Actual Physical Control DUI in Arizona — How courts decide APC and when cases can be won
In Arizona, “actual physical control” (APC) for DUI means you can be convicted under A.R.S. § 28-1381 for being in control of a vehicle while impaired, even if you weren’t driving. Courts apply a totality-of-the-circumstances test from State v. Love and State v. Zaragoza to assess immediate driving risk.
What APC means in Arizona
Arizona’s DUI statute, A.R.S. § 28-1381, makes it unlawful to “drive or be in actual physical control” of a vehicle while impaired to the slightest degree by alcohol or drugs, or with a blood alcohol concentration (BAC) of 0.08 or more within two hours. The phrase “actual physical control” (APC) allows the state to prosecute individuals who are not observed driving but are found in circumstances suggesting an immediate ability to operate a vehicle while impaired.
APC is not defined by statute. Instead, Arizona courts interpret it under a totality-of-the-circumstances standard. The Arizona Supreme Court in State v. Love, 182 Ariz. 324 (1995), shifted the focus away from rigid rules and toward whether the person posed a real danger of driving. Later, in State v. Zaragoza, 221 Ariz. 49 (2009), the Court approved a jury instruction listing specific factors to evaluate APC, emphasizing whether the defendant’s impaired state presented a present or imminent risk of putting the vehicle in motion.
Practically, an impaired person asleep in a running car in a travel lane likely presents APC. By contrast, a sleeping person parked legally with the engine off, keys out of reach, and clear signs of using the car as a temporary shelter may not be in APC under Love and Zaragoza. Each case turns on concrete, provable facts and how they relate to immediate driving risk.
Key factors & cases that decide APC
Courts and juries weigh many facts to decide APC. Zaragoza approves considering:
– Whether the engine was running or ignition on
– Where the keys were and whether they were readily accessible
– The driver’s position (driver’s seat vs. back seat) and whether a seatbelt was on
– Gear selection, parking brake, headlights, and vehicle operability
– Vehicle location (travel lane, shoulder, parking lot) and time of day
– Whether the driver voluntarily pulled off the roadway
– Weather conditions and the need for heat or AC for safety
– The person’s intent and steps taken to avoid driving
Love underscores that there is no single controlling factor; the ultimate question is whether the defendant’s impaired control of the vehicle presented a real danger of immediate driving. In many Phoenix, Tempe, Scottsdale, or Mesa prosecutions, cases turn on small details: a key in the ignition, a foot on the brake, the vehicle in “drive,” or the car straddling a lane line. Conversely, evidence showing the driver deliberately made the car inoperable or used it as a safe shelter can defeat APC.
Arizona’s “two-hour rule” also matters. Under A.R.S. § 28-1381(A)(2), the state may prove your BAC was 0.08+ within two hours of “driving or being in actual physical control,” so the timeline of when you drank and when you were found is critical evidence at trial.
Statutes, penalties & court process
Key statutes:
– A.R.S. § 28-1381(A)(1): Impaired to the slightest degree while driving or in APC.
– A.R.S. § 28-1381(A)(2): BAC 0.08+ within two hours of driving or being in APC.
– A.R.S. § 28-1381(A)(3): Any drug or its metabolite while driving or in APC.
– A.R.S. § 28-1382: Extreme (0.15–0.199) and super extreme (0.20+).
– A.R.S. § 28-1383: Aggravated DUI (e.g., license suspended, third offense in 84 months, minor in the vehicle, or ignition interlock violation).
– A.R.S. § 28-3319: Ignition interlock requirements after conviction.
Penalties overview:
– Regular DUI (A.R.S. § 28-1381) is a Class 1 misdemeanor. Statutory minimum jail is 10 days; courts may suspend a portion upon completion of alcohol or drug screening and treatment as permitted by statute. Fines, assessments, education, and community service may be ordered. License consequences flow through MVD, and ignition interlock is typically required under § 28-3319.
– Extreme and super extreme DUIs (A.R.S. § 28-1382) carry higher mandatory jail terms, larger fines, longer interlock, and additional conditions.
– Aggravated DUI (A.R.S. § 28-1383) is a felony, prosecuted in Superior Court, with prison exposure and substantial collateral consequences.
Court process in Arizona:
– Stop/investigation: Officers evaluate driving behavior, physical signs, field sobriety tests, and request breath or blood testing. APC arrests often start as welfare checks on stopped vehicles.
– MVD action: If served an Admin Per Se or Implied Consent notice, you generally have 15 days to request a hearing with ADOT’s Executive Hearing Office to challenge a suspension. Missing this deadline can trigger automatic license consequences independent of the criminal case.
– Arraignment & pretrial: Misdemeanor APC DUIs are typically filed in municipal or justice courts (e.g., Phoenix Municipal Court, Tempe Municipal Court, Scottsdale City Court, Mesa Municipal Court, or Maricopa County Justice Courts). Felony aggravated cases are filed in Maricopa County Superior Court. Discovery proceeds under Rule 15, Ariz. R. Crim. P. Pretrial motions, including suppression, are heard under the criminal rules.
– Trial & sentencing: DUI defendants are jury-eligible; misdemeanor trials are generally before a six-person jury. If convicted, the court imposes statutory minimums and any enhancements that apply; the MVD separately administers interlock and license actions.

Defenses & evidence in APC DUIs
No actual physical control: Using the Zaragoza factors, the defense can show you took steps to avoid driving and posed no imminent driving risk. Examples include parking legally off the roadway, turning the engine off, placing keys out of reach, moving to the back seat, arranging a ride, or waiting for a sober driver.
Unlawful stop or detention: Many APC cases begin as welfare checks. Evidence may be suppressed if an initially valid welfare check turns into a detention without reasonable suspicion, or if the investigation exceeded its lawful scope. Suppression of statements or chemical tests can collapse the state’s case.
Two-hour rule & timeline: The state must prove impairment or a prohibited BAC within two hours of driving or APC. When drinking occurred after parking, or when the state’s timeline is unclear, expert testimony on alcohol absorption/elimination and careful documentation (receipts, texts, surveillance, witnesses) can defeat the “within two hours” element under § 28-1381(A)(2).
Chemical test reliability: Breath and blood evidence must meet scientific and regulatory standards. The defense examines instrument calibration and records, sample collection, chain of custody, anticoagulants/preservatives, lab method validation (e.g., gas chromatography), potential contamination, and reporting accuracy.
Mitigation & sentencing relief: Early alcohol/drug screening and treatment can position you for suspended jail under § 28-1381’s sentencing scheme. Demonstrating responsible steps taken after the incident can influence plea negotiations and sentencing outcomes in city and justice courts.
Lawyer experience matters: Derek Oliverson is a former police officer, Arizona prosecutor, and city court judge who presided over high-volume misdemeanor dockets; David Tangren is a former Pima County prosecutor. That perspective informs case strategy, motion practice, and how juries view APC evidence.
Where APC cases are heard
Misdemeanor APC DUI charges in Maricopa County are commonly filed in Phoenix Municipal Court, Tempe Municipal Court, Scottsdale City Court, Mesa Municipal Court, and the Maricopa County Justice Courts serving the location of the stop. Felony aggravated DUI cases proceed in Maricopa County Superior Court.
Because APC turns on local enforcement practices and courtroom procedures, venue matters. Policies for disclosure, motion settings, and trial readiness can differ between municipal and justice courts. If your case arose in Phoenix, Tempe, Scottsdale, or Mesa, local knowledge can impact how your Zaragoza factors are presented to a six-person jury.

What to do next
Protect your license within 15 days
If you received an Admin Per Se or Implied Consent notice, request an MVD hearing within 15 days or face an automatic suspension. We handle the filing and represent you before ADOT’s Executive Hearing Office to challenge the basis for suspension and the test’s lawfulness.
Preserve APC-friendly evidence
Document where the car was parked, whether the engine was off, key location, and any efforts to avoid driving (ride-share receipts, texts, witnesses, store videos). These facts directly address Zaragoza’s totality test and can be the difference between conviction and acquittal.
Assess the timeline and testing
Pin down when any drinking occurred relative to when you parked or slept, and obtain calibration logs, blood records, and officer body-cam. A strong timeline and scientific review can undermine the “within two hours” element and the reliability of chemical results.

Common mistakes to avoid
Frequently Asked Questions
Yes, if the facts show you were in actual physical control. Arizona applies a totality-of-the-circumstances test from State v. Love and State v. Zaragoza. Risk factors include a running engine, keys in the ignition, sitting in the driver’s seat, and vehicle position. Safer facts include parking legally, turning the engine off, placing keys out of reach, and using the back seat.
Regular misdemeanor APC DUIs are filed in municipal or justice courts (for example, Phoenix Municipal Court, Tempe Municipal Court, Scottsdale City Court, Mesa Municipal Court, or Maricopa County Justice Courts). Aggravated DUI felonies are filed in Maricopa County Superior Court. Venue typically depends on where the stop or contact occurred and the charging agency’s jurisdiction.
The state may prove your BAC was 0.08 or more within two hours of driving or being in actual physical control. The exact timeline is critical. If drinking occurred after you parked or if the state cannot establish times reliably, the two-hour element can fail. Evidence like receipts, surveillance, texts, and witnesses becomes vital.
Common defenses include: no actual physical control under Zaragoza’s factors, unlawful stop or prolonged detention, unreliable breath or blood testing, and failure to prove the two-hour element. Mitigation, like early screening and treatment, can reduce jail exposure under the statutory scheme even when a conviction risk remains.
