What Aggravated Unlawful Use of a Weapon Means in Illinois
Illinois defines this offense at 720 ILCS 5/24-1.6. It is a carrying and possession offense. The State does not have to prove you used a firearm, aimed one, threatened anyone, or fired a shot. It has to prove where you were, what you had with you, and one additional fact that the statute treats as an aggravating factor.
That last part is where people often get lost. “Aggravated” sounds like it describes something that happened or the severity of an incident. In this statute it describes a condition: a gun that was loaded, a card you did not have in your wallet, an age, a date on an old court file. The conduct can be identical to a case charged as a misdemeanor. The factor is what moves it.
The difference matters immediately. A base weapons charge in DuPage County is often a Class A misdemeanor. This charge is a felony from the moment it is filed.
Aggravated Does Not Mean Violent
In this statute, the aggravating factor can be a piece of paperwork you did not have on you. A FOID card that lapsed, a concealed carry license still in process, or an age listed on your driver’s license can each supply the element that makes the charge a felony.
Why the Statute Is Now Called Aggravated Unlawful Possession of a Weapon
You will see this offense written two ways. Older paperwork, most attorney websites, and everyday courtroom conversation call it “aggravated unlawful use of a weapon”, or “Agg UUW”. The statute itself now reads “aggravated unlawful possession of a weapon”.
Public Act 103-822 took effect on January 1, 2025 and replaced the word “use” throughout Article 24 of the Criminal Code. The legislature made the change because the old label did not describe what the statute actually reaches. The conduct covered did not change. Neither did the penalties.
If an older record of yours now reads differently than your case file does, that is the relabeling and nothing more. It is not a new charge and not an amended conviction. The same renaming reached the base unlawful possession of a weapon statute on the same day.
The Two Things the State Has to Prove for AUUW
This charge has a structure that is easy to miss, and understanding it is the difference between reading your charging document and guessing at it. The statute requires two separate findings. Both have to be there.
The first is the carrying conduct. Subsection (a)(1) covers carrying a firearm on or about your person, concealed, or in any vehicle. Subsection (a)(2) covers carrying or possessing a firearm on a public street, alley, or other public land inside the limits of a city, village, or incorporated town. One or the other has to apply.
That first half comes with a carve-out written directly into it. The statute does not reach your own land, your abode, your legal dwelling, or your fixed place of business. It also does not reach another person’s dwelling when you are there as an invited guest with that person’s permission.
The second is the aggravating factor. The statute lists a set of them, and at least one has to be present. Without a factor, this charge does not exist. What is left may be a different offense, but it is not this one.
We treat those halves as two separate problems, because that is how the statute is built. A case can fail on either one.
The Carrying Conduct
You carried or possessed a firearm on your person, concealed, or in a vehicle, or you carried or possessed one on a public street or public land within a municipality. Your own home, land, and place of business are excluded, as is a home you were invited into.
The Aggravating Factor
One condition from the statutory list was also present at the time. A single factor is enough, and the factor the State selects determines the offense class and the sentence you are facing.
The Aggravating Factors That Turn Carrying Into a Felony
The statute lists these factors, and the State needs only one of them.
1
Loaded and within reach
The firearm was uncased, loaded, and immediately accessible at the time.
2
Unloaded with ammunition nearby
The firearm was uncased and unloaded, but the ammunition for it was immediately accessible.
3
No valid FOID card
The person carrying the firearm had not been issued a currently valid Firearm Owner’s Identification Card.
4
A prior juvenile adjudication
The person was previously adjudicated a delinquent minor for an act that would have been a felony if committed by an adult.
5
A misdemeanor drug offense at the same time
The person was engaged in a misdemeanor violation of the Cannabis Control Act, the Illinois Controlled Substances Act, or the Methamphetamine Control and Community Protection Act.
6
A recent order of protection
An order of protection was issued against the person within the previous two years.
7
A misdemeanor involving force
The person was committing or attempting a misdemeanor involving the use or threat of violence against another person or their property.
8
Under 21 with a handgun
The person was under 21 years of age and in possession of a handgun, outside the lawful activities the statute exempts.
The Handgun Distinction
Read the loaded and unloaded factors closely and you will find that the statute splits them. There is one version for firearms other than pistols, revolvers, and handguns, and a separate version for handguns.
The handgun versions carry a second requirement. They apply only when the person has not been issued a currently valid license under the Firearm Concealed Carry Act. The long gun versions carry no such requirement.
The practical result is worth understanding before your first court date. A valid concealed carry license removes the handgun factors from the case entirely. It does not do the same for a rifle or a shotgun that was uncased and loaded in your vehicle. Two people carrying different firearms under identical circumstances, both holding the same license, are not in the same position under this statute.
Under 21 With a Handgun
Age is its own factor here. A person under 21 in possession of a handgun supplies the aggravating element on age alone, without regard to whether the firearm was loaded or whether a FOID card existed.
The statute does carve out lawful activity under the Wildlife Code and the exemptions at 720 ILCS 5/24-2, and those exemptions do real work in cases involving hunting, target ranges, and supervised instruction.
DuPage County has a large population in exactly this age range. College of DuPage, the campuses around Wheaton and Naperville, and the commuter corridors along Butterfield and Roosevelt all put young drivers on the road here. Where the person charged is still a minor, the case may proceed through the juvenile system instead, which changes both the procedure and the exposure.
An Order of Protection Within the Past Two Years
If an order of protection was issued against you at any point in the previous two years, that alone can supply the aggravating factor. The order does not have to still be in effect. It does not have to have been contested, and it does not have to have led to any finding against you beyond its own entry.
People are regularly surprised by this one, because an order they consider long resolved is still inside the statutory window. An order of protection or no-contact order entered against you at any point in the last 24 months belongs in the conversation with your attorney on day one, even if you thought that matter closed years ago.
A Misdemeanor Drug or Cannabis Offense at the Same Time
The statute attaches an aggravating factor when the person carrying the firearm was, at that moment, committing a misdemeanor violation of the Cannabis Control Act, the Controlled Substances Act, or the Methamphetamine Control and Community Protection Act.
Legal cannabis in Illinois did not remove this factor from the statute. Possessing cannabis lawfully and transporting it lawfully are two different questions, and the rules about how cannabis must be carried in a vehicle are where this factor tends to arise. A driver who believes the cannabis in the car is entirely legal, and who also has a firearm in the vehicle, can end up facing a felony built on the combination.
One Factor Is Enough
The State needs a single aggravating factor to charge this offense, but it is common for several counts to be filed from one stop. A stack of counts reflects how many factors an officer wrote down, not how strong the case against you is.
Aggravated Unlawful Possession of a Weapon Penalties in Illinois
This offense is a felony in every form. The sentencing structure sits in the last subsection of the statute, and it turns on your record, your status, and which factors were charged.
| Circumstance | Offense class | Sentencing range |
|---|---|---|
| Base offense | Class 4 felony | 1 to 3 years |
| First offense with a firearm, by a person 18 or older, where the loaded and accessible factor and the no FOID card factor are both present | Class 4 felony | A term of imprisonment of 1 to 3 years |
| Second or subsequent offense | Class 2 felony | 3 to 7 years |
| Committed by a person previously convicted of a felony in Illinois or another jurisdiction | Class 2 felony | 3 to 7 years |
| Committed while wearing or in possession of body armor, by a person without a valid FOID card | Class X felony | 6 to 30 years |
The statute also treats the possession of each firearm as a single and separate violation, which is how one search can generate more counts than most people expect.
When Probation Is Available and When It Is Not
A Class 4 felony in Illinois is ordinarily eligible for probation, and on the base version of this offense that option is on the table.
Where the State charges both the loaded and accessible factor and the no FOID card factor together, against an adult on a first offense, the statute directs a term of imprisonment of one to three years. Courts and practitioners read that language as narrowing the probation option considerably compared to a standard Class 4. The conduct in each of those first two scenarios can be identical. What separates them is which factors the State attached when it filed. That is why the charging document deserves close attention before anyone starts talking about outcomes.
Which Factors Are Charged Matters
Two people can be stopped for the same thing on the same afternoon and face different sentencing exposure because of which aggravating factors appear on their charging documents. Reviewing that document line by line is one of the first things we do.
Where a case moves into the higher classes, the exposure changes character entirely, and the ranges attached to each class of Illinois felony become the frame for every decision that follows.
The Exceptions Written Into the Statute
The statute excludes certain ways of carrying a firearm from its reach. These are not requests for leniency. If one applies to you, the conduct the State charged was not an offense under this section.
- The firearm was broken down into a non-functioning state. A weapon that cannot be fired as it sits is outside this statute.
- The firearm was not immediately accessible. Distance and containment both count. A firearm in a locked trunk is in a different position than one in a center console.
- The firearm was unloaded and enclosed in a case, and you hold a valid FOID card. The statute names a firearm carrying box, a shipping box, or another container, and it requires a currently valid Firearm Owner’s Identification Card.
Why a Concealed Carry License Is Not on This List
Anyone comparing this statute to the base weapons law will notice something missing. On the base charge, lawful carry under the Firearm Concealed Carry Act appears as an exception. Here it does not.
Under this statute, the concealed carry license does its work inside the elements themselves. It sits in the handgun versions of the loaded and unloaded factors, where the State has to show the person had not been issued a currently valid license. If you hold one, those factors do not apply to you, and the State never reaches the exception list.
Same card, two different jobs. It is the clearest illustration of why 720 ILCS 5/24-1 and this section have to be read as separate laws rather than as two versions of the same idea.

The Constitutional History of This Statute
Few Illinois criminal statutes have been through what this one has. Parts of it have been struck down, rewritten, and challenged again. If you are facing this charge, or carrying an old conviction under it, that history is worth understanding.
Convictions Under the Older Version May Be Void
In 2013, the Illinois Supreme Court decided People v. Aguilar and held that one combination in this statute, the carrying provision paired with the loaded and accessible factor, was facially unconstitutional under the Second Amendment. In 2015, People v. Burns confirmed that the holding was not limited to a particular offense class, correcting language in the earlier opinion that had suggested otherwise.
A statute found facially unconstitutional is treated as void from the beginning. That is why convictions entered years before those decisions have been vacated afterward, and why a constitutional challenge to a criminal statute can generally be raised at any point rather than being lost to a filing deadline.
If you are carrying an older conviction under this section, it is worth having someone look at which subsection it rested on.
Where the AUUW Law Stands Now
The version of the statute in force today rests on Illinois licensing. In 2025, the Illinois Supreme Court decided People v. Thompson and held that this statute’s restriction on unlicensed public carry, resting on the concealed carry and FOID card systems, is not facially unconstitutional under the United States Supreme Court’s decision in New York State Rifle and Pistol Association v. Bruen. The court’s reasoning turned on the fact that Illinois licenses are issued to applicants who meet fixed requirements rather than at an official’s discretion.
Illinois appellate courts have treated Thompson as binding since. As applied challenges, which depend on a particular person’s facts rather than the statute as a whole, remain available but require a developed record.
An Older Conviction Deserves Review
This area of law continues to move, and current Illinois decisions have gone against broad challenges to the statute as it reads today. That is not a reason to assume an older conviction is settled. Which subsection it rested on determines whether the reasoning in Aguilar and Burns reaches it.
How We Defend Aggravated UUW Charges in DuPage County
Testing the Basis for the Stop
These cases commonly begin with a stop, and the firearm is the center of the State’s proof. If the stop or the search that followed it was unlawful, we move to suppress what was found.
What makes this charge distinct is that the officer’s observations at the scene are not background detail. Whether the firearm was loaded, whether it was uncased, and whether it was within reach are elements the State has to prove, and they are usually recorded in a few lines written after the fact.
Challenging Whether the Firearm Was Immediately Accessible
Immediate accessibility is a factual question, and it is an element that is easy to treat as settled when it is not. A firearm in a locked trunk, in a rear cargo area, inside a closed container, or in a bag behind the back seat is not in the same position as one in a glove box or a door pocket.
A report may state a conclusion about accessibility. Photographs, the scene, and the physical layout of the vehicle sometimes show something different. We look at the actual arrangement rather than the summary of it, because that element can carry the whole factor.
Challenging the Aggravating Factor Itself
Because the factor is an element, it can be attacked directly. A FOID card that lapsed is not the same as one that was revoked. A concealed carry application already in process changes the picture the prosecutor is working from. An order of protection that falls outside the two year window does not supply the factor. A juvenile adjudication for conduct that would not have been a felony for an adult does not either.
Each of these is verifiable, and each is the kind of detail that is rarely available to an officer standing on the roadside at the moment the decision to charge gets made.
A Former Prosecutor’s Read on Factor Selection
Pat Weiland spent nearly 10 years reviewing felony files as a DuPage County Assistant State’s Attorney. He knows how that office screens a weapons case and how the choice among aggravating factors gets made early, on the strength of what an officer wrote at the scene.
That perspective is knowledge of how charging decisions get made, not access to the people who make them, and it matters most at the beginning. A license that was valid, a card that was current, or a prior that does not qualify are all facts the State can account for once they are in front of it, and it is easier to correct a factual premise while the charge is still being reviewed than after the case has settled into its shape. It is the strongest argument for bringing a lawyer in before your first court date.
Aggravated Unlawful Use of a Weapon FAQs
Yes, in every form. The base offense is a Class 4 felony carrying one to three years. A second or subsequent offense, or an offense by someone with a prior felony conviction, is a Class 2 felony carrying three to seven years. Committing the offense while wearing or possessing body armor without a valid FOID card is a Class X felony. There is no misdemeanor version of this charge.
The base charge covers prohibited weapons and unlawful carrying on its own, and it is frequently a Class A misdemeanor. This charge requires the same kind of carrying conduct plus one aggravating factor from the statutory list, and it is a felony from the outset. The factor is the entire difference.
Yes. A valid FOID card removes one factor from the list, but there are others. Being under 21 with a handgun, carrying while committing a misdemeanor drug offense, or having an order of protection entered against you in the past two years can each supply the aggravating element on its own, FOID card or not.
A currently valid concealed carry license takes the handgun versions of the loaded and unloaded factors off the table, because those factors require that no such license was issued. It does not reach the long gun versions, and it does not reach the other factors. Charges are also filed in these situations when a license was never presented at the scene or never verified, which is why that documentation needs to get to the prosecutor early.
Public Act 103-822 renamed the offense effective January 1, 2025, replacing “use” with “possession” throughout Article 24. It is the same statute, the same conduct, and the same penalties. The renaming applies retroactively to criminal records maintained by the Illinois State Police, law enforcement agencies, and clerks of court.
On the base Class 4 version, probation is an available sentence in Illinois. Where the State charges the loaded and accessible factor together with the no FOID card factor against an adult on a first offense, the statute directs a term of imprisonment of one to three years, which narrows that option significantly. Whether it applies to your case depends on exactly which factors were charged, and no outcome can be predicted from the charge alone.
It refers to whether the firearm was within your reach and available for use at the time. There is no fixed measurement. Containment and distance both matter, which is why a firearm in a locked trunk or a closed case in a cargo area is treated differently than one in a console or under a seat. Because it is a factual question, it is often one of the strongest places to challenge the aggravating factor.
Convictions resting on the subsection struck down in People v. Aguilar have been vacated, in some cases many years after sentencing, because a statute found facially unconstitutional is treated as void from the start. That path depends on which subsection your conviction rested on. Separately, a felony conviction under this statute generally is not eligible for expungement in Illinois, which is one reason the classification and the disposition deserve attention from the beginning.
Talk to a DuPage County Aggravated UUW Defense Lawyer
An aggravated UUW case is decided in large part by which factor the State attaches, and that decision is made early. Before then, a license can be verified, a card can be checked, a prior can be looked at closely, and a firearm’s actual position in the vehicle can be documented while the scene is still fresh. After a charge is filed on a particular factor, every one of those questions becomes an argument instead of a correction.
