Understanding Colorado's Assault Charges: Misdemeanor vs. Felony

Understanding Colorado’s Assault Charges: Misdemeanor vs. Felony

Quick Answer: Is Assault a Misdemeanor or Felony in Colorado?

Assault can be either a misdemeanor or felony in Colorado. Third-degree assault is generally a class 1 misdemeanor. Second-degree assault is generally a class 4 felony, although certain circumstances change its classification. First-degree assault is generally a class 3 felony. The degree of assault depends on more than simply how badly someone was injured. Colorado law considers the defendant's mental state, the type and severity of injury, whether a deadly weapon was involved, how the injury occurred, who the alleged victim was, and other circumstances. First- and second-degree assault can also trigger Colorado's mandatory crime-of-violence sentencing provisions in specified circumstances.

Key Takeaways for Colorado Assault Charges

• Colorado divides assault into first, second, and third degrees.
• Third-degree assault is generally a class 1 misdemeanor.
• Second-degree assault is generally a class 4 felony, but certain forms have different classifications.
• First-degree assault is generally a class 3 felony.
• "Bodily injury" and "serious bodily injury" have specific—and very different—legal definitions.
• First-degree assault is subject to Colorado's crime-of-violence sentencing statute, while crime-of-violence treatment of second-degree assault depends on the particular statutory subsection and circumstances.
• Colorado recognizes a heat-of-passion mitigator for qualifying first- and second-degree assault cases.
• An assault committed as an act of domestic violence can result in additional consequences involving protection orders, treatment, firearm restrictions, and other requirements.

How Does Colorado Classify Assault Charges?

Colorado does not determine the degree of assault based solely on the seriousness of the injury. The applicable charge can depend on several factors, including:

• Whether the defendant acted intentionally, knowingly, recklessly, or with criminal negligence;
• Whether the alleged victim suffered bodily injury or serious bodily injury;
• Whether a deadly weapon was used;
• Whether strangulation or suffocation was alleged;
• Whether the alleged victim was a peace officer, firefighter, emergency medical provider, or another person given special protection under the statute;
• Whether the injury occurred during certain other felonies; and
• Whether other aggravating or mitigating circumstances apply.

As a general overview:

Assault Degree	General Classification	Basic Sentencing Consideration
Third degree	Class 1 misdemeanor	Up to 364 days in jail and/or up to a $1,000 fine
Second degree	Generally class 4 felony	Felony sentencing varies depending on the particular subsection and whether enhanced sentencing applies
First degree	Generally class 3 felony	Subject to Colorado's crime-of-violence sentencing provisions
Second degree — qualifying heat of passion	Class 6 felony	Reduced classification when statutory requirements are established
First degree — qualifying heat of passion	Class 5 felony	Reduced classification when statutory requirements are established

This is only a general framework. Colorado's assault statutes contain multiple ways of committing first- and second-degree assault, and the precise subsection matters substantially for sentencing.

Third-Degree Assault in Colorado

Third-degree assault under C.R.S. § 18-3-204 is generally a class 1 misdemeanor. One common way of committing third-degree assault is knowingly or recklessly causing bodily injury to another person. But that is not the only way the statute can apply. A person can also commit third-degree assault by causing bodily injury with a deadly weapon through criminal negligence. The statute additionally covers certain conduct involving bodily fluids or hazardous materials directed at specified emergency or public-safety personnel when the required intent exists. For offenses subject to Colorado's current misdemeanor sentencing structure, a class 1 misdemeanor can carry:

• Up to 364 days in jail; and
• A fine of up to $1,000.

How Much Injury Is Required?

Colorado's definition of "bodily injury" is broad. It includes physical pain, illness, or any impairment of physical or mental condition. That means an assault allegation does not necessarily require a broken bone, hospitalization, or visible injury. Reported physical pain can potentially satisfy the bodily-injury element. This is why conduct such as a punch, shove, kick, or other physical contact can sometimes support a third-degree assault charge even when the alleged injury appears relatively minor. Whether the prosecution can actually prove bodily injury is a separate question that depends on the evidence.

Second-Degree Assault in Colorado

Second-degree assault under C.R.S. § 18-3-203 covers several different forms of conduct. It is generally a class 4 felony, although particular circumstances can change the classification or sentencing requirements. Examples covered by the statute include, among other conduct:

• Intentionally causing bodily injury with a deadly weapon;
• Intentionally causing serious bodily injury;
• Recklessly causing serious bodily injury by means of a deadly weapon;
• Intentionally administering a drug or substance to cause stupor, unconsciousness, or another specified impairment;
• Certain assaults against peace officers, firefighters, emergency medical providers, and specified public employees; and
• Intentionally causing bodily injury by strangulation or suffocation as described by the statute.

The precise subsection charged matters because second-degree assault does not have one universal sentencing rule.

Second-Degree Assault by Strangulation

Colorado's second-degree assault statute includes causing bodily injury by applying sufficient pressure to another person's neck or by blocking the person's nose or mouth to impede or restrict breathing or blood circulation, when done with the required intent. Colorado also changed the sentencing rules for certain strangulation cases in 2026. Effective September 1, 2026, Colorado law requires enhanced crime-of-violence sentencing for a qualifying subsequent conviction for second-degree assault by strangulation when the statutory prior-conviction requirements are satisfied. Because this provision is new, older online descriptions of Colorado strangulation sentencing may not reflect current law.

Heat of Passion and Second-Degree Assault

Colorado recognizes a heat-of-passion mitigator that can significantly change the classification of second-degree assault. When the act causing the injury occurs upon a sudden heat of passion caused by a serious and highly provoking act of the intended victim, affects the defendant sufficiently to excite an irresistible passion in a reasonable person, and occurs without enough time for reason to return, second-degree assault can be classified as a class 6 felony. This is not simply a defense based on being angry. The statute imposes specific requirements concerning the nature of the provocation, the defendant's response, and the absence of a sufficient cooling-off period. Colorado law also provides that heat of passion cannot be based solely on discovery, knowledge, or potential disclosure of another person's actual or perceived gender, gender identity, gender expression, or sexual orientation.

First-Degree Assault in Colorado

First-degree assault under C.R.S. § 18-3-202 is generally a class 3 felony. The statute includes several different forms of conduct. Examples include intentionally causing serious bodily injury with a deadly weapon and, under specified circumstances, causing serious bodily injury while acting with extreme indifference to the value of human life. A conviction for first-degree assault under the statute is subject to Colorado's crime-of-violence sentencing provisions. That makes first-degree assault substantially more serious than an ordinary felony carrying only the standard presumptive sentencing range. The actual sentence depends on the subsection of conviction, applicable sentencing statutes, criminal history, aggravating or mitigating circumstances, and other factors. For that reason, it is safer and more accurate to evaluate sentencing based on the precise charge rather than assuming every first-degree assault case carries one fixed prison range.

Heat of Passion and First-Degree Assault

First-degree assault also has a heat-of-passion provision. When the statutory requirements are established, first-degree assault is reduced from a class 3 felony to a class 5 felony. As with second-degree assault, the standard is demanding. The injury must result from a sudden heat of passion caused by a serious and highly provoking act of the intended victim, and there cannot have been enough time between the provocation and injury for reason to return. The Colorado statute also expressly limits what can constitute legally sufficient provocation.

Bodily Injury vs. Serious Bodily Injury

The distinction between bodily injury and serious bodily injury can be critical in a Colorado assault case.

Bodily Injury

Colorado defines bodily injury as:

• Physical pain;
• Illness; or
• Any impairment of physical or mental condition.

This is a relatively broad definition. An alleged victim does not necessarily need a visible wound or significant medical treatment for prosecutors to allege bodily injury.

Serious Bodily Injury

Serious bodily injury is substantially more serious. Colorado law includes bodily injury that, either at the time of the injury or later:

• Involves a substantial risk of death;
• Creates a substantial risk of serious permanent disfigurement;
• Creates a substantial risk of protracted loss or impairment of the function of a body part or organ;
• Involves a break or fracture;
• Involves a penetrating knife wound;
• Involves a penetrating gunshot wound; or
• Involves second- or third-degree burns.

Colorado added penetrating knife and gunshot wounds to this definition effective July 1, 2023. The distinction can significantly affect the charge. But it is important not to oversimplify that relationship: the injury level alone does not determine the degree of assault. The defendant's mental state, use of a weapon, manner in which the injury occurred, and precise statutory subsection also matter.

What Is Harassment in Colorado?

Harassment is a separate offense governed by C.R.S. § 18-9-111. Unlike assault, harassment does not necessarily require proof that the alleged victim suffered bodily injury. Depending on the subsection, harassment can involve conduct such as:

• Striking, shoving, kicking, or otherwise touching another person;
• Subjecting another person to physical contact;
• Following someone in or around a public place;
• Certain obscene gestures;
• Certain communications; or
• Other conduct covered by the statute,

when accompanied by the intent required under Colorado law. Because assault and harassment contain different elements, the distinction can become important in both charging decisions and plea negotiations. A harassment disposition may sometimes be negotiated as an alternative to an assault charge, but whether harassment is a legally available lesser offense depends on the particular charges, statutory elements, facts, and procedural posture. For that reason, I would not characterize harassment categorically as either always or never a lesser-included offense of every form of assault.

When Does Assault Become a Domestic Violence Case?

Domestic violence is generally not a separate criminal offense in Colorado. Instead, Colorado law applies the domestic-violence designation when an underlying crime is committed as an act of domestic violence as defined by statute. An intimate relationship between the people involved is important, but the existence of that relationship alone does not automatically transform every alleged offense into domestic violence. Colorado's definition generally concerns an act or threatened act of violence against a person with whom the defendant is or has been involved in an intimate relationship. It also encompasses certain other crimes committed as a method of coercion, control, punishment, intimidation, or revenge directed against a person with whom the defendant has or had an intimate relationship.

Mandatory Arrest

Colorado has a mandatory-arrest provision for domestic-violence cases. When an officer determines there is probable cause to believe a crime or offense involving domestic violence has been committed, Colorado law generally directs the officer to arrest the suspected offender without undue delay. That does not mean every domestic-violence accusation automatically requires an arrest. Probable cause is still required.

Protection Orders

A criminal case may also result in a mandatory criminal protection order. The exact terms matter. A defendant should follow the written order rather than assuming contact is permitted because the alleged victim initiates or agrees to it.

Firearms

Domestic-violence cases can also create firearm consequences under Colorado and federal law. Those consequences depend on factors including the protection order, the underlying conduct, and whether the case results in a qualifying conviction. Because firearm restrictions are governed by multiple state and federal provisions, they should be evaluated based on the specific case rather than described as an automatic consequence of every domestic-violence allegation.

Domestic Violence Treatment

A conviction for an offense involving domestic violence can result in a domestic-violence evaluation and court-ordered treatment as required under Colorado law. Colorado also places restrictions on plea agreements that remove the domestic-violence designation from a case when the prosecution believes the underlying factual basis includes domestic violence.

What Are Common Defenses to Assault Charges in Colorado?

The appropriate defense depends on the facts and the particular assault subsection charged. Potential issues can include:

Self-Defense

Colorado permits a person to use physical force in specified circumstances when the person reasonably believes another person is using or is about to use unlawful physical force. The amount and type of force that may legally be used depend on the circumstances.

Defense of Another Person

Colorado law can also justify qualifying uses of force to protect another person.

Defense of a Dwelling

Colorado provides separate rules concerning the use of physical force against an unlawful intruder in a dwelling. Those rules have specific statutory requirements and should not be treated as a blanket right to use force against anyone who enters property without permission.

Lack of the Required Mental State

Different forms of assault require different mental states, including intentional, knowing, reckless, or criminally negligent conduct. The prosecution must prove the mental state required by the particular subsection charged.

Mistaken Identity

Video, electronic evidence, witness testimony, or other evidence may establish that the defendant was not the person who caused the injury.

No Bodily Injury

For charges requiring bodily injury, the defense may challenge whether the prosecution can establish physical pain, illness, or impairment.

Disputed Serious Bodily Injury

When the charge depends on serious bodily injury, medical records, expert testimony, photographs, and other evidence may become important in determining whether the statutory definition is actually satisfied.

Can Assault Charges Be Reduced or Dismissed in Colorado?

Yes, assault charges can sometimes be reduced or dismissed, but neither outcome is automatic. Potential issues affecting the resolution can include:

• Self-defense;
• Insufficient evidence;
• Witness credibility;
• Conflicting accounts;
• Video or electronic evidence;
• Whether the prosecution can prove bodily or serious bodily injury;
• Whether a deadly weapon was actually involved;
• Whether the required mental state can be proven;
• Suppression of evidence; and
• Other factual or legal problems.

The alleged victim does not personally control whether a criminal charge is dismissed. The prosecution makes charging decisions and may seek dismissal of a filed charge, while the court has the formal role in dismissing charges and can also dismiss in circumstances authorized by law. A victim's wishes can be relevant to the prosecutor's evaluation of a case, but a request to "drop the charges" does not automatically terminate the prosecution.

FAQ: Colorado Assault Charges

Is Third-Degree Assault a Felony in Colorado?

Generally, no. Third-degree assault under C.R.S. § 18-3-204 is generally a class 1 misdemeanor. A class 1 misdemeanor under Colorado's current sentencing structure can carry up to 364 days in jail and/or a fine of up to $1,000. Different statutes can apply when the alleged victim belongs to a specially protected category, so the precise charge should always be reviewed.

How Much Jail or Prison Time Can You Face for Assault in Colorado?

It depends on the degree of assault, the subsection charged, criminal history, whether crime-of-violence sentencing applies, and other circumstances. Third-degree assault is generally a class 1 misdemeanor carrying up to 364 days in jail. First- and second-degree assault are felonies in their ordinary forms, and certain convictions are subject to enhanced or mandatory sentencing provisions. Because the sentencing rules differ significantly among assault subsections, the precise charge matters more than the word "assault" by itself.

Can the Victim Drop Assault Charges in Colorado?

Not by themselves. The alleged victim can tell prosecutors what outcome they want, and their position may be considered. But criminal charges are prosecuted by the government. The prosecutor generally decides whether to continue pursuing a charge or seek dismissal, subject to the court's role in formally dismissing a filed case.

What Is the Difference Between Assault and Harassment?

Assault generally involves causing bodily injury or other specifically prohibited conduct under Colorado's assault statutes. Harassment is a separate offense and can apply to certain unwanted physical contact or other conduct performed with the intent to harass, annoy, or alarm. Harassment does not always require bodily injury.

Is Assault a Crime of Violence in Colorado?

Some assault convictions are subject to Colorado's crime-of-violence sentencing statute. First-degree assault is expressly subject to C.R.S. § 18-1.3-406. Certain forms of second-degree assault are also subject to crime-of-violence or other enhanced sentencing provisions. The answer therefore depends on the particular statutory subsection and circumstances rather than simply whether the charge is labeled "assault."

Can I Claim Self-Defense in a Colorado Assault Case?

Potentially. Colorado's self-defense statute permits qualifying uses of physical force when a person reasonably believes another person is using or is about to use unlawful physical force. Whether self-defense applies depends on the circumstances, including what occurred, what the defendant reasonably believed, who initiated the confrontation, and the nature of the force used.

Will an Assault Conviction Affect My Gun Rights?

It can. Felony convictions and qualifying misdemeanor domestic-violence convictions can create firearm restrictions under state or federal law. Certain protection orders can also affect firearm possession. The exact consequence depends on the conviction, underlying conduct, court orders, and applicable state and federal law.
