Actual physical control DUI in Arizona allows prosecutors to charge impaired individuals under ARS 28-1381 even when the vehicle never moved. The landmark decision in State v. Love, 182 Ariz. 324 (1995), established a totality of circumstances test that courts across Maricopa County apply to determine whether a person had present capability to operate the vehicle.

What Actual Physical Control Means Under ARS 28-1381
Arizona Revised Statutes section 28-1381 makes it unlawful to drive or be in actual physical control of a vehicle while under the influence of intoxicating liquor, drugs, or any combination that causes impairment to the slightest degree. The critical phrase is “actual physical control.” Unlike most states that require observed driving or vehicle movement, Arizona treats mere presence behind the wheel of a vehicle with access to the means of operation as equivalent to driving for DUI purposes.
The statute itself does not define what actual physical control means. That gap left courts to develop the standard through case law. Before 1995, Arizona applied a rigid mechanical test that focused almost exclusively on whether the keys were in the ignition and the engine was running. That approach produced harsh results for people who were trying to do the responsible thing by pulling over or sleeping in their car instead of driving while impaired.
The practical effect is that an Arizona officer who finds someone asleep in the driver’s seat of a parked car at 2 a.m. can arrest that person for DUI even if the car never moved an inch. The charge carries identical penalties to a standard driving DUI, including jail time, fines, license suspension, mandatory ignition interlock installation, and alcohol screening. Whether the charge sticks depends on how the facts align with the factors Arizona courts now evaluate under the totality of circumstances framework established in State v. Love.
Actual physical control charges are particularly common near entertainment districts in Scottsdale, Tempe, and downtown Phoenix where officers patrol parking lots and side streets during late-night hours. Someone who makes the decision to sleep it off in their vehicle rather than drive can still face arrest, booking, and prosecution under ARS 28-1381. Understanding how Arizona defines and prosecutes this offense is essential to mounting an effective defense.
The State v. Love Totality of Circumstances Test
The Arizona Supreme Court fundamentally reshaped actual physical control law in State v. Love, 182 Ariz. 324 (1995). Before this decision, courts relied on a bright-line test that treated anyone in the driver’s seat with keys accessible as being in actual physical control. The Love court rejected that rigid approach and adopted a totality of the circumstances test that examines multiple factors to determine whether the defendant posed a real danger of driving while impaired.
The Love decision held that actual physical control requires more than theoretical ability to operate the vehicle. Courts must examine whether the defendant had the present capability to put the vehicle in motion and whether the circumstances indicated an apparent intent to drive. The court emphasized that the purpose of the DUI statute is to deter intoxicated people from getting behind the wheel, not to penalize people who make the responsible choice to pull over or avoid driving altogether.
Justice Feldman’s opinion in Love identified specific factors that lower courts should weigh. No single factor controls the outcome. Instead, the court examines the full picture of circumstances at the time of the encounter. This framework has been applied and refined in subsequent decisions including State v. Zaragoza, which reinforced that courts should consider whether the defendant was attempting to operate the vehicle or had positioned themselves to avoid driving.
| Case | Citation | Key Holding |
|---|---|---|
| State v. Love | 182 Ariz. 324 (1995) | Adopted totality of circumstances test; rejected rigid bright-line approach |
| State v. Zaragoza | 221 Ariz. 49 (2009) | Reinforced that responsible behavior (not driving) weighs in defendant’s favor |
| State v. Haas | 234 Ariz. 453 (2014) | Clarified that vehicle operability is one factor, not dispositive alone |
The Love test shifted the burden analysis significantly. Rather than asking only whether the defendant could have driven, courts now examine whether the totality of evidence suggests the defendant would have driven or was in the process of driving. This distinction matters enormously in cases where someone pulls into a parking lot to sleep, calls a ride-share from the driver’s seat, or is found in a legally parked vehicle with the engine off.
Factors Arizona Courts Weigh in APC Cases
After State v. Love, Arizona courts evaluate actual physical control through a multi-factor analysis. Each case turns on its specific facts, and the weight assigned to each factor varies depending on the circumstances. Understanding these factors reveals where a defense attorney can build arguments for dismissal or acquittal.
Where the ignition key was located is often the most scrutinized factor. Keys in the ignition suggest readiness to operate the vehicle. Keys on the dashboard, in a pocket, or in the center console present a more ambiguous picture. Keys stored in the trunk, glove compartment, or held by a passenger substantially weaken the prosecution’s position. The further the keys are from the ignition, the harder it becomes to argue present capability to drive.
Whether the engine was running carries significant weight. A running engine combined with a driver-seat occupant creates a strong inference of actual physical control. A cold engine that has not been running, verified by hood temperature or officer observation, points away from control. Some defendants leave the engine running solely for heat or air conditioning without any intent to drive, but officers rarely document that distinction at the scene.
Where the defendant was seated matters because the driver’s seat is the only position from which someone can operate a standard vehicle. A person found in the passenger seat, back seat, or even lying across the front seat with the seat reclined to a sleeping position presents different facts than someone seated upright behind the wheel with hands at ten and two. Courts have found that moving to the passenger seat or rear seat before falling asleep demonstrates an intent not to drive.
Whether the vehicle was in gear or in park indicates readiness for movement. A transmission in drive or reverse suggests the vehicle was about to move or had recently been in motion. Park or neutral, particularly combined with the parking brake engaged, suggests the vehicle was stationary by design. Officers typically document the gear position in their report, and this detail can make or break a prosecution.
Whether headlights or other operational indicators were active suggests recent or imminent use of the vehicle. Headlights on, radio playing, and windshield wipers running all point toward a vehicle in active use. A dark, silent vehicle with no operational indicators supports the argument that the person intended to remain stationary.
Where the vehicle was located at the time of the encounter is critical. A vehicle stopped in a travel lane or pulled partially onto a roadway shoulder suggests the driver was operating the car and stopped mid-drive. A vehicle legally parked in a private parking lot, apartment complex, or residential driveway presents a fundamentally different scenario. Courts have noted that someone who drives a vehicle into a private lot and parks before the encounter has arguably completed any driving and is no longer in actual physical control.
Whether the vehicle was operable sets a threshold question. If the vehicle had a flat tire, mechanical failure, or was otherwise incapable of being driven, some courts have found that actual physical control cannot exist. However, this factor alone is not dispositive under Love, and courts may still find control if the mechanical issue was minor or temporary.

Defense Strategies for Actual Physical Control Charges
Because actual physical control cases depend on circumstantial evidence rather than observed driving, they present defense opportunities that standard driving DUI cases do not. An experienced DUI lawyer builds the defense around the Love factors and the specific facts documented in the police report, body camera footage, and witness statements.
Challenge the Totality of Circumstances
Map every Love factor to the facts of your case. If the keys were not in the ignition, the engine was off, the vehicle was legally parked, and you were not in the driver’s seat, the combined weight of these factors can defeat the charge. Even two or three favorable factors may create reasonable doubt about present capability to drive.
Establish the Responsible Choice Defense
State v. Love specifically recognized that Arizona’s DUI law should not punish people who chose not to drive. If you pulled over to sleep, called for a ride, or moved to the passenger seat to wait for a sober driver, these actions demonstrate you were avoiding driving rather than preparing to drive. Document witness testimony, ride-share app records, or phone call logs that corroborate this narrative.
Scrutinize the Officer’s Initial Contact
Officers need reasonable suspicion to conduct an investigatory stop or detention. If you were legally parked in a private lot and the officer approached without a legitimate basis, any evidence gathered after that contact may be suppressible under the Fourth Amendment. Private parking lots at bars, restaurants, and apartment complexes are common contact points where officers may lack reasonable suspicion of a traffic violation.
Contest Chemical Test Results
Even in actual physical control cases, the prosecution must prove impairment or a BAC at or above 0.08 at the time of driving or control. Challenge the blood draw procedure, chain of custody, lab calibration records, or the time gap between the encounter and the chemical test. Request independent retesting of a preserved blood sample through a private laboratory to verify the state lab’s reported BAC.
The designated driver scenario presents a unique defense posture. If you were waiting in the vehicle to drive a sober friend home and had not been driving, the prosecution must prove you were in actual physical control while impaired. The fact that you were the designated driver does not automatically establish control if the vehicle was parked and you were waiting for passengers. However, sitting in the driver’s seat with keys in the ignition while intoxicated can undermine this defense. The strongest position is to wait outside the vehicle or in the passenger seat until passengers arrive.
The sleeping-in-your-car scenario is where State v. Love provides the most protection. Arizona courts have increasingly recognized that arresting someone for choosing to sleep rather than drive contradicts the statute’s purpose of preventing impaired driving. The defense is strongest when the vehicle is legally parked in a lot or driveway, the engine is off and cold, keys are not in the ignition, and the defendant is in a reclined or rear-seat sleeping position. Courts in Tempe, Mesa, and Scottsdale regularly adjudicate these cases, and the outcome depends heavily on how thoroughly the defense attorney documents and argues the Love factors.

Frequently Asked Questions
Arizona courts can charge you with actual physical control DUI under ARS 28-1381 for sleeping in your vehicle while impaired, even if the engine is off and you never drove. The totality of circumstances test from State v. Love evaluates factors like where you were seated, where the keys were, whether the engine was warm, and where the vehicle was parked. Sleeping in the back seat with keys in the trunk presents a stronger defense than sleeping behind the wheel with keys in the ignition.
Arizona courts apply a totality of the circumstances test established in State v. Love, 182 Ariz. 324 (1995). The key factors include whether the engine was running, where the ignition key was located, where the defendant was seated in the vehicle, whether the vehicle was in gear or in park, whether headlights were on, whether the vehicle was operable, and whether the vehicle was on a public roadway or in a private parking area. No single factor is dispositive and courts weigh all circumstances together.
No. ARS 28-1381 prohibits both driving and being in actual physical control of a vehicle while impaired. Actual physical control does not require any driving or vehicle movement. The prosecution must prove only that the defendant had the ability and present capability to operate the vehicle while impaired. This means someone sitting in a parked car with access to the keys can face the same DUI penalties as someone stopped while actively driving.
Penalties mirror those for a standard driving DUI under ARS 28-1381 because the statute treats both offenses identically. A first-offense conviction carries a minimum of 10 consecutive days in jail with 9 days suspendable upon completion of alcohol screening and treatment, fines and surcharges exceeding $2,500, mandatory ignition interlock device installation, license suspension, alcohol education classes, and community service. Extreme BAC levels or prior offenses escalate the mandatory minimums significantly.
Defense strategies focus on the totality of circumstances factors from State v. Love to argue the defendant lacked present capability to operate the vehicle. Key arguments include that the defendant was in the passenger or back seat, keys were inaccessible such as in the trunk or glove box, the engine was cold and off, the vehicle was legally parked in a private lot, and the defendant was attempting to act responsibly by not driving. Additional defenses may challenge the traffic stop legality, field sobriety test administration, or chemical test accuracy.
