What Is Considered Actual Physical Control In A Colorado DUI Case?
Many people think a Boulder DUI charge only happens if an officer sees someone driving. This can be a shock when police arrest someone in a parked car. In Colorado, prosecutors can file DUI, DWAI, or DUID charges if they believe a person had actual physical control of a vehicle, even if it was not moving. For example, someone asleep in the driver’s seat, sitting in a parked car, or using a car for shelter might still be investigated for impaired driving.
We know these situations can be confusing because the usual idea of “driving” is not always the same as the legal definition in Colorado. At Watkins Law Firm LLC, we look at every detail, including the vehicle, the keys, where the person was, the car’s condition, and the police investigation.
Colorado DUI Law Does Not Require Proof That The Vehicle Moved
Colorado’s main impaired-driving law, C.R.S. § 42-4-1301, makes it illegal to drive under the influence of alcohol, drugs, or both. It also bans driving while ability is impaired or with too much alcohol in your blood. Even though the law says “driving,” Colorado courts have decided that prosecutors do not always have to show the vehicle actually moved.
C.R.S. § 42-1-102(27) defines a “driver” as a person who drives or is in actual physical control of a vehicle. The Colorado Supreme Court relied on that definition in People v. Swain, 959 P.2d 426 (Colo. 1998). The court held that “drive,” for purposes of Colorado’s DUI law, includes being in actual physical control of a vehicle. As a result, the prosecution may try to prove the driving element through circumstantial evidence rather than testimony that someone saw the vehicle in motion.
What Actual Physical Control Means In Colorado
Actual physical control is about whether someone had control over a vehicle. Colorado courts look at all the facts together, not just one detail. The main question is whether the person could control a vehicle that could be driven.
In Swain, the Colorado Supreme Court said courts should look at several things. These include where the vehicle was, where the person was inside the car, if the keys were in the ignition, if the engine was running, and any other sign that the person had control over the vehicle. No single detail proves or disproves actual physical control.
So, just because the engine is off does not mean someone cannot be accused of DUI. But simply being inside a vehicle does not always mean they had actual physical control. We look at all the facts together to see if the prosecution can prove their case beyond a reasonable doubt.
The Driver’s Seat, Keys, And Engine Are Important
Someone found in the driver’s seat is more likely to face an actual-physical-control charge than someone sleeping in the back seat. Where the keys are found is also important. If the keys are in the ignition, in the driver’s hand, or close by, it can help the prosecution argue that the car could be started quickly.
A running engine creates another significant fact. Colorado courts have found actual physical control when an impaired person was behind the steering wheel of a running vehicle because only minimal activity would be needed to put it in motion. In Notarmuzi v. Colorado Department of Revenue, 2025 COA 20, the Colorado Court of Appeals explained that movement or shifting into gear was not required when the person was in the driver’s seat with the engine running.
If the engine is off, the investigation does not stop there. Police and prosecutors may look at where the person was, if they had the keys, what they said, where the car was parked, if the engine was warm, tire tracks, witness stories, or other clues. We check for missing evidence instead of just accepting the police version.
Sleeping In A Parked Car Can Still Lead To A DUI Arrest
Some people sleep in their cars because they think it is safer than driving while impaired. While this is a responsible choice, sleeping in a car can still lead to an arrest if police think the person had actual physical control. Someone sleeping in the driver’s seat with the keys in the ignition faces a different situation than someone in the back seat with the keys put away.
Where the vehicle is parked can also affect the case. If the car is stopped in a traffic lane, parked the wrong way, against a curb, or in a spot that looks like it was just driven, this can help the prosecution. A car parked legally on private property may be different, but being on private property does not always stop a DUI charge in Colorado.
We check if anyone saw the person drive, if someone else could have been the driver, when alcohol or drugs were used, and if the car could run. These details can raise reasonable doubt about actual physical control or whether the person was impaired at the time.
The Vehicle Must Be Reasonably Capable Of Being Operated
Colorado appellate decisions have stated that actual physical control requires a vehicle that is reasonably capable of being rendered operable. This issue may become important when a vehicle is disabled, damaged, out of fuel, missing essential parts, or otherwise unable to move.
A minor mechanical problem may not be enough to defeat the allegation if the vehicle could be made operable with little effort. By contrast, a vehicle with major damage or a condition that prevents operation may support a defense. We may review photographs, towing records, repair bills, mechanic testimony, body-camera footage, and officer observations to determine whether the vehicle was actually capable of being driven.
The prosecution must establish more than the fact that an impaired person was near a vehicle. It must prove actual physical control of an operable or reasonably operable vehicle, along with the remaining elements of DUI, DWAI, or DUID.
Statements To The Police Can Shape The Case
Statements often become critical in parked-car DUI cases. An officer may ask who drove the vehicle, when it arrived, where the keys came from, why the person was inside, and when alcohol or drugs were consumed. Answers given during a stressful roadside encounter may later be treated as admissions.
A person may also make inconsistent statements because of confusion, fear, fatigue, a medical condition, or misunderstanding. Police may record those statements through body cameras, patrol-car cameras, dispatch recordings, or written reports. We compare the recordings with the officer’s report and challenge inaccurate, incomplete, or misleading descriptions.
The absence of direct driving evidence does not guarantee dismissal, but it can create important defense issues. We evaluate whether the prosecution can establish who controlled the vehicle, when any driving allegedly occurred, and whether the accused person was impaired at that time.
Actual Physical Control Can Trigger Criminal And License Consequences
A finding of actual physical control can support a DUI or DWAI prosecution under C.R.S. § 42-4-1301. The resulting consequences may include jail, probation, fines, public service, alcohol or drug evaluation, treatment requirements, and driver’s license penalties under Colorado law. Sentencing provisions for DUI and DWAI appear in C.R.S. § 42-4-1307.
Actual physical control may also affect Colorado’s express consent process under C.R.S. § 42-4-1301.1. When an officer has probable cause to believe a person drove while impaired, the officer may request a chemical test. A refusal can create separate driver’s license consequences and may be introduced as evidence in the criminal case, subject to applicable law.
A parked-car case should therefore be taken as seriously as any other DUI allegation. The absence of vehicle movement does not eliminate the possibility of criminal prosecution, license revocation, increased insurance costs, employment problems, or a permanent criminal record.
How We Challenge Actual Physical Control Allegations
We begin by reconstructing what happened before the police arrived. We identify the vehicle’s location, the client’s position, where the keys were found, whether the engine was running, whether the vehicle worked, and whether another person had driven. We review body-camera footage, surveillance recordings, witness statements, dispatch records, chemical testing, field sobriety testing, and the officer’s basis for making contact.
We also examine whether the officer lawfully detained the client and whether probable cause supported the arrest. In some cases, the main dispute concerns actual physical control. In others, the evidence may raise separate issues involving impairment, chemical testing, rising blood alcohol levels, prescription medication, marijuana, medical conditions, or unlawful police conduct.
The phrase “actual physical control” allows prosecutors to file a DUI charge without proving visible movement. It does not relieve them of their duty to prove every element beyond a reasonable doubt. We use the details of the encounter to test the prosecution’s theory and protect our client’s license, record, and future.
Frequently Asked Questions About Actual Physical Control In Colorado DUI Cases
Can We Be Charged With DUI For Sleeping In A Parked Car In Colorado?
Yes. A person may be arrested and charged with DUI, DWAI, or DUID while sleeping in a parked vehicle if police believe the person was in actual physical control. The court may consider whether the person was in the driver’s seat, whether the keys were in the ignition or within reach, whether the engine was running, where the vehicle was parked, and whether the vehicle was operable. Sleeping in the back seat with the keys stored away may present a more favorable set of facts, but no single fact decides the case. We evaluate the entire situation under the totality-of-the-circumstances standard recognized in People v. Swain.
Does The Engine Have To Be Running For Actual Physical Control?
No. A running engine is strong evidence for the prosecution, but Colorado law does not make it an absolute requirement. Prosecutors may argue that a person exercised actual physical control while sitting behind the wheel with immediate access to the keys, even when the engine was off. We may respond by showing that the person had no intent or practical ability to operate the vehicle, the keys were inaccessible, the person was not in the driver’s seat, or the vehicle could not run. The outcome depends on how all the facts fit together.
Can We Get A DUI On Private Property In Colorado?
A vehicle’s presence on private property does not automatically prevent a DUI charge. Colorado’s actual-physical-control analysis focuses on control of the vehicle, not simply whether the vehicle was on a public roadway. A person found behind the wheel in a private parking lot, apartment complex, driveway, or business lot may still be investigated. The location remains relevant, however. A legally parked vehicle in a private driveway may create different inferences from a vehicle stopped in a travel lane or positioned in a way suggesting it was recently driven.
What Happens If Someone Else Drove The Vehicle?
The identity of the driver can become a central defense issue. Police may assume the person found in the vehicle drove it there, but that assumption is not always correct. A friend, family member, rideshare driver, or other person may have driven before leaving the scene. We look for phone records, messages, witnesses, surveillance footage, receipts, location information, and other evidence supporting the client’s account. Even if another person drove earlier, prosecutors may still allege actual physical control based on what occurred after that person left, so the location of the keys and the client’s position remain important.
Does A Broken-Down Vehicle Count For Actual Physical Control?
It depends on whether the vehicle was reasonably capable of being rendered operable. A vehicle that needs only minimal effort to start may still qualify. A seriously damaged or disabled vehicle may support an argument that actual physical control was not possible. We may use towing reports, repair invoices, photographs, diagnostic records, or mechanic testimony to establish the vehicle’s condition. The prosecution should not be allowed to assume operability when physical evidence shows that the vehicle could not be placed in motion.
Can Refusing A Chemical Test Affect A Parked-Car DUI Case?
Yes. Colorado’s express consent law may apply when an officer has probable cause to believe a person drove, which includes actual physical control under Colorado case law. A refusal may lead to administrative driver’s license consequences and may also be presented as evidence in the criminal case when legally permitted. We examine whether the officer had a proper basis to claim actual physical control, whether the advisement was given correctly, and whether the person’s words or conduct amounted to a refusal. Criminal court proceedings and driver’s license proceedings are separate matters with different procedures and deadlines.
