What Is a Class 3 Felony in Illinois?
A Class 3 felony is a mid-range felony under Illinois law. It sits one step below a Class 2 and one step above a Class 4. Illinois sentencing for Class 3 felonies is governed by 730 ILCS 5/5-4.5-40, and the consequences are serious.
A conviction carries 2 to 5 years in the Illinois Department of Corrections as a standard sentence, with an extended term of 5 to 10 years available when aggravating factors apply. Fines can reach $25,000, and every prison term is followed by 1 year of mandatory supervised release. The conviction stays on your criminal record permanently unless a court later seals it.
Class 3, Third Degree, and F3 Are the Same Idea
Other states use terms like “third degree felony” or “F3” for crimes in this range. Illinois uses the “Class 3” label instead. If you have seen any of these terms applied to your case and you are being charged in Illinois, the state statute that controls your sentence is the Class 3 felony statute.
Class 3 Felony Offenses in Illinois
Many Illinois offenses carry a Class 3 felony classification. Below are the most common Class 3 charges we defend in DuPage County. Each links to a dedicated page explaining how we handle that specific charge.
Aggravated Battery
Causing great bodily harm, permanent disability, or disfigurement, or battery against a protected victim such as a peace officer, teacher, or person over 60. Governed by 720 ILCS 5/12-3.05.
Reckless Homicide
Causing death through reckless operation of a motor vehicle or other reckless conduct. Classified as a Class 3 in most cases under 720 ILCS 5/9-3.
Theft of $500 to $10,000
Theft classification in Illinois is driven by the value of what was taken. Theft in this dollar range is charged as a Class 3 felony under 720 ILCS 5/16-1.
Identity Theft ($300 to $2,000)
The dollar value of the victim’s loss determines the felony class. Identity theft in this range is a Class 3 under 720 ILCS 5/16-30.
Drug Possession and Intent to Deliver
Possession of certain controlled substances in specific weight ranges is charged as a Class 3 felony under the Illinois Controlled Substances Act.
Aggravated DUI
Most DUIs are misdemeanors, but specific aggravated DUI circumstances rise to a Class 3, including a subsequent DUI after a prior reckless homicide or aggravated DUI conviction resulting in death.
Aggravated Assault
Assault involving a firearm, assault against a peace officer, teacher, or other protected victim, or assault in certain public places is elevated to a Class 3 under 720 ILCS 5/12-2.
Forgery
Falsifying documents, checks, or signatures with intent to defraud is charged as a Class 3 felony under 720 ILCS 5/17-3.
Certain Sex Offenses
A range of sex offenses fall under Class 3 classification, including possession of child pornography (first offense) and specific sexual abuse charges. These cases also carry sex offender registration requirements.
Class 3 Felony Sentence in Illinois
Standard Sentencing Range
The standard sentence for a Class 3 felony in Illinois is 2 to 5 years in the Illinois Department of Corrections. The sentence is determinate, meaning the judge sets a fixed number of years within that range rather than an open-ended term. Judges have discretion to weigh the facts of the case, the defendant’s history, and mitigating or aggravating factors presented at the sentencing hearing.
Extended-Term Sentencing
When aggravating factors apply, the court can impose an extended-term sentence of 5 to 10 years. Common aggravators under 730 ILCS 5/5-5-3.2 include a prior Class 3 or higher felony conviction within the last 10 years, use of a firearm in the offense, the victim being over 60 years old, hate crime elements, or targeting a victim based on a protected characteristic.
The extended-term decision is made at sentencing, often based on evidence the State presents after a plea or verdict. A strong defense pushes back on these factors before they become part of the record.
Fines and Mandatory Supervised Release
On top of any prison sentence, a Class 3 felony conviction can carry fines up to $25,000. The court can also order restitution to victims when the offense caused financial loss. After release from prison, every Class 3 sentence includes 1 year of mandatory supervised release, which is Illinois’ version of parole. Violations of supervised release conditions can send you back to prison to complete the remaining term.
A Class 3 Conviction Follows You for Life
Even after the prison term and supervised release are complete, a Class 3 felony conviction shows up on background checks. That affects employment, professional licensing, firearm rights, housing applications, and your ability to qualify for certain loans. The best time to challenge the charge is at the front end, before a conviction becomes permanent.
Class 3 Felony vs. Class 2 and Class 4 in Illinois
Illinois sorts felonies into six classes. Class 3 sits in the middle of that range. Here is how it compares to the classes directly above and below it.
| Felony Class | Standard Prison Range | Extended Term | Max Fine | Common Examples |
|---|---|---|---|---|
| Class 2 | 3 to 7 years | 7 to 14 years | $25,000 | Burglary, aggravated DUI, certain drug offenses |
| Class 3 | 2 to 5 years | 5 to 10 years | $25,000 | Aggravated battery, theft $500 to $10,000, forgery |
| Class 4 | 1 to 3 years | 3 to 6 years | $25,000 | Low-level drug possession, certain DUIs, small-dollar theft |

Is a Class 3 Felony Probationable in Illinois?
In most cases, yes. A Class 3 felony is probation-eligible under Illinois law unless the specific offense carries a statutory mandatory prison term. Probation for a Class 3 can run up to 30 months. The court can also impose alternatives such as periodic imprisonment, conditional discharge, or impact incarceration for younger defendants who meet the program criteria.
First-time offenders facing non-violent Class 3 charges may qualify for the Offender Initiative Program under 730 ILCS 5/5-6-3.4. Successful completion of that program results in the charge being dismissed and no conviction appearing on the record, which preserves eligibility for expungement later.
What moves a judge toward probation over prison: a clean prior record, cooperation with the investigation, restitution where applicable, and a defense strategy that shapes the pre-sentence investigation before the hearing. Letters of support, employment verification, treatment records, and a well-prepared sentencing memorandum all make a measurable difference.
Eligibility Is Not the Same as Being Granted Probation
Many Class 3 charges are probation-eligible on paper. That does not mean the prosecutor will agree to probation or that a judge will impose it. DuPage County prosecutors often push for prison time even on probation-eligible charges, which is why the defense strategy in the weeks leading up to sentencing matters more than most people realize.
Can a Class 3 Felony Be Expunged in Illinois?
A Class 3 felony conviction cannot be expunged. Expungement completely erases a record and is reserved for arrests that did not result in conviction, acquittals, or certain dismissals. A conviction is permanent.
What is available for many Class 3 convictions is sealing under 20 ILCS 2630/5.2. A sealed record is hidden from most public background checks, though law enforcement and certain licensed employers can still see it. Sealing generally requires a waiting period of 3 years after completing the sentence.
Not every Class 3 is eligible for sealing. Sex offenses, DUI convictions, domestic battery, and certain violent crimes are excluded by statute. The best way to preserve expungement as an option is to avoid the conviction in the first place, either through a dismissal, a not-guilty verdict, or successful completion of a diversion program like the Offender Initiative Program.
The DuPage County Class 3 Felony Process
Class 3 felony cases filed in DuPage County are typically heard in the 18th Judicial Circuit Court in Wheaton. The path most cases follow is outlined below, though timelines vary and many cases are resolved before reaching trial.
How a DuPage County Class 3 Felony Case Moves
Every case is different. Some resolve in weeks through negotiation. Others take months and go to trial. The steps below reflect the typical path.
Step 1 — Arrest and Bond Hearing
Pretrial release conditions are set under 725 ILCS 5/110-5. Having an attorney present at the first hearing influences whether you are released and on what terms.
Step 2 — Preliminary Hearing or Grand Jury Indictment
The State must establish probable cause that you committed the charged offense. This is the first real opportunity to challenge the case.
Step 3 — Arraignment
The formal charges are read and you enter a plea. A not-guilty plea preserves every defense option going forward.
Step 4 — Discovery
The defense receives access to all evidence the State plans to use, including police reports, witness statements, forensic results, and any video or audio evidence.
Step 5 — Pre-Trial Motions
The defense can file motions to suppress evidence obtained through unlawful searches, motions to dismiss based on probable cause failures, or motions to exclude prejudicial evidence.
Step 6 — Plea Negotiations or Trial
Most cases resolve through negotiation. When the evidence or the offered terms are unacceptable, the case proceeds to trial before a judge or jury.
Step 7 — Sentencing
If there is a conviction or a plea, the judge imposes a sentence within the statutory range, weighing mitigating and aggravating factors presented at the hearing.
Defense Strategies for Class 3 Felony Charges
There is no formulaic defense to a Class 3 felony. The strategy depends on the specific offense, the strength of the State’s evidence, and how the arrest and investigation were conducted.
Common angles include challenging the legality of the traffic stop or search, attacking the chain of custody on physical evidence, raising constitutional violations such as Miranda failures or Fourth Amendment breaches, impeaching witness credibility, and demonstrating the absence of intent where intent is a required element of the charge.
When the evidence is strong and a conviction is likely, the defense shifts to mitigation. The goal becomes framing the sentencing hearing so a judge grants probation instead of prison, or reducing the exposure through plea negotiation.

Class 3 Felony FAQs
It is a mid-level felony. Less serious than Class X, Class 1, or Class 2, but more serious than a Class 4 or any misdemeanor. A conviction carries prison exposure, a permanent record, and long-term consequences for employment, housing, and firearm rights.
In most cases, yes. First-time offenders charged with probation-eligible Class 3 offenses often qualify, and a well-prepared sentencing presentation can move a judge toward probation. Eligibility is not a guarantee, though. Prosecutors can still argue for prison.
Many can, under 20 ILCS 2630/5.2, after a 3-year waiting period from the end of the sentence. Sex offenses, DUI, domestic battery, and certain violent crimes are excluded from sealing eligibility.
Illinois does not have a broad three-strikes law like some states. However, prior felony convictions significantly increase exposure on a new case. A prior Class 3 or higher within the last 10 years can trigger extended-term sentencing of 5 to 10 years on a new Class 3.
