Tempe DUI Lawyer Proven Defense
Former Felony Prosecutor | 23 Years Trial Experience
When you face DUI charges in Tempe—whether arrested on Mill Avenue during a night out, near ASU campus after a tailgate, or on your way home along the Loop 202—you need proven defense built on insider prosecutorial knowledge. Jeremy Huss spent over a decade as a felony prosecutor, training Arizona law enforcement agencies on DUI investigation protocols, chemical testing procedures, and courtroom testimony standards. Today, he applies that 23-year trial record to defend drivers throughout Maricopa County against the aggressive DUI enforcement Tempe deploys around its entertainment districts and university neighborhoods.
A DUI arrest triggers two separate legal battles: the criminal case in Tempe Municipal Court and the administrative license suspension through Arizona’s Motor Vehicle Division. Both demand immediate action. Miss the 30-day MVD hearing deadline, and your driving privilege disappears automatically on day 31—regardless of guilt or innocence.

Arizona DUI Offense Categories
Standard DUI – A.R.S. § 28-1381
Subsection (A)(1) – Impaired to the Slightest Degree Driving while impaired by alcohol, drugs, vapor-releasing substances, or any combination thereof to even the slightest degree. No specific BAC level required—prosecution relies on officer observations, field sobriety test performance, and driving pattern evidence.
Subsection (A)(2) – Per Se DUI BAC of 0.08% or higher within two hours of driving or being in actual physical control of the vehicle. The timing window matters: if you register 0.08% ninety minutes after your stop, you face charges even if your BAC was lower while actually driving.
Extreme DUI – A.R.S. § 28-1382
BAC between 0.15% and 0.199%
- Mandatory minimum: 30 consecutive days incarceration
- 21 days suspended if defendant completes alcohol screening and treatment
- Increased fines and assessment costs
- Extended ignition interlock requirement
Super Extreme DUI – BAC of 0.20% or higher
- Mandatory minimum: 45 consecutive days incarceration
- 31 days suspended with treatment completion
- Substantially higher fines and costs
- Longer ignition interlock period
The DPS annual report cited earlier shows Arizona’s average extreme DUI arrest involves a 0.157% BAC —just above the extreme threshold but below super extreme. This concentration in the 0.15-0.19 range creates significant litigation opportunities around breath test accuracy, observation period compliance, and rising BAC defenses.
Drug and Cannabis DUI – A.R.S. § 28-1381(A)(3)
Driving while any drug defined in A.R.S. § 13-3401 or its metabolite is present in the driver’s body creates potential DUI liability. However, Arizona law changed significantly following Proposition 207’s legalization of adult-use marijuana in 2020.
Critical distinction for marijuana cases: Since Proposition 207, drivers cannot be prosecuted for marijuana metabolites in their system. The state must prove more than the presence of active THC (delta-9-tetrahydrocannabinol). That alone would never convict a driver. The State must prove beyond a reasonable doubt that the marijuana “impaired” the driver. This distinction creates substantial defense opportunities in cannabis DUI cases, and makes marijuana DUI cases in Arizona difficult for the State to meet its burden.
For other controlled substances listed in A.R.S. § 13-3401, the per se rule still applies—mere presence of the drug or its metabolite establishes the violation without requiring proof of actual impairment.
Drug DUI cases demand scientific expertise in blood testing methodology, laboratory procedures, and the pharmacology of how different substances affect the body. Our dedicated Arizona Cannabis DUI Lawyer page provides comprehensive analysis of defense strategies specific to marijuana charges.
Aggravated (Felony) DUI – A.R.S. § 28-1383
Misdemeanor DUI becomes a Class 4, 5, or 6 felony when aggravating factors exist:
- Third DUI within 84 months (7 years)
- Driving on a suspended, revoked, or restricted license for a prior DUI
- Passenger under 15 years old present in vehicle
- Required ignition interlock device installed but not used
- Wrong-way driving on a highway or freeway
Felony DUI cases transfer from Tempe Municipal Court to Maricopa County Superior Court and carry potential prison sentences ranging from probation to 3.75 years incarceration for first-time felony offenders without aggravating circumstances. In fact, even probation guarantees may carry a minimum of 4 months prison as a term of probation for certain Class 4 Felony Aggravated DUIs (i.e., (1) Driving with license suspended; (2) 3rd or more DUI within the past 84 months; and (3) Driving down the wrong side of a highway). Only the offenses of Aggravated DUI with a Minor under 15 years old (Class 6 Felony) and Aggravated DUI with an Ignition Interlock Device Required (Class 4 Felony) do not require the minimum 4 months prison as a term of probation, but they still require some incarceration. And if it is a second offense misdemeanor or felony it is significant incarceration.
Our When Is a DUI a Felony in Arizona? resource explains felony DUI thoroughly, including sentencing grids and defense approaches.
From Traffic Stop to Courtroom
- Traffic Stop & Field Investigation: Officers must have reasonable suspicion to initiate stop. Field tests are voluntary and easily disputed.
- Chemical Testing: Breath or blood testing under implied consent law. Refusal triggers automatic 1-year suspension.
- Parallel Proceedings: Criminal case in Tempe Municipal Court and MVD administrative hearing proceed independently.
“It is extremely important for a person to remember to (1) Not say a word to the police other than your true name and provide the required paperwork; (2) REFUSE Field Sobriety Tests; and (3) REFUSE the Portable Breath test (the hand-held breath test at the roadside).”
Mandatory Minimum Penalties for First-Offense DUI

| Super Extreme DUI (BAC .20+) | 45 days consecutive (31 suspended with alcohol screening) | $3,000–$3,800 | 90 days (eligible for restricted permit after 30 days) | 18 months | Alcohol screening, treatment if ordered, traffic survival school, community service |
Additional Financial Consequences:
- DUI evaluation and screening: $200–$500

- License reinstatement fees: $50–$250
- Traffic survival school: $300–$400
Total first-offense DUI costs typically range from $8,000 to $15,000 when accounting for all direct and indirect expenses over the conviction period.
Former Prosecutor Defense Strategy
As a former felony prosecutor who trained law enforcement agencies statewide on DUI investigation and trial testimony, I evaluate your case using the same framework prosecutors employ—then identify every weakness, inconsistency, and constitutional violation they hope you won’t challenge.
- Traffic Stop Legality: Challenge reasonable suspicion and probable cause. If the initial stop fails constitutional scrutiny, every piece of evidence afterward becomes inadmissible.
- Chemical Test Accuracy: Examine Intoxilyzer records, lab chain of custody, observation period violations, and machine maintenance logs to identify protocol errors.
- Officer Credibility: Compare police reports against body cam video for contradictions, template language, and claimed observations not visible on footage.

Common Questions From Tempe DUI Clients
How long does a Tempe DUI case typically take to resolve?
Most first-offense misdemeanor DUI cases resolve within 3-6 months from arrest through pretrial conferences and negotiation. Cases involving suppression motions, blood test challenges, or jury trial demands extend to 6-12 months. Felony DUI cases in Superior Court typically require 8-15 months due to grand jury proceedings, complex discovery, and felony trial preparation timelines.
Where will my case be heard?
Misdemeanor DUI charges are prosecuted in Tempe Municipal Court , located at 140 East 5th Street, Tempe, AZ 85281. Felony DUI charges transfer to Maricopa County Superior Court at the Southeast Facility (222 East Javelina Avenue, Mesa) or Central Court Building (201 West Jefferson Street, Phoenix) depending on assignment.
What happens if I miss the 30-day MVD deadline?
Your license suspension becomes automatic and unavoidable. You lose the opportunity to challenge the suspension through an administrative hearing and cannot obtain a restricted permit until after serving the mandatory minimum suspension period. This compounds the hardship of your criminal case, as you’ll face transportation challenges for court appearances, alcohol screening appointments, and employment obligations throughout case resolution.
Will I definitely go to jail if convicted?
Arizona mandates minimum incarceration periods for DUI convictions: 10 days for standard DUI, 30 days for extreme, 45 days for super extreme. However, statutes allow judges to suspend most of this time if you complete alcohol screening and comply with all other conditions. First-time standard DUI defendants typically serve 1 actual day in custody (24 consecutive hours), with the remaining 9 days suspended. Work release, home detention, and continuous alcohol monitoring programs may substitute for traditional incarceration depending on your employment situation, judge assignment, and case specifics.
Does a DUI affect my insurance rates?
Yes, substantially. Arizona insurance companies classify DUI convictions as major violations triggering high-risk SR-22 filings. Average premium increases range from $3,000-$5,000 annually for three years following conviction. Some insurers cancel policies entirely upon DUI conviction, forcing you into the assigned-risk pool with even higher rates. Total insurance cost increase over three years: $9,000-$15,000 beyond normal premium growth.
Can I get my DUI record expunged in Arizona?
Arizona does not offer expungement (record deletion) for DUI convictions. However, A.R.S. § 13-905 allows setting aside convictions after successfully completing all sentence terms. A set-aside releases you from penalties and disabilities but the conviction remains visible on background checks with a notation that it was set aside. This helps with employment applications but doesn’t restore a completely clean record. DUI convictions cannot be set aside while you’re required to maintain an ignition interlock device.
