DUI License Suspension & the 90-Day Deadline
Your license rights are on the clock. Learn about the critical deadline and how to keep driving after a DUI arrest.
Updated May 2026
◆ Illinois Law
License suspension after a DUI arrest is governed by 625 ILCS 5/11-501.1 (Statutory Summary Suspension — Illinois Implied Consent Law). Your right to request a hearing to challenge that suspension is established under 625 ILCS 5/2-118.1, which sets the 90-day filing deadline.

◆ 90-Day Deadline
You have 90 days from the notice (usually served at your arrest) to request a hearing to fight your license suspension. Miss it and you lose this right forever.
What is the statutory summary suspension in Illinois?
The statutory summary suspension is an automatic, administrative suspension of your driving privileges imposed by the Illinois Secretary of State under 625 ILCS 5/11-501.1 when you fail or refuse chemical testing after a DUI arrest. It is separate from the criminal DUI case and applies even if the criminal charge is later reduced or dismissed. The suspension is not immediate: it begins automatically on the 46th day after you are served the notice of summary suspension at arrest, and you have 90 days from arrest to request a hearing to challenge it under 625 ILCS 5/2-118.1.
Understanding the 90-Day Deadline
This is one of the most important deadlines in your DUI case. Within 90 days of your arrest, you can request a hearing to challenge your license suspension. If you miss this deadline, you lose the right to fight the suspension—period.
At this hearing, your attorney can challenge whether the officer had proper grounds for the stop, whether you were properly advised of consequences, and whether the breath test was valid. Winning this hearing can prevent or shorten your suspension.
In DuPage County, suspension hearings are held at the DuPage County Courthouse in Wheaton. Will County hearings take place at the courthouse in Joliet. Andy Sotiropoulos has argued hundreds of suspension hearings in these courts over 25+ years of exclusive DUI defense practice—he knows the judges, the procedures, and the arguments that work.
The DUI License Timeline
- Day 1 (Arrest): You're served the notice of summary suspension and typically given a receipt that lets you keep driving temporarily. Your 90-day window to request a hearing starts.
- Day 46: The automatic statutory summary suspension begins (unless a hearing has changed the outcome)
- Day 90: Deadline to request a hearing to fight the suspension
- Month 6-12: Suspension period ends (length depends on offense and test result)
When the suspension starts: The statutory summary suspension does not take effect the day you're arrested. It begins automatically on the 46th day after you're served the notice of summary suspension. That gap is your window to act - and the reason filing for a hearing early matters.
Suspension Periods
First Offense: 6 months if you took the test, 12 months if you refused
Second Offense: 1 year if you took the test, 3 years if you refused
How Long Is a First DUI License Suspension in Illinois?
A first DUI license suspension in Illinois is 6 months if you submitted to the chemical test and it disclosed an alcohol concentration of 0.08 or more, and 12 months if you refused or failed to complete the test. Those periods run from the effective date of the statutory summary suspension, which is the 46th day after the notice is served on you, not the day of the arrest. The suspension is administrative, imposed by the Illinois Secretary of State, and it runs separately from the criminal DUI case.
"First offender" is a defined term in Illinois DUI law, not a description of how new your record feels. It means a driver with no DUI conviction or court supervision under 625 ILCS 5/11-501, and no DUI-related summary suspension or revocation under 625 ILCS 5/11-501.1, within the 5 years before the date of the current offense. Which side of that line you fall on decides the length of the suspension:
- First offender, test failed (BAC 0.08 or more): 6-month statutory summary suspension
- First offender, test refused: 12-month statutory summary suspension
- Not a first offender, test failed: 1-year statutory summary suspension
- Not a first offender, test refused: 3-year statutory summary suspension
The same status decides whether you can keep driving. First offenders are generally eligible for the Monitoring Device Driving Permit covered in the next section, which allows unlimited driving in a vehicle with an ignition interlock device installed. Whichever period applies, it can be challenged - the written request for a hearing is due within 90 days of the notice, on the grounds set out under Fighting the Suspension below.
The MDDP: Keep Driving During Suspension
The Monitoring Device Driving Permit (MDDP) is a lifeline for first-time offenders. With an MDDP, you can drive anywhere, anytime—you just need an ignition interlock device (breathalyzer) installed in your vehicle.
- Eligibility: First-time DUI offenders (some exceptions)
- Driving Allowed: Unlimited—work, school, anywhere
- Requirement: Ignition interlock device installation (~$100/month)
- How to Get It: Apply through Secretary of State after suspension begins
The MDDP means your DUI arrest doesn't have to destroy your ability to work, take your kids to school, or live your life.
Fighting the Suspension
At the suspension hearing (if requested within 90 days), your attorney can challenge the suspension on grounds including:
- The traffic stop was illegal (no reasonable suspicion)
- You weren't properly warned about suspension consequences
- The breath test wasn't properly administered
- The officer lacked probable cause for arrest
Winning this hearing can result in no suspension or a reduced suspension period. Even if you don't win, the hearing provides valuable discovery about the prosecution's case.
Getting Your License Back
After your suspension period ends, reinstatement requires:
- Completion of alcohol/drug evaluation
- Completion of any required treatment or education
- Payment of reinstatement fees ($250-$500)
- SR-22 insurance filing (high-risk insurance proof)
- Secretary of State hearing (for revocations)
If your license was revoked rather than suspended, the road back runs through a formal SOS hearing and often a Restricted Driving Permit. An Illinois license reinstatement attorney can prepare and present that case for you.
Professional License Impact
For professionals who drive for work—CDL holders, healthcare workers with patient visits, executives with client meetings—a suspended license creates immediate career complications beyond the DUI case itself. Andy factors these professional concerns into the suspension defense strategy, ensuring your ability to work is protected alongside your legal rights.

Can I drive after a DUI arrest in Illinois?
Your license typically remains valid for the first 45 days after the notice of summary suspension; the automatic suspension then begins on the 46th day. First-time offenders may be eligible for a Monitoring Device Driving Permit (MDDP), which allows unlimited driving with an ignition interlock device installed.

The Monitoring Device Driving Permit (MDDP) allows DUI offenders to drive during their suspension period with an ignition interlock device (breathalyzer) installed in their vehicle. First-time offenders are generally eligible for MDDP, which permits unlimited driving.
How do I get my license back after a DUI in Illinois?
After your suspension period ends, you must: complete any required alcohol education, pay reinstatement fees ($250-$500), provide proof of insurance (SR-22), and potentially attend a Secretary of State hearing. The process varies depending on whether it was a suspension or revocation.
How long do you lose your license for a DUI in Illinois?
It depends on your record and whether you took the chemical test. For a first offender (no DUI disposition in the prior 5 years), failing the test (BAC .08 or higher) means a 6-month statutory summary suspension, and refusing the test means a 12-month suspension. If you are not a first offender, failing the test means a 1-year suspension and refusing means a 3-year suspension. This summary suspension is imposed by the Illinois Secretary of State and is separate from any penalty in the criminal case.
What is the statutory summary suspension in Illinois?
The statutory summary suspension is an automatic, administrative suspension of your driving privileges imposed by the Illinois Secretary of State under 625 ILCS 5/11-501.1 when you fail or refuse chemical testing after a DUI arrest. It is separate from the criminal DUI case and applies even if the criminal charge is later reduced or dismissed. It begins automatically on the 46th day after you are served the notice of summary suspension, which is issued at the time of arrest.
How long is a DUI license suspension for a first offense in Illinois?
A first offender is someone with no DUI disposition in the prior 5 years. For a first offender, the statutory summary suspension is 6 months if you failed the chemical test (BAC .08 or higher) or 12 months if you refused testing. First offenders are generally eligible to keep driving during the suspension through a Monitoring Device Driving Permit (MDDP) with a BAIID (ignition interlock) device installed.
When does my license get suspended after a DUI in Illinois?
The suspension is not immediate. The statutory summary suspension begins automatically on the 46th day after you are served the notice of summary suspension at arrest. That delay is the window in which you can request a hearing to challenge the suspension - you have 90 days from the notice (usually served at your arrest) to file that request under 625 ILCS 5/2-118.1.
What is the difference between a suspended and a revoked license after a DUI in Illinois?
A suspension is temporary — your driving privileges are paused for a set period, then restored once you complete the reinstatement steps. A revocation is more serious: your license is terminated with no automatic end date, and you must apply to the Secretary of State and win a formal hearing to get it back. A first DUI arrest triggers a statutory summary suspension, but a DUI conviction triggers a revocation. That difference is one more reason a first offense is worth fighting — keeping the case to a suspension, or avoiding a conviction entirely, is far easier to recover from than a revocation.
Does refusing the breath test make my license suspension longer in Illinois?
Yes. Under Illinois's implied consent law (625 ILCS 5/11-501.1), refusing chemical testing carries a longer statutory summary suspension than failing it. For a first offense, failing the test means a 6-month suspension, while refusing means 12 months. For a second offense within five years, the periods jump to 1 year for a failed test and 3 years for a refusal. A refusal cannot be undone after the fact, so the choice made at arrest shapes the suspension you face — but it does not by itself decide the criminal case, and the suspension can still be challenged within the 90-day window.
What can I do if I don't qualify for an MDDP after a DUI in Illinois?
The Monitoring Device Driving Permit (MDDP) is generally available to first-time offenders during a statutory summary suspension. If you don't qualify — for example, because of a prior DUI or certain aggravating factors — you may still have options. A Restricted Driving Permit (RDP) can allow limited driving for work, medical, or family needs, but it requires a formal hearing with the Secretary of State and proof of hardship. Challenging the summary suspension itself within the 90-day window is another path, since a successful challenge can end the suspension entirely. Which route fits depends on your record and the facts of your arrest.
Who counts as a first offender for an Illinois DUI license suspension?
For statutory summary suspension purposes, a first offender is a driver with no DUI conviction or court supervision under 625 ILCS 5/11-501, and no DUI-related summary suspension or revocation under 625 ILCS 5/11-501.1, within the 5 years before the date of the current offense. The label decides how long you lose your license: a first offender faces a 6-month suspension for a failed chemical test and 12 months for a refusal, while a driver who is not a first offender faces 1 year and 3 years respectively. It also decides whether you can keep driving during the suspension, because the Monitoring Device Driving Permit (MDDP) is generally available to first offenders only. The status is set by your driving and conviction record, not by whether this is the first time you have been arrested.
