suppressed. For example, if your implied consent form only mentions subjective observations like “bloodshot eyes” or “slurred speech,” our attorneys challenge whether this was sufficient to warrant further testing or an arrest.
2
How to Beat a DUI in Arizona Using Improper Field Sobriety Testing
Field sobriety tests, such as walking in a straight line or balancing on one leg, are notoriously unreliable. Unfavorable conditions like poor lighting, uneven surfaces, or weather can lead to inaccurate results. Moreover, fatigue, medical conditions, or even nerves can affect performance. If the officer conducting the test wasn’t certified or failed to follow proper procedures, we aggressively argue that the results should be thrown out. Â
3
How to Beat a DUI in Arizona with Faulty BAC Testing
Breathalyzer and blood alcohol concentration (BAC) tests are not infallible. Faulty equipment, improper calibration, or procedural errors can lead to incorrect readings. Arizona law requires that all testing equipment be regularly maintained. At Tamou Law Group, we demand maintenance records and analyze whether your test was administered according to state protocols.
4
How to Beat a DUI in Arizona Using Medical Conditions and False BAC Readings
Certain medical conditions, such as diabetes or acid reflux, can cause false BAC readings. For instance, individuals with diabetes may have high acetone levels in their breath, which some breathalyzers misinterpret as alcohol. Our team meticulously examines your health history to ensure that medical conditions are factored into your defense.
5
How to Beat a DUI in Arizona Due to Lack of Probable Cause
Law enforcement must have probable cause to make an arrest. If the officer lacked sufficient evidence of impairment, beyond swerving or an alleged odor of alcohol, we challenge the legality of the arrest. A lack of probable cause can be grounds for case dismissal.
6
How to Beat a DUI in Arizona Due to Violation of Miranda Rights
If you were questioned after being arrested without being read your Miranda rights, any statements you made may be inadmissible. This can significantly weaken the prosecution’s case. We carefully review all post-arrest procedures to identify any violations of your rights.
7
How to Beat a DUI in Arizona Due to Blood Sample Chain of Custody Issues
If your blood was drawn for testing, the prosecution must prove that the sample was properly stored and handled. Any break in the chain of custody can cast doubt on the validity of the test results. We scrutinize every step of the process to ensure the evidence against you is airtight, or challenge it when it’s not.

Frequently Asked Questions
Can a DUI charge be dismissed in Arizona?
Yes, a DUI charge can be dismissed in Arizona when the defense proves the traffic stop lacked reasonable suspicion, the arrest lacked probable cause, or the breath or blood test was unreliable. Suppressing illegally obtained evidence often leaves prosecutors without a provable case, forcing dismissal or reduced charges.
Is an extreme DUI a felony in Arizona?
No, an extreme DUI with a blood alcohol concentration of 0.15 to 0.199 is a class 1 misdemeanor under A.R.S. 28-1382, not a felony. It becomes felony aggravated DUI under A.R.S. 28-1383 only when factors like a suspended license or a third offense within 84 months apply.
What is a super extreme DUI in Arizona?
A super extreme DUI in Arizona is driving with a blood alcohol concentration of 0.20 or higher, charged under A.R.S. 28-1382(A)(2). A first conviction carries a minimum of 45 days in jail, fines and fees exceeding $3,200, an 18-month ignition interlock requirement, and a 90-day license suspension.
What turns a DUI into an aggravated felony in Arizona?
A DUI becomes felony aggravated DUI under A.R.S. 28-1383 when committed on a suspended or revoked license, as a third DUI within 84 months, with a passenger under 15, while driving the wrong way, or while an ignition interlock order is in effect. Most aggravated DUIs are class 4 felonies carrying mandatory prison time.
How much does a DUI lawyer cost in Arizona?
A DUI lawyer in Arizona typically costs between $2,500 and $10,000, depending on whether the charge is a first-offense misdemeanor or a felony aggravated DUI headed to trial. Given that convictions carry mandatory jail, fines, and license loss, experienced defense counsel often saves far more than it costs.
Does diabetes or acid reflux cause a false breathalyzer reading in an Arizona DUI?
Yes, medical conditions like diabetes, GERD, and acid reflux can cause falsely high breathalyzer readings. Diabetics can produce acetone that some devices misread as alcohol, while reflux pushes mouth alcohol into the breath sample. Arizona DUI attorneys use medical records and expert testimony to challenge these unreliable results.
How long does a DUI stay on your record in Arizona?
A DUI conviction stays on your Arizona criminal record permanently, though it counts as a prior offense for sentencing enhancement only for 84 months, or seven years. Arizona does not allow full expungement, but you may petition to have the conviction set aside under A.R.S. 13-905 after completing your sentence.
What should I do first after a DUI arrest in Arizona?
Contact a DUI defense attorney immediately and request an MVD hearing within 15 days of your arrest to contest your automatic license suspension under A.R.S. 28-1385. Acting fast preserves evidence like body-camera footage and calibration records that can win your case. Call 623-321-4699, 24/7.
