Quick Answer: In Illinois, a first-offense DUI triggers an automatic statutory summary suspension of 6 months if you submitted to chemical testing, or 12 months if you refused. A second or subsequent DUI within 5 years results in a 12-month suspension for submitting and a 3-year suspension for refusing. These timelines run separately from any court-ordered revocation that follows a conviction.
Key Takeaways
- Illinois imposes two distinct license penalties after a DUI: a statutory summary suspension (automatic, administrative) and a revocation (court-ordered, follows conviction).
- First-offense suspension: 6 months for submitting to a chemical test, 12 months for refusing.
- Second or subsequent offense within 5 years: 12 months for submitting, 3 years for refusing.
- A DUI conviction triggers a separate license revocation, which has no fixed end date and requires a formal Secretary of State hearing to reverse.
- Drivers may petition for a Monitoring Device Driving Permit (MDDP) during a summary suspension, which requires an ignition interlock device.
- Reinstatement fees through the Illinois Secretary of State currently run $500 for a DUI-related revocation.
- Driving on a suspended or revoked license after a DUI is a separate criminal offense in Illinois that can result in additional suspension time and jail.
- A DUI suspension can raise auto insurance premiums significantly and may trigger an SR-22 filing requirement.
What Is a DUI License Suspension in Illinois?
A DUI license suspension in Illinois is an automatic, temporary removal of driving privileges triggered by a DUI arrest, specifically by failing or refusing a chemical test. It is called a statutory summary suspension and takes effect 46 days after the driver receives a Notice of Statutory Summary Suspension, regardless of whether a criminal conviction follows.
This administrative penalty is separate from any criminal case outcome. Even if charges are later reduced or dismissed, the summary suspension typically remains in effect unless the driver successfully challenges it at a summary suspension hearing.
Key distinction: A suspension has a defined end date. A revocation does not. Understanding which one applies to your situation is the first step in planning your path back to full driving privileges.
How Long Does a DUI Suspension Last in Illinois?
The length of a DUI license suspension in Illinois depends on two factors: whether it is a first or subsequent offense within 5 years, and whether the driver submitted to or refused chemical testing.
| Offense History (within 5 years) | Submitted to Test | Refused Test |
|---|---|---|
| First offense | 6 months | 12 months |
| Second or subsequent offense | 12 months | 3 years |
These are the mandatory minimums under 625 ILCS 5/11-501.1 (Illinois Vehicle Code). The clock starts 46 days after the Notice of Statutory Summary Suspension is served, not on the date of arrest.

First Offense DUI License Suspension in Illinois: How Long?
For a first-time DUI offender in Illinois, the statutory summary suspension is 6 months if the driver took the chemical test and registered a BAC of 0.08 or higher (or had any trace of cannabis or controlled substance). If the driver refused testing entirely, the suspension extends to 12 months.
This is the administrative penalty only. A conviction in criminal court adds a separate license revocation on top of it. For a complete breakdown of what a first arrest means for your driving record, see first offense DUI in Illinois: know the charges you face.
Common mistake: Many first-time offenders assume the 6-month suspension begins at arrest. It does not. The 46-day window after the notice is served gives drivers time to request a hearing or apply for a permit before driving privileges are actually cut off.
Second DUI Offense License Suspension in Illinois: How Long?
A second DUI offense within 5 years triggers a 12-month suspension for submitting to a chemical test and a 3-year suspension for refusing. Illinois counts prior DUI-related suspensions, not just convictions, when calculating whether an offense is a “second” for suspension purposes.
If a second DUI results in a conviction, the court-ordered revocation that follows is also longer and harder to reverse than a first offense. Repeat offenders face a mandatory minimum 5-year revocation period before they are eligible to seek reinstatement.
Illinois DUI Suspension vs. Revocation: What Is the Difference?
A suspension is temporary and ends automatically on a set date. A revocation is indefinite and requires formal action to restore driving privileges.
Here is how the two penalties differ in practice:
- Suspension: Triggered by the arrest and chemical test result. Ends on a specific date. No hearing required to restore privileges once the period ends (assuming fees are paid and any required programs are completed).
- Revocation: Triggered by a DUI conviction in court. Has no automatic end date. Requires a formal or informal hearing before the Illinois Secretary of State to get driving privileges back.
A driver can face both at the same time. The summary suspension runs first; the revocation kicks in after a guilty verdict or plea. For more on what happens when a license is permanently cancelled, see demystifying lifetime driver license revocation in Illinois.
Can You Get Your License Back Early After a DUI Suspension in Illinois?
Early termination of a statutory summary suspension is possible, but only through a successful court petition. A driver must file a petition to rescind the summary suspension within the 46-day window before it takes effect. The hearing is held in the same court where the DUI case is pending.
Grounds for rescission include:
- The officer lacked reasonable grounds to believe the driver was under the influence.
- The driver was not properly warned of the consequences of refusing or failing the test.
- The test was not administered properly under Illinois law.
If the petition is denied or not filed in time, the suspension runs its full course. There is no administrative appeal process after the 46-day window closes for most drivers.
Can You Get a Restricted License During a DUI Suspension in Illinois?
Yes. Illinois offers a Monitoring Device Driving Permit (MDDP) for most first-time DUI offenders during their summary suspension. The MDDP allows limited driving anywhere, at any time, as long as a Breath Alcohol Ignition Interlock Device (BAIID) is installed in the vehicle.
Key eligibility rules:
- Available to first-time summary suspension recipients only (not second or subsequent offenses within 5 years).
- The MDDP is not available if the DUI involved a death or great bodily harm.
- The driver must apply through the Illinois Secretary of State and pay associated fees.
- Driving any vehicle without the BAIID during the MDDP period is a separate criminal offense.
Second-offense drivers are not eligible for the MDDP and must serve the full suspension without driving privileges.
Do You Need an Ignition Interlock Device in Illinois After a DUI?
Yes, in most cases. Any driver who receives an MDDP during a summary suspension must install a BAIID (Breath Alcohol Ignition Interlock Device) on every vehicle they drive. The device requires the driver to blow a clean breath sample before the car will start and at random intervals while driving.
After a DUI conviction and revocation, an ignition interlock device is also typically required as a condition of any restricted driving permit issued during the revocation period. Illinois law mandates BAIID use for all DUI offenders seeking reinstatement after a second or subsequent conviction.
The cost of BAIID installation and monthly monitoring fees is the driver’s responsibility. These costs are separate from reinstatement fees.
What Happens If You Drive on a Suspended License After a DUI in Illinois?
Driving on a DUI-related suspended license is a criminal offense in Illinois, not just a traffic ticket. Under 625 ILCS 5/6-303, a first violation is a Class A misdemeanor, which carries up to 364 days in jail and fines up to $2,500. More importantly, it adds an additional suspension period on top of the existing one.
If the original suspension was DUI-related, the additional penalty is a mandatory minimum 30-day jail sentence for a first conviction of driving on a suspended license. Repeat violations escalate to felony charges.

How Much Does It Cost to Reinstate a License After a DUI in Illinois?
Reinstating a driver’s license after a DUI-related revocation in Illinois costs $500, paid to the Illinois Secretary of State. This fee applies to DUI revocations specifically and is higher than the standard reinstatement fee for other offenses.
Additional costs to budget for:
- BAIID installation: Approximately $70,$150 upfront (estimate; varies by provider).
- BAIID monthly monitoring: Approximately $60,$80 per month (estimate; varies by provider).
- SR-22 insurance filing: Required for a set period; costs vary by insurer.
- Alcohol/drug evaluation and treatment programs: Required before a reinstatement hearing; costs vary.
For a full overview of the reinstatement process, see the driver’s license reinstatement guide.
What Documents Do You Need to Reinstate Your License After a DUI Suspension in Illinois?
Before the Illinois Secretary of State will restore driving privileges after a DUI revocation, the driver must typically provide:
- Proof of completed alcohol/drug evaluation (by a state-approved evaluator).
- Proof of completed treatment or education program, if recommended.
- Proof of BAIID installation (if required for the permit sought).
- SR-22 certificate of insurance from an Illinois-licensed insurer.
- Payment of the $500 reinstatement fee.
- A formal or informal hearing request, depending on the length of revocation.
Informal hearings are available at Secretary of State facilities for drivers with a single DUI conviction. Drivers with multiple DUI convictions or longer revocation periods must attend a formal hearing before a hearing officer. For less complex cases, an informal hearing may be sufficient.
How to Appeal a DUI License Suspension in Illinois
The formal process for challenging a DUI summary suspension is a petition to rescind, filed in circuit court within 46 days of receiving the notice. This is not a standard appeal, it is a civil hearing where the driver bears the burden of proving the suspension was improper.
Steps in the process:
- File a written petition to rescind in the court where the DUI case is pending.
- The court schedules a hearing, typically within 30 days of filing.
- The driver (or their attorney) presents evidence challenging the lawfulness of the stop, the test administration, or the officer’s reasonable grounds.
- If the court grants the petition, the suspension is rescinded. If denied, the suspension proceeds on its original timeline.
Missing the 46-day window eliminates the option to contest the suspension in most cases. Given the stakes, consulting with an attorney before that deadline is strongly advisable. For a broader look at the DUI process, see navigating the DUI process in Illinois: a complete guide.
Does a DUI Suspension Affect Your Car Insurance in Illinois?
Yes, significantly. A DUI-related suspension or conviction in Illinois typically causes auto insurance premiums to increase substantially. Insurers treat a DUI as a high-risk indicator, and many will cancel a policy or refuse renewal after a conviction.
Additionally, Illinois requires DUI offenders to file an SR-22 certificate (a form of high-risk insurance verification) with the Secretary of State as a condition of reinstatement. The SR-22 requirement typically lasts 3 years from the date of reinstatement. Drivers must maintain continuous SR-22 coverage during that period; a lapse restarts the clock and can trigger another suspension.
FAQ: How Long Is a DUI License Suspension in Illinois?
Q: Does the 6-month suspension start at arrest or at conviction? A: Neither. It starts 46 days after the Notice of Statutory Summary Suspension is served, which is usually shortly after the arrest. It is administrative, not tied to the criminal conviction date.
Q: Can I drive at all during a DUI summary suspension in Illinois? A: First-time offenders may apply for a Monitoring Device Driving Permit (MDDP), which allows unrestricted driving with a BAIID installed. Second-offense drivers within 5 years are not eligible and may not drive at all during the suspension.
Q: What if I refused the breathalyzer, is my suspension really 12 months? A: Yes, for a first offense. Refusing chemical testing in Illinois triggers a 12-month summary suspension, which is double the 6-month penalty for failing the test. The refusal is also admissible as evidence in the criminal DUI case.
Q: Does a DUI suspension show up on my driving record permanently? A: Yes. Illinois maintains a permanent driving record. A DUI conviction and any related suspensions or revocations remain on the record indefinitely and can affect future sentencing, insurance, and professional licensing.
Q: Can the court extend my suspension beyond the standard period? A: The summary suspension length is set by statute and cannot be extended by the court. However, a conviction results in a separate revocation, which is indefinite and can effectively extend the period during which you cannot legally drive.
Q: What is the difference between an informal and a formal reinstatement hearing? A: An informal hearing is a walk-in appointment at a Secretary of State facility, available to first-time DUI offenders. A formal hearing is a scheduled proceeding before a hearing officer, required for drivers with multiple DUI convictions or certain aggravating factors.
Q: If my DUI case is dismissed, does the suspension go away automatically? A: No. The summary suspension is an administrative action separate from the criminal case. A dismissal of criminal charges does not automatically rescind the suspension. A separate petition to rescind must be filed and granted by the court.
Q: How long does a DUI revocation last compared to a suspension? A: A suspension has a fixed end date (6 months to 3 years depending on the offense). A revocation has no automatic end date. For a first conviction, the minimum revocation period before seeking reinstatement is 1 year. For a second conviction within 5 years, it is 5 years.
Q: Does Illinois share DUI suspension records with other states? A: Yes. Illinois participates in the Driver License Compact, which means DUI-related actions on an Illinois license are reported to most other states. Driving on a suspended Illinois license in another state can trigger penalties in both states.
Q: Is there a hardship license available during a DUI revocation in Illinois? A: Illinois does not use the term “hardship license,” but a Restricted Driving Permit (RDP) serves a similar function during a revocation period. An RDP allows driving for essential purposes (work, medical, school) and requires a BAIID and Secretary of State approval.
Conclusion
Answering the question “how long is a DUI license suspension in Illinois?” requires understanding that there are actually two separate penalties: the automatic statutory summary suspension (6 to 36 months, depending on offense history and test compliance) and the court-ordered revocation that follows a conviction (indefinite, requiring a formal hearing to reverse).
Actionable next steps if you are facing a DUI suspension in Illinois:
- Mark the 46-day deadline. That is the window to petition for rescission of the summary suspension. Missing it eliminates your best option to challenge the administrative penalty.
- Apply for an MDDP immediately if you are a first-time offender and need to drive. Do not wait until the suspension takes effect.
- Begin the alcohol evaluation process early. It is required for reinstatement and takes time to complete through a state-approved provider.
- Contact an Illinois DUI attorney. The criminal case and the administrative suspension run on parallel tracks. An attorney can work both simultaneously to minimize total driving downtime.
- Budget for reinstatement costs. The $500 fee, BAIID costs, SR-22 insurance, and evaluation fees add up quickly. Planning ahead prevents delays once the suspension period ends.
