You already know what a DUI arrest looks like. You have been to court for this before. What you may not know is that Illinois treats the fourth one as a different kind of case, and the difference is not a matter of degree.
On a third DUI, a judge still has a choice. On a fourth, the law takes that choice away, and it stays taken away on a fifth and a sixth. This page covers all three.
Is a Fourth DUI a Felony in Illinois?
Yes. A fourth DUI is charged as an aggravated DUI, a Class 2 felony, under 625 ILCS 5/11-501. No crash, no injury, and a blood alcohol level barely over the limit do not change that. Your three prior dispositions set the class of the charge.
That much it shares with a third offense. Here is where the two stop looking alike.
Probation is not available
The statute that makes a fourth DUI a Class 2 felony, 625 ILCS 5/11-501(d)(2)(C), adds seven words that a third offense does not carry: probation or conditional discharge may not be imposed. A judge who wants to keep you out of prison has no lawful way to do it on a conviction. That is why the case has to be fought before it gets to sentencing.
Can You Be Held Until Your Trial?
Illinois no longer uses cash bail. Most people charged with a crime have to be released before trial, and a judge cannot hold someone simply because the charge is serious or the record is long.
A fourth DUI is one of the exceptions. Under 725 ILCS 5/110-6.1(a)(1), the State can ask a judge to detain a person charged with a felony, other than a forcible felony, that requires a prison sentence with no probation available on conviction. That is a fourth DUI. A third offense does not qualify, because probation is still on the table for a third.
Detention is not automatic. The State has to file a petition and prove its case at a hearing, and you have the right to a lawyer at that hearing. But the exposure is real, and it is decided at your first court appearance, not months later. If you have been through three of these and were released each time, do not assume the fourth will go the same way.
Prison Is Mandatory After a Fourth DUI Conviction
Illinois sentencing law sets the range for a Class 2 felony at three to seven years in the Illinois Department of Corrections, followed by one year of mandatory supervised release under 730 ILCS 5/5-8-1.
On a third DUI, that same range applies, but the judge can order up to four years of probation instead, with a minimum of ten days in jail or 480 hours of community service attached. On a fourth, that door is closed by statute.
| Third DUI | Fourth DUI | |
|---|---|---|
| Felony class | Class 2 | Class 2 |
| Probation available | Yes, up to 4 years | No, barred by statute |
| Prison range | 3 to 7 years | 3 to 7 years |
| Fines | Up to $25,000 | Up to $25,000 |
| BAC of 0.16% or higher | Minimum 90 days jail and $2,500 fine | Minimum $5,000 fine |
| Passenger under 16 | $25,000 fine and 25 days community service | $25,000 fine and 25 days community service |
| License consequence | Revoked at least 10 years | Revoked for life |

What a Conviction Costs Beyond the Sentence
The table above is the part a judge reads out. It is not the part that lasts longest.
Your vehicle registration is suspended, and in some cases the vehicle itself can be taken. The conviction never comes off your record, because Illinois excludes DUI from both expungement and sealing, so a DUI stays on your Illinois record permanently. And the felony itself becomes a fact you carry into every job application, every rental application, every professional license renewal, most government benefit programs, college financial aid, and any question about owning a firearm.
Clients almost never ask about this part in the first meeting. They ask about prison. Then the case ends and the rest of it starts.
Two Facts That Add Mandatory Fines
Neither of these can be argued down at sentencing. They attach automatically.
A blood alcohol concentration of 0.16% or higher adds a mandatory minimum fine of $5,000. Note what changed from the third offense: on a third, a high reading adds 90 days of mandatory jail. On a fourth, the jail term is already mandatory, so the statute adds money instead.
A passenger under the age of 16 in the vehicle adds a mandatory $25,000 fine and 25 days of community service in a program that benefits children.
What Counts as a Prior DUI
This is where people are most often wrong about their own record, and being wrong about it is expensive.
Illinois has no lookback period. A DUI from 1997 counts exactly as much as one from last spring. There is no window that closes, no number of clean years that erases a prior.
Court supervision counts. Many people who took supervision on a first offense believe it left them with nothing on the record. For the purpose of the criminal case, it does not work that way. In People v. Sheehan, 168 Ill. 2d 298 (1995), the Illinois Supreme Court held that a completed DUI supervision can still raise a later charge. That holds even though court supervision is not a conviction and never appears on your record as one.
The substance does not matter. An alcohol DUI counts toward a drug charge, and a cannabis DUI counts toward an alcohol charge.
Out-of-state convictions count. A DUI in Indiana or Wisconsin counts toward the Illinois charge and toward the lifetime revocation, and it can count even when it does not appear on your Illinois driving record.
So the arrest you are calling a third may be a fourth. Bring every disposition you can find to the first meeting, including the ones you think were dismissed. Counting them correctly is the first thing we do.
Losing Your License for Life, and the One Way Back
Before Any of That, the Suspension
The revocation below follows a conviction. Something happens well before it. The statutory summary suspension is administrative, automatic, and takes effect on the 46th day after your arrest, whether or not your case has moved at all.
If any prior DUI disposition falls within the last five years, a failed test suspends you for one year and a refusal for three. If all three of your priors are older than five years, you may still count as a first offender for this one purpose, even while facing a fourth offense felony in the criminal case. The monitoring device driving permit that lets first offenders keep driving during a suspension is not available with a recent prior.
Day 46 is your first deadline
The suspension takes effect on the 46th day after your arrest. A petition to rescind it has to be filed early enough to be heard before that day, or the suspension posts to your record no matter how the criminal case turns out. This is the one deadline in your case that you can lose by doing nothing at all.
Revocation Is Not Suspension
A fourth DUI does not suspend your license. It revokes it, permanently, under 625 ILCS 5/6-208. A suspension ends on a date. A lifetime revocation has no date.
Full reinstatement is also off the table. If any of your four DUI convictions happened on or after January 1, 1999, Illinois will not restore your full driving privileges. Not after five years, not after twenty. The most the Secretary of State can grant is a restricted permit, and it stays restricted for the rest of your life.
Illinois did soften the older rule, which barred any relief at all. Under the current administrative rules at 92 Ill. Adm. Code 1001.420(q), a person with four or more DUI dispositions can ask for a lifetime restricted driving permit. Asking is not getting. The requirements are strict, the burden is on you, and one of them is residency: the lifetime permit is for Illinois residents, and a person who moves out of state and later returns has the lifetime revocation reimposed.
The path to a lifetime restricted driving permit
Five steps stand between a lifetime revocation and limited driving privileges, and they run in order. Every one of them is mandatory.
Wait five years
The clock runs from your most recent order of revocation or your release from incarceration on the most recent DUI, whichever comes later. Not from the arrest, and not from the conviction.
Prove three years of abstinence
You must show at least three continuous years free of alcohol and of any non-prescribed drug, documented, not asserted.
Complete evaluation and treatment
An alcohol and drug evaluation, and every treatment recommendation that comes out of it.
Win a formal hearing
A formal hearing before the Secretary of State, where you carry the burden of showing you are not a risk on the road.
Install a BAIID, permanently
A breath alcohol ignition interlock device on every vehicle registered in your name, at your expense, for the rest of your driving life.
One more thing about that permit. A DUI conviction while you hold it cancels it, and it bars you from applying for driving relief again. There is no fifth chance built into this system. The permit is the ceiling, not a step toward getting an Illinois driver’s license reinstated in full.
Driving on a revoked license is its own charge under 625 ILCS 5/6-303, and it climbs with each violation. People facing a fourth DUI frequently pick up that charge while the DUI case is still open, which is the worst possible time for it.
Facing a DUI with multiple priors?
A fourth offense turns on how the State proves your priors, and those records do not always hold up. Your first consultation is free.
How We Defend a Fourth DUI
A fourth DUI case has two halves, and most people only think about one of them.
The current arrest
Everything that works in an ordinary DUI still works here, and it matters more. Did the officer have a lawful reason for the stop? Was the breath machine calibrated, and was it run correctly? Were the field sobriety tests given the way the standards require? Was there a warrant where one was needed? Evidence that comes out of a bad stop can come out of the case.
The three priors
The State has to prove the priors too, with certified court records, and those records are not always right. They name the wrong person. They double-count a single arrest. They mishandle an out-of-state disposition or one that was amended. If a prior does not hold up, the charge you are facing may not be a fourth offense.
That second half is where a fourth DUI is genuinely different from the cases that came before it. The gap between a non-probationable fourth and a probationable third is the difference between a mandatory prison sentence and a judge with options. It is worth every hour spent on it.
Patrick J. Weiland spent nearly ten years as an Assistant State’s Attorney in DuPage County, where he supervised the felony trial division, before he began defending these cases. That background gives him no influence over the State’s Attorney or the court. What it gives him is a working knowledge of how the State assembles a felony DUI file, including how it proves the priors and where that proof tends to be thin.
Fifth and Sixth Offenses
The statute keeps climbing, and probation stays unavailable at every step.
| Offense | Felony class | Prison range | Probation |
|---|---|---|---|
| Fourth | Class 2 | 3 to 7 years | Not available |
| Fifth | Class 1 | 4 to 15 years | Not available |
| Sixth or subsequent | Class X | 6 to 30 years | Not available |
Class X is the most serious felony classification in Illinois short of first degree murder. It is the same class the State uses for armed robbery and for delivery of large quantities of a controlled substance.
Everything else on this page applies to a fifth and a sixth offense without change. The license is revoked for life, and the five year wait and three year abstinence requirement for a restricted permit work the same way. The mandatory fine for a blood alcohol concentration of 0.16% or higher and the mandatory fine for a passenger under 16 both attach the same way. Because all three offenses are non-probationable, all three are detention-eligible under 725 ILCS 5/110-6.1(a)(1), so the question of whether you are held before trial arises at a fifth and a sixth exactly as it does at a fourth.
The defense also works the same way, and the second half of it matters more with each offense. On a sixth, the State has to prove five prior dispositions, some of them likely decades old. Every one of them is a record that has to hold up.

Frequently Asked Questions
Yes. The Illinois Supreme Court held in People v. Sheehan that a completed DUI supervision can raise a later charge. Supervision keeps a conviction off your record, but it still counts when the State is counting offenses. This catches more people than any other rule on this page.
Yes. A DUI from another state counts toward the Illinois charge and toward the lifetime revocation, and it can count even when it does not appear on your Illinois driving record.
There is no lookback period for the criminal charge. Every prior DUI counts for life, regardless of how long ago it happened. The statutory summary suspension is the exception: it uses a five year window, which is why you can be a fourth offender in the courtroom and a first offender at the Secretary of State on the same arrest.
Only if the State agrees. A judge cannot amend the charge on their own, so a reduction to reckless driving, sometimes called a wet reckless, is a negotiated outcome rather than something you can ask the court for. It is a harder negotiation on a felony than on a misdemeanor. Worth knowing either way: a reckless driving conviction reduced from a DUI still counts as a prior DUI disposition if you are charged again.
No. Illinois law reaches actual physical control of a vehicle, not just driving it, which is why people are charged after being found parked or asleep in a car that never moved. Whether the State can actually prove physical control is often one of the live questions in the case.
Possibly, on a restricted permit. You can apply after five years have passed from your most recent revocation order or your release from incarceration, whichever is later. You must also show three continuous years of abstinence, complete evaluation and treatment, live in Illinois, win a formal hearing, and keep a breath alcohol ignition interlock device on every vehicle registered in your name for the rest of your driving life.
A commercial driver’s license is disqualified for life after a second DUI conviction, so by a fourth the CDL is already gone. That disqualification is separate from the lifetime revocation of your regular driving privileges, and neither one cancels the other.
Yes. A felony conviction ends your eligibility for an Illinois FOID card and makes possessing a firearm a federal offense under 18 U.S.C. § 922(g)(1). The offense being a driving offense changes nothing, because gun rights turn on the felony classification rather than on what the felony was.
It can. A single DUI is usually not the kind of offense that triggers removal on its own, but a felony conviction and a record of repeat offenses can affect applications for relief, good moral character findings, and naturalization. How a DUI affects immigration status turns on the specific relief being sought and on the full record, so if you are not a US citizen, get an immigration attorney working alongside your criminal defense.
