A passenger usually cannot be convicted of DUI in Colorado merely because the driver was impaired. A DUI charge generally requires evidence that the accused person drove or was in actual physical control of a vehicle while impaired by alcohol, drugs, or both. A passenger may still face drug possession, open-container, obstruction, or other allegations when the evidence connects that person to unlawful conduct.
If police accuse you of an offense after a traffic stop, the details matter. Officers may focus on where an item was found, who controlled the area, what each person said, whether the vehicle was moving, where the keys were located, and whether the search complied with constitutional requirements.
The Law Firm of Mark S. Hanchey and Ben Peterson represent people facing DUI, drug possession, and related criminal allegations in Colorado Springs, Colorado, and nearby areas.
Can a Passenger Be Charged With DUI in Colorado? 
In most cases, a person who remained a passenger cannot be convicted of DUI because Colorado DUI law applies to a person who drove or exercised actual physical control over a vehicle while impaired.
The main issue is not whether the passenger consumed alcohol or drugs. The prosecution must connect that person to driving or control of the vehicle.
A passenger may become a DUI suspect when the facts suggest that the person drove before officers arrived. Examples may include:
- The vehicle crashed, and every occupant denies being the driver.
- Occupants switched seats before police arrived.
- A person was found alone in or near a running vehicle.
- A witness identified the passenger as the driver.
- Video, text messages, fingerprints, injuries, or seat-position evidence point to the passenger.
- The passenger admitted driving earlier.
- The driver left the scene before officers arrived.
A person sitting in the passenger seat when police approach is not automatically protected from investigation. Officers may consider the total circumstances, including the location of the keys, whether the engine was running, seat positions, airbag deployment, statements from occupants, witness accounts, and nearby video.
When Actual Physical Control May Become an Issue
Colorado impaired-driving cases do not always require an officer to see the vehicle moving. Prosecutors may use circumstantial evidence to argue that a person had actual physical control of the vehicle.
An impaired person found sleeping in a parked vehicle may face investigation depending on facts such as:
- Where the person was seated
- Whether the keys were accessible
- Whether the engine was running
- Whether the vehicle was operable
- Where the vehicle was located
- Whether the person admitted driving
- Whether other evidence suggested recent driving
A true passenger who did not drive and could not control the vehicle generally has a stronger defense against a DUI allegation. Statements made at the scene can still shape the investigation. You should not guess, accept blame for another person, or make an inaccurate statement to protect a friend.

A Passenger Is Not Automatically Responsible for the Driver’s DUI
Your presence in a vehicle does not make you legally responsible for another person’s impaired driving. Police still need evidence connecting you to a specific offense.
A passenger may face a separate allegation if police claim that the passenger:
- Interfered with the investigation
- Gave false identifying information
- Helped hide evidence
- Possessed drugs or unlawful items
- Violated an open-container law
- Allowed an unlicensed person to drive in circumstances covered by another law
Callout: Being near illegal drugs is not the same as knowingly possessing them. The prosecution must connect you to the substance with evidence.
Can a Passenger Be Charged With Drug Possession?
Yes. A passenger may be charged with unlawful drug possession when police claim that the passenger knowingly possessed a controlled substance. Colorado Revised Statutes section 18-18-403.5 addresses unlawful possession of controlled substances.
Possession does not always require drugs to be found in your hand, pocket, or bag. Prosecutors may rely on actual possession, constructive possession, or joint possession.
- Actual possession generally means the substance was physically on your person.
- Constructive possession may be alleged when the substance was not on your person, but the prosecution claims that you knew about it and had the ability and intent to exercise control over it.
- Joint possession may be alleged when more than one person exercised control over the same substance.
Cases involving several people in one vehicle are highly fact-specific. Proximity alone may not prove guilt, but the location of the substance and the surrounding evidence can affect the case.
Where the Drugs Were Found Matters
Police and prosecutors may examine whether suspected drugs were found:
- In your clothing, purse, backpack, or luggage
- Under your seat
- Inside a door pocket next to you
- In a center console accessible to several occupants
- In the glove compartment
- In the trunk
- Inside a container marked with a name
- Beside identification, mail, medication, or personal property
- In plain view
- In an area controlled mainly by the driver
A substance found in your pocket presents a different case from a substance found in a closed console inside another person’s vehicle. When several occupants could access the same area, the prosecution may have difficulty proving who knew about the item and who controlled it.

With You Every Step of the Journey
Evidence Police May Use Against a Passenger
Officers may consider more than the physical location of suspected drugs. Evidence may include:
- Statements from the driver or other passengers
- Admissions made during questioning
- Fingerprints or DNA on packaging
- Text messages discussing a purchase, sale, or delivery
- Cash, scales, baggies, or alleged drug paraphernalia
- Attempts to hide, discard, or move an item
- Body-camera or dashboard-camera footage
- Odor observations
- Prescription bottles bearing another person’s name
- Ownership of the bag or container holding the substance
- Photos, social media messages, or location data
- Laboratory results identifying the substance
You should not assume that everyone in the vehicle will be charged. You also should not assume that only the driver or vehicle owner can be charged. Officers may cite, arrest, or release occupants depending on the evidence and the offense under investigation.
Can Everyone in the Vehicle Be Arrested?
Police may detain several occupants while they investigate who controlled a substance or unlawful item. An arrest does not prove guilt. It means officers believed probable cause existed at that stage.
Colorado law also limits custodial arrest in some narrow drug-possession situations. When the sole suspected offense is certain level 1 drug-misdemeanor possession and officers rely on a colorimetric field test, the law may require a summons rather than an arrest. Other allegations, warrants, safety concerns, or additional evidence may change that result.
The prosecution must still prove each defendant’s guilt beyond a reasonable doubt. In a shared vehicle, the defense may challenge whether the state can connect a specific passenger to the drugs rather than merely show that the person was nearby.
A defense lawyer may examine:
- Whether another occupant claimed ownership
- Whether you had access to the location
- Whether the substance was visible
- Whether officers gave inconsistent accounts
- Whether statements were voluntary and reliable
- Whether fingerprints, DNA, or digital evidence support possession
- Whether the state can prove knowledge and control
Bridgette Carabajal I've had the pleasure of working with Mr. Hanchey on two occasions, and each interaction has been nothing short of exceptional. His professional demeanor, coupled with the outstanding support from his staff significantly alleviated any anxieties I had. I am thoroughly satisfied with the outcomes achieved. Should the need for legal representation arise in the future, Mr. Hanchey will undoubtedly be my first choice. Lucas Garcia Mark Hanchey has been excellent. I spoke with him last minute before my court date. He still showed up to court with me and was very caring and helped me before I had even officially hired him. I felt like he cared about me and my case. He knows his craft very well and you can tell that the judge and other attorneys respect him when he is in court. He is also very kind. I recommend him to anyone. An excellent attorney. Renee Braucht I had an amazing experience with the Hanchey Law Firm! Mr. Hanchey got me the absolute best result I could have imagined for my case.

Marijuana, Open Containers, and Passenger Conduct
Colorado permits limited adult possession of marijuana, but that does not make every form of possession or use inside a vehicle lawful. Passengers may face allegations involving an open marijuana container, unlawful use in a vehicle, underage possession, unlawful quantities, or another controlled substance.
Colorado Revised Statutes section 42-4-1305 addresses open alcoholic beverage containers in the passenger area of a motor vehicle on a public highway. Colorado Revised Statutes section 42-4-1305.5 addresses open marijuana containers and marijuana use in a motor vehicle.
The exact allegation depends on the substance, quantity, age of the person, type of container, location, and surrounding conduct. You should keep lawfully prescribed medication in the proper container and should never use another person’s prescription.
What Happens During a Vehicle Search?
A vehicle search may arise from consent, probable cause, a warrant, an arrest-related search, an inventory search, or another recognized legal basis. The legality and scope of the search may become central defense issues.
A passenger may have privacy rights in personal property, including a purse, backpack, or closed container, even when the passenger does not own the vehicle. The extent of those rights depends on the facts.
A defense attorney may ask:
- Why did the officer stop the vehicle?
- How long were the occupants detained?
- Did anyone consent to a search?
- Who gave consent?
- Did the consent cover your personal bag or container?
- Did officers have probable cause?
- Was a drug-detection dog used lawfully?
- Did officers exceed the permitted scope of the search?
- Did officers search before or after an arrest?
- Were your statements obtained after an unlawful detention?
- Was body-camera footage preserved?
Evidence obtained through an unconstitutional search may be subject to suppression. Suppression can weaken the prosecution’s case and may prevent certain evidence from being used in court.
What Should a Passenger Do During a Traffic Stop?
You should remain calm, avoid sudden movements, and follow lawful safety instructions. You should not physically interfere with officers or attempt to hide, move, or discard an item.
You may identify yourself when legally required, but you should be cautious about answering detailed questions concerning ownership, drug use, travel, or another occupant’s conduct. You may state that you wish to remain silent and want to speak with an attorney.
You should not agree with an officer’s assumptions merely to end the conversation. A statement such as, “I knew it was there, but it was not mine,” may be used to show knowledge even though you intended to deny ownership.
You should also avoid:
- Taking responsibility for an item that is not yours
- Guessing about who owned a substance
- Giving false information
- Arguing physically with an officer
- Consenting to a search without understanding the request
- Discussing the incident on social media
- Deleting messages, photos, or location data
Potential Defenses to Passenger Drug Charges
The available defenses depend on the evidence. Common issues may include:
Lack of Knowledge
You did not know that the substance was present. This issue may arise when drugs were hidden in another person’s bag, vehicle compartment, or property.
Lack of Control
You did not own, access, or control the place where the substance was found.
Mere Proximity
You were close to the drugs, but the state lacks evidence connecting you to them.
Another Person’s Possession
The substance belonged to the driver or another occupant, and independent evidence supports that conclusion.
Unlawful Stop or Search
Officers lacked a lawful basis for the stop, extended the detention without adequate justification, or searched beyond the permitted scope.
Unreliable Testing
The substance was misidentified, contaminated, improperly handled, or not confirmed through reliable testing.
Insufficient Chain of Custody
The prosecution cannot adequately establish how the evidence was collected, stored, transferred, and tested.
Unreliable Statements
An occupant may have blamed you to avoid personal responsibility, obtain favorable treatment, or shift attention from another person.

A Common Passenger Scenario
Consider a Colorado Springs traffic stop involving a driver and two passengers. Officers search the vehicle and find suspected cocaine inside a closed center console. The driver owns the car. One passenger sits next to the console, while the other sits in the back seat.
Physical proximity may lead officers to ask questions, but proximity does not establish who knew about the substance or who controlled it. Relevant facts may include:
- Who owned the vehicle
- Who used the vehicle most often
- Whose fingerprints or DNA were on the packaging
- Whether anyone made an admission
- Whether the console was locked
- Whether personal property linked one person to the drugs
- Whether messages discussed the substance
- Whether the search was lawful
- Whether laboratory testing confirmed the substance
A careful defense investigation separates assumptions from evidence. That distinction can be decisive in a vehicle with several occupants.
Speak With a Colorado Springs Criminal Defense Attorney
