First DUI License Suspension 2026: Day-by-Day Illinois Timeline
A first DUI license suspension in 2026 does not happen on the day of the arrest. It runs on a fixed calendar, and every date on that calendar is either a defense opportunity or a defense deadline. The driver who understands the timeline can act. The driver who does not understand the timeline watches the license lapse on autopilot. This post walks the entire Statutory Summary Suspension calendar day by day under 625 ILCS 5/11-501.1, from arrest through reinstatement, with the specific action items that belong on each date.
Day 0: The Arrest and the Notice of Summary Suspension
Day 0 is the arrest date. The arresting officer serves the Notice of Statutory Summary Suspension in person. The driver signs (or refuses to sign) the notice, hands over the physical Illinois driver's license, and receives a receipt that functions as a temporary permit for the next 45 days. That receipt is not a full license. It is a bridge. Two takeaways at this moment: the 46-day clock has started on the suspension, and the 90-day clock has started on the Petition to Rescind.
Days 1-10: The Discovery Window
The first ten days are when a Chicago DUI lawyer requests preservation of the dashcam and bodycam footage, the arrest report, and the breath machine calibration logs. Chicago Police Department video is not stored forever. A written preservation letter dated within days of the arrest protects the record. This is also when the driver's insurance company will typically first learn of the arrest through a court records feed.
Day 14: File the Petition to Rescind
The Petition to Rescind Statutory Summary Suspension can be filed any time within 90 days, but filing early buys hearing dates. Cook County traffic call is congested, and a Petition filed on day 80 will not get heard before the suspension takes effect on day 46. Filed on day 14, the driver has real leverage. The petition triggers a limited hearing on four narrow issues, and it forces the arresting officer to appear and testify under oath.
Day 30: Alcohol Evaluation Started
Illinois requires a formal alcohol/drug evaluation as a prerequisite to any court supervision disposition. Judges look favorably on defendants who show up to the first court appearance with the evaluation already completed. Day 30 is a reasonable target to have the evaluation scheduled and started.
Day 45: The Last Day of Full Driving Privileges
Day 45 is the last calendar day the driver holds valid full driving privileges under the temporary permit. Cars must be moved off the street. Work commutes need to be rethought. This is also the practical deadline to install a Breath Alcohol Ignition Interlock Device if applying for a Monitoring Device Driving Permit.
Day 46: The Suspension Takes Effect
At midnight on day 46, the Statutory Summary Suspension activates automatically. The Secretary of State's records now show the driver as suspended. Any traffic stop from this point forward, even for a broken taillight, exposes the driver to a driving-while-suspended charge. For a driver who took the breath test and failed, this is a 6-month suspension. For a driver who refused, it is 12 months.
Days 46-75: The MDDP Window
First-time offenders are generally eligible for a Monitoring Device Driving Permit that allows unlimited driving with a breath alcohol ignition interlock device installed. The application, the SR-22 filing, the device installation appointment, and the fee to the Secretary of State all cluster in this window. A Chicago DUI lawyer keeps the paperwork moving so the driver is not off the road any longer than statute requires.
Day 90: The Petition to Rescind Deadline
Day 90 is the hard statutory deadline to file the Petition to Rescind. File later than day 90 and the petition is denied on procedural grounds, without any consideration of the merits. This is a bright-line rule with no forgiveness for missed calendars.
Day 46 Through Month 6 or Month 12: The Suspension Serves Out
A test-failure suspension runs 6 months. A test-refusal suspension runs 12 months. During this period the driver can drive only on the MDDP with the interlock device, or not at all if no MDDP was obtained. Any interlock violation, missed rolling retest, or high-BAC reading extends the suspension and can result in a separate criminal charge.
Day 226 (Month 6+1) or Day 411 (Month 12+1): Reinstatement Eligibility
Once the suspension term is served, the driver is not automatically reinstated. Reinstatement requires paying the Secretary of State's reinstatement fee (currently $250 for a first summary suspension, $500 if the driver was found to be a repeat offender), returning any interlock hardware if required, and clearing any outstanding financial responsibility filings. Only then does the physical license get reissued.

Why Timing Beats Everything Else
Defenses can be strong. Facts can be favorable. None of that matters if the calendar runs out first. The single most common way first offenders lose their license in Illinois is a missed deadline, not a lost hearing. Every date on the calendar above has a corresponding filing, a corresponding appearance, or a corresponding fee. Missing one shifts the whole downstream timeline. The full picture of what happens after the suspension ends and how it connects to a possible criminal conviction is covered in the Chicago DUI penalties reference.
