Obstructing a Peace Officer in Colorado: Conduct, Penalties, and Defenses

Obstructing a peace officer in Colorado is a Class 2 misdemeanor under C.R.S. § 18-8-104, punishable by up to 120 days in county jail and a fine of up to $750. The charge requires a physical act — force, violence, physical interference, or creating an obstacle — that knowingly impedes a peace officer, firefighter, paramedic, rescue specialist, or emergency volunteer doing their job. Words alone, including arguing with or insulting an officer, cannot support a conviction.¹

What Prosecutors Have to Prove

Two elements have to be shown beyond a reasonable doubt. First, you acted “knowingly.” That means you were aware your conduct was practically certain to interfere with the official’s work. You don’t have to have set out to cause the interference; it’s enough that you understood the likely effect of what you were doing.¹

Second, the interference had to happen through physical means. The statute lists force, violence, physical interference, or creating an obstacle. It also spells out, in subsection (1.5), that remaining silent or verbally opposing a government official’s order is not a basis for the charge.¹

The official has to be acting under “color of official authority” at the time, meaning a good-faith judgment made in the course of their regular duties. The statute covers more than police. Firefighters working a blaze, paramedics treating a patient, rescue specialists responding to a disaster, and unpaid volunteers providing emergency care at an accident scene all fall within its protection.¹

Conduct That Leads to a Charge

The clearest cases involve physical resistance during an arrest or investigation. Struggling against an officer trying to handcuff you, planting yourself in front of a patrol car so it can’t leave, shoving a paramedic trying to reach an injured person, or placing objects in a roadway to block emergency vehicles all fit the statute. The force doesn’t have to be dramatic. Creating an obstacle is enough.

Interference with equipment counts too. Grabbing an officer’s radio during a call, tampering with fire suppression gear, or disabling emergency lighting is the kind of physical interference the statute targets, and these situations tend to escalate fast because responders treat equipment interference as a direct threat to their safety.

Drones get specific treatment. Flying an unmanned aircraft in a way that obstructs emergency responders falls under the statute. There is one narrow exception: you have explicit permission from the coordinating agency, you stay in communication with them during the flight, and you immediately comply with any instructions they give about your drone.¹

Police K-9s and search-and-rescue dogs are protected under the same statute. Interfering with the animal through force or physical obstruction is treated the same as interfering with its handler.¹

What Does Not Count

The line between obstruction and protected behavior matters a lot in practice, because officers sometimes arrest people for conduct the statute doesn’t actually reach.

Silence and Verbal Opposition

Colorado law is explicit. You cannot be charged with obstruction for staying silent or for verbally opposing an officer’s order.¹ You can tell an officer you disagree, question their authority, or push back in blunt terms. As long as your words don’t amount to threats of violence and you aren’t physically blocking anyone, speech alone can’t be the basis of this charge.

Recording Officers

Under C.R.S. § 16-3-311, you have a right to record any incident involving a peace officer and to keep possession of both the recording and the device.² The limit is physical: filming from a reasonable distance is protected, but stepping into a secured perimeter or blocking an officer’s movement to get a better angle can cross into obstruction.

Voluntary Encounters and ID Requests

If police lawfully detain you based on reasonable suspicion under C.R.S. § 16-3-103, you must give your name and address. Outside that situation — a casual encounter or a stop without reasonable suspicion — you don’t have to identify yourself, and asking whether you’re free to leave or declining to answer questions isn’t obstruction.

Penalties for a Conviction

Obstruction is a Class 2 misdemeanor.¹ For offenses on or after March 1, 2022, the maximum punishment is 120 days in county jail, a fine of up to $750, or both.³ Any jail time is served in a county facility rather than state prison.

Court costs and statutory surcharges stack on top of the base fine and can push the total well past $750. Judges can also impose probation, community service, or other conditions. Aggravating factors like the severity of the interference or significant delay to emergency operations tend to push sentences toward the upper end.

Older conduct carries a heavier range. If the offense occurred before March 1, 2022, the sentencing range was three months to 364 days in jail and a fine of $250 to $1,000.³

Defenses That Actually Work

No Physical Act

This is where weak obstruction cases fall apart. The statute requires force, physical interference, or an obstacle. If all you did was argue, yell, or refuse to answer questions, the charge doesn’t hold. Prosecutors sometimes file obstruction based on verbal confrontations that made an officer’s job harder without any physical component, and those charges are vulnerable to dismissal.

You Didn’t Know Who It Was

If you genuinely didn’t know the person was a peace officer or emergency responder, the “knowingly” element fails. A peace officer has to be in uniform or, if out of uniform, identify themselves by showing credentials.⁴ An unmarked, unidentified officer who never announces themselves creates a strong knowledge defense.

Self-Defense Against Excessive Force

The statute says it’s no defense that the officer was acting illegally, as long as they were operating under color of authority.¹ Colorado courts have carved out an exception, though. If an officer uses unreasonable or excessive force, you may assert self-defense under C.R.S. § 18-1-704, which allows reasonable force to defend against what you reasonably believe to be unlawful physical force. The bar is high: your belief must be reasonable and your response proportional to the threat.

Obstruction vs. Resisting Arrest

These two charges are close cousins and often filed together. Resisting arrest under C.R.S. § 18-8-103 is narrower: it applies only when you use force, threaten violence, or create a substantial risk of bodily injury to prevent an officer from making an arrest.⁴ Obstruction is broader. It covers interference with any official duty, not just arrests, and it doesn’t require a risk of injury.

Both are Class 2 misdemeanors with identical maximum penalties.⁴ If you physically struggled during an arrest, you may face both. If you blocked a firefighter from reaching a building but no arrest was involved, only obstruction applies. Being charged with both for the same incident is common, so sorting out which charge actually fits the facts matters.

Sealing the Record Afterward

A Class 2 misdemeanor obstruction conviction can be sealed, but there’s a waiting period. You have to wait at least two years after either the final disposition of the case or your release from any supervision, whichever is later.⁵ After that, you file a motion with the court and give notice to the district attorney.

If the DA doesn’t object and you’ve picked up no new convictions, the court generally orders the records sealed. If the DA objects, the court holds a hearing and weighs factors like the seriousness of the offense, your criminal history, and the public safety impact of sealing. One firm rule: you can’t seal the record if restitution is still owed, unless the court that ordered it vacates that order.⁵ If a petition is denied, you typically have to wait a year before trying again.
