Second DUI
Generally a Class A misdemeanor unless another aggravated-DUI provision applies.
A second DUI and a felony DUI are not necessarily the same thing.
Prior DUI violations can increase the charge, while other circumstances can independently result in aggravated DUI.
Quick Answers
Generally a Class A misdemeanor unless another aggravated-DUI provision applies.
Aggravated DUI and a Class 2 felony.
Class 2 felony; a conviction as charged requires imprisonment.
Class X felony with an ordinary 6-to-30-year sentencing range.
A DUI charge becomes significantly more serious when a person has prior DUI violations or when additional circumstances result in the felony charge of aggravated DUI.
A second DUI in Illinois is generally still a misdemeanor unless an independent aggravating factor makes the offense an aggravated DUI. A third or subsequent DUI is an aggravated DUI and a felony. When determining whether a DUI is a second, third or subsequent offense, prior DUI dispositions can matter even when the prior case resulted in court supervision rather than a conviction.
For someone charged with a second, third, fourth or subsequent DUI, the first step should be determining exactly what the State is alleging, which prior offenses legally count, and what sentencing and driver’s-license consequences actually apply.
Illinois refers to felony DUI as aggravated DUI.
Under 625 ILCS 5/11-501(d), a DUI can become aggravated DUI in several different ways. One of the most common is a third or subsequent DUI offense.
But prior DUI offenses are not the only way a DUI becomes a felony.
Depending on the circumstances, aggravated DUI charges can also arise when a DUI involves serious bodily injury or death, certain child passengers, driving while suspended or revoked for specified prior offenses, driving without a valid license or permit, driving without required liability insurance, operating certain vehicles with passengers, and other circumstances specifically identified by Illinois law.
That distinction matters. A person facing a felony DUI charge should know why the State claims the offense is aggravated, because the alleged aggravating factor is part of what the prosecution must establish.
Generally, no.
A second DUI is ordinarily a Class A misdemeanor, unless a separate aggravating circumstance elevates the charge to aggravated DUI.
Although the offense ordinarily remains a misdemeanor, the consequences are substantially different from a first DUI. A person charged with a second DUI is not eligible to receive court supervision. If convicted, the driver’s license will be revoked. The length of that revocation depends on the person’s prior conviction history and when the prior conviction occurred.
Illinois law also imposes mandatory sentencing requirements for a second DUI. A second DUI conviction carries a mandatory minimum sentence of either:
Additional mandatory penalties can apply depending on the circumstances. For example, a second DUI involving a BAC of .16 or greater carries additional mandatory minimum penalties.
A second DUI can also become aggravated DUI if an independent felony-enhancing circumstance applies.
For many people charged with a second DUI, the inability to receive supervision and the possibility of losing driving privileges through a revocation can be every bit as significant as the mandatory criminal penalties.
A third DUI offense is an aggravated DUI and a Class 2 felony.
This is an important dividing line under Illinois DUI law. A person who may previously have faced misdemeanor DUI prosecutions can now face felony prosecution and the possibility of a prison sentence.
Prior court supervision for DUI can count when determining whether the present offense is a third DUI. The criminal classification therefore does not necessarily depend on the person having two prior DUI convictions.
Additional mandatory penalties can apply when aggravating circumstances are present.
For example, Illinois law provides additional mandatory penalties for a third DUI when the person’s alcohol concentration was .16 or greater.
The driver’s-license consequences require a separate analysis because Secretary of State revocation periods are based on DUI convictions, rather than simply the number of DUI offenses used to classify the criminal charge.
For example, a person whose record consists of one prior DUI supervision and one prior DUI conviction may be facing a third DUI criminal charge, but a conviction in the new case would generally constitute the person’s second DUI conviction for purposes of the Secretary of State’s conviction-based revocation schedule. If that second conviction falls within the applicable 20-year period, the minimum revocation is generally five years.
By contrast, a person receiving a third DUI conviction faces a minimum 10-year revocation.
The fact that a third DUI is a felony does not eliminate the need to examine the underlying DUI charge. The State must still prove the current DUI offense and the facts necessary to establish the felony classification.
A fourth DUI offense is an aggravated DUI and is generally classified as a Class 2 felony.
The sentencing consequences become substantially more restrictive at this level. Illinois law provides that a person convicted of a fourth DUI is not eligible for probation or conditional discharge. As charged, that means a conviction requires a sentence of imprisonment rather than probation.
The driver’s-license consequences again depend on the number of DUI convictions on the person’s record. A fourth DUI conviction results in lifetime revocation of driving privileges.
A lifetime revocation does not necessarily mean that a person can never obtain any driving relief. Illinois currently permits a person with four or more DUI convictions to apply for a Restricted Driving Permit after serving the required portion of the revocation and satisfying the applicable requirements. If relief is granted following a lifetime revocation, lifetime BAIID requirements apply.
A fifth DUI offense is an aggravated DUI and a Class 1 felony.
Illinois law also provides that a person convicted of a fifth DUI is not eligible for probation or conditional discharge.
At this level, both the criminal case and the driver’s-license consequences require careful attention. The sentencing exposure is substantially greater than in a misdemeanor DUI case. If the record also includes four or more DUI convictions, the person faces lifetime revocation of driving privileges.
A sixth or subsequent DUI offense is an aggravated DUI and a Class X felony.
A Class X felony ordinarily carries a sentencing range of 6 to 30 years in the Illinois Department of Corrections, subject to any other sentencing provisions applicable to the particular case.
The person’s prior DUI history, the circumstances of the current offense, any additional aggravating factors and the evidence establishing the prior offenses can therefore have enormous consequences.
It is possible to face aggravated DUI without having two prior DUI offenses.
Illinois law identifies numerous circumstances that can elevate an otherwise misdemeanor DUI to felony aggravated DUI.
Examples include certain DUI offenses involving:
The classification and potential penalties vary depending on the particular aggravating circumstance.
For that reason, simply being told that a case is an “aggravated DUI” does not provide enough information to determine the actual sentencing exposure.
The specific subsection charged matters.
Generally, yes.
When determining whether an offense constitutes a second, third or subsequent DUI, Illinois law can include qualifying prior offenses under the law of another state as well as certain similar local-ordinance and military-installation offenses.
This can become particularly important when a person’s driving history includes an older DUI from Wisconsin, Indiana, Michigan or another state.
The prior offense should still be examined to determine what the offense actually was and whether it qualifies as a similar prior violation under Illinois law.
In a multiple-DUI prosecution, the defendant’s prior DUI history can determine whether the current offense is a misdemeanor or felony and can affect the potential sentence.
Illinois does not simply disregard a prior DUI because the defendant received court supervision rather than a conviction. A prior DUI supervision can count when determining whether the current prosecution is a second, third or subsequent DUI offense.
A review of the alleged prior record may therefore include questions such as:
Illinois law specifically addresses proof of prior DUI convictions, including the admissibility of a certified driving abstract as proof of a prior conviction.
A defense review should therefore consider not only the evidence from the current arrest but also the prior record the prosecution intends to use to establish repeat-offender status.
The existence of prior DUI offenses or another aggravating circumstance does not establish that the person committed the current DUI.
The current case still has to be proven.
Depending on the circumstances, that review may include:
Did the officer have a lawful basis to stop the vehicle?
Can the State prove that the defendant drove or was in actual physical control of the vehicle?
This can become particularly important in cases involving parked vehicles, crashes where the officer did not observe the driving, or situations where more than one person could have been driving.
Police reports often rely on observations such as odor of alcohol, bloodshot or glassy eyes, speech, balance, demeanor and admissions.
Those observations should be compared with video and the surrounding circumstances rather than simply accepted from the report.
The conditions under which field sobriety tests were administered can matter, including the instructions given, surface conditions, footwear, weather, physical limitations and whether the officer administered the tests consistently with accepted procedures.
Breath-test cases may require examination of the testing procedure, observation period, machine records, operator compliance and other issues affecting admissibility or reliability.
Cases involving hospital blood, police-requested blood draws or urine testing can present different evidentiary and scientific issues.
Squad-car, body-camera, booking-room and other video can provide evidence that either supports or contradicts descriptions contained in police reports.
The potential consequences may be much greater in a felony or multiple-DUI prosecution, but the State still has the burden of proving the current DUI.
The number of DUI offenses used to classify a criminal DUI charge and the number of DUI convictions used by the Secretary of State are not always the same.
That distinction is particularly important when the person’s record includes court supervision.
A prior DUI supervision can count toward determining whether a new criminal charge is a second, third or subsequent DUI, while supervision itself does not constitute a DUI conviction that causes a conviction-based driver’s-license revocation.
The statutory summary suspension arising from the new arrest is also separate from both the criminal prosecution and any revocation resulting from a DUI conviction.
For DUI convictions, the Illinois Secretary of State generally imposes the following minimum revocation periods:
This means two defendants both charged criminally with a third DUI can potentially face different driver’s-license consequences based on how their prior DUI cases were disposed of.
The rules governing eventual reinstatement or restricted driving privileges depend on the person’s complete driving record.
Drivers with multiple alcohol- or drug-related incidents generally face a formal Secretary of State hearing when seeking driving relief. Depending on the record, BAIID requirements may also apply before full reinstatement is possible.
Because the criminal case, statutory summary suspension and Secretary of State revocation operate under different rules, all three should be evaluated separately.
Evaluating a felony or repeat-DUI charge requires looking at both the evidence from the current arrest and the history being used to increase the charge or potential penalties.
That review may include:
A prior DUI disposition can affect the classification of the current criminal charge without necessarily having the same effect on the Secretary of State’s revocation calculation. Understanding exactly what happened in each prior case is therefore an important part of evaluating the current prosecution.
Frequently Asked Questions
These general answers cannot replace a review of the facts, prior DUI dispositions, driving history, and charging documents in an individual case.
No. A second DUI is generally a Class A misdemeanor unless a separate aggravating circumstance makes the offense an aggravated DUI. A person charged with a second DUI is not eligible for court supervision.
Yes. A third DUI offense is aggravated DUI and a Class 2 felony. Prior DUI court supervision can count when determining whether the current offense is a third DUI.
A fourth DUI offense is generally a Class 2 felony. Illinois law provides that a person convicted of a fourth DUI is not eligible for probation or conditional discharge, meaning a conviction as charged requires imprisonment.
A fifth DUI offense is a Class 1 felony, and Illinois law provides that a person convicted of a fifth DUI is not eligible for probation or conditional discharge.
A sixth or subsequent DUI offense is a Class X felony. The ordinary Class X sentencing range is 6 to 30 years in the Illinois Department of Corrections.
Generally, yes. Illinois law permits qualifying similar DUI offenses from other states and certain other jurisdictions to count when determining whether a current DUI is a repeat offense. The particular prior offense should still be reviewed to determine whether it qualifies under Illinois law.
Yes. Although court supervision is not a conviction, a prior DUI supervision can count when determining whether a later DUI prosecution is a second, third or subsequent DUI offense. That is different from the Secretary of State's conviction-based revocation calculation. A supervision does not become a DUI conviction merely because it can be counted as a prior DUI offense for purposes of the criminal statute.
Yes. Multiple prior DUI offenses are only one basis for aggravated DUI. Other circumstances identified by Illinois law can make a DUI a felony even without two prior DUI offenses.
Potentially. Eligibility depends on the person's complete driving record and applicable revocation. Drivers with multiple alcohol- or drug-related incidents generally must proceed through a formal Secretary of State hearing, and BAIID requirements may apply. Illinois currently permits certain drivers with four or more DUI convictions to seek an RDP after serving the required portion of a lifetime revocation, subject to the statutory and administrative requirements.
No. The prosecution must still prove the current DUI. Issues involving the stop, driving or actual physical control, field sobriety testing, chemical testing, video and other evidence may remain important even when the prior DUI history is not disputed.
