DUI & Traffic Defense in Arizona

Strategic Advocacy Against DUI and Related Traffic Offenses

Whether challenged by breath tests, field sobriety stops, or traffic stops, Armour Legal contests procedure, evidence, and officer testimony to minimize or dismiss DUI and related charges.

Our aggressive challenge of test accuracy, stop protocols, and legal defenses secures reduced penalties or dismissal whenever possible.

What We Defend
Breathalyzer and blood-test reliability

Proper conduct of field-sobriety tests

Traffic-stop justification and search-and-seizure issues

Plea bargaining and diversion options

License suspension and hardship petition support

We defend impairment‑based DUI, per‑se DUI, extreme/super‑extreme categories, drug‑related DUI, and commercial‑driver DUI, as well as racing, reckless driving, and criminal speeding. We analyze stop justifications, field‑sobriety standards, breath calibration, and blood‑draw chains, and we represent clients at MVD/ADOT proceedings to protect licenses.


For clients with medical conditions or medication interactions, we present targeted medical explanations and expert input. Resolution tracks include charge reductions, treatment‑anchored outcomes, ignition‑interlock solutions, and carefully documented compliance to minimize collateral damage.

DUI & Traffic: Impairment, Per‑Se Limits & Procedure

DUI prosecutions proceed on two tracks: impairment‑based and per‑se (breath/blood over statutory limits). We attack the building blocks—stop justifications, field‑sobriety protocols, machine calibration, and blood‑draw chain of custody. Administrative license consequences run on a separate timeline, so we request MVD/ADOT hearings promptly to protect driving privileges.


For commercial drivers and under‑21 cases, the rules and consequences differ. We tailor defenses to medical conditions, mouth‑alcohol contamination, rising BAC, and improper observation periods. Where appropriate, we pursue reduced charges, ignition‑interlock alternatives, or treatment‑based resolutions.


Traffic crimes (racing, reckless driving, criminal speeding) can carry jail, points, and insurance spikes. Early intervention often reduces downstream employment and insurance fallout.

On-the-Go Defense: DUI & Traffic Offense Experts at Your Service

First-offense DUI (ARS §28-1381) carries license suspension, fines, and possible jail. Armour Legal contests breath-test calibration, field-sobriety-test protocols, and probable-cause determinations to suppress evidence.


We also defend against commercial-license (CDL) and under-21 DUI charges, coordinate DMV-hearing representation, and explore diversion-program eligibility to protect both criminal record and driving privileges.

DUI defense at Armour Legal is procedure‑driven. We analyze the stop, field‑sobriety administration, observation periods, breath calibration, and blood‑draw handling. We subpoena logs, certifications, and chain‑of‑custody documents, and we challenge rising‑BAC theories with timing and physiology. In parallel, we handle MVD/ADOT hearings to protect driving privileges.


For commercial drivers, under‑21 defendants, or clients with medical conditions, we tailor arguments and mitigation to the unique rules and risks. In traffic crimes—racing, reckless, criminal speeding—we pursue charge reductions that minimize jail, points, and insurance fallout, with a plan clients can follow from day one.

Frequently Asked Questions

Can I refuse a breathalyzer test?
You may refuse, but Arizona’s “implied consent” law carries administrative license suspension. We defend against both criminal DUI charges and DMV actions to preserve your driving privileges.
What penalties apply for a first-offense DUI?
First-offense DUI can result in fines up to $1,500, up to 6 months in jail, and a 90-day license suspension. We negotiate for diversion or reduced charges whenever possible.
How can I challenge a field-sobriety test?
Field tests rely on officer training and environmental factors. We scrutinize protocols, weather, and roadway conditions to challenge their validity in court.
What are the long-term consequences of a DUI?
Beyond fines and suspension, a DUI can raise insurance rates dramatically, impact employment background checks, and restrict international travel. We strive to minimize or avoid these through skilled defense.
