Illinois DUI License Suspension:
The 90-Day Rule.

What Is a Statutory Summary Suspension?

A statutory summary suspension is an administrative action against your Illinois driver's license triggered automatically by a DUI arrest — not by a DUI conviction.

Under 625 ILCS 5/11-501.1, when a law enforcement officer arrests you for DUI and you either: (a) submit to chemical testing with a result of 0.08 BAC or higher, or (b) refuse to submit to chemical testing — the officer is required to issue you notice that your license will be suspended.

The suspension goes into effect 46 days after the date of the notice. During those 46 days, you retain your driving privileges. After that, unless you have successfully petitioned to rescind the suspension, your license is suspended.

The 90-Day Hearing Deadline

You have 90 days from the date of the statutory summary suspension notice to file a Petition to Rescind Statutory Summary Suspension in the circuit court where the DUI is pending.

This deadline is jurisdictional — courts have generally held that it cannot be extended, waived by agreement, or tolled. Miss the 90 days and you lose the right to contest the suspension through this mechanism, regardless of the merits of your case.

The petition must be filed in the correct court and served properly. Filing it is your attorney's job, but the 90-day clock is running from the moment you're handed that notice.

Suspension Lengths

Submitted to testing (BAC ≥ 0.08): - First suspension: 6 months - Second or subsequent suspension (within 5 years): 12 months

Refused chemical testing: - First refusal: 12 months - Second or subsequent refusal (within 5 years): 3 years

These are mandatory administrative suspensions. They begin regardless of whether the criminal DUI charge is still pending, dismissed, or resolved to a different charge. A not-guilty verdict on the DUI charge does not automatically lift a statutory summary suspension — you still had to have filed the petition to rescind on time.

Grounds to Rescind

The Petition to Rescind Statutory Summary Suspension is not a full trial of the DUI charge. The circuit court's review is limited to four issues under 625 ILCS 5/2-118.1:

1. Whether the officer had reasonable grounds to believe the driver was under the influence (i.e., whether the stop and arrest were lawful) 2. Whether the driver was placed under arrest 3. Whether the driver was given the required warnings about the consequences of refusing or failing testing 4. Whether the driver refused testing, or submitted to testing with a result of 0.08 or higher

If any of these elements is not satisfied, the suspension must be rescinded. An unlawful traffic stop — stopping a vehicle without reasonable articulable suspicion — is a common basis for rescission.

The Monitoring Device Driving Permit (MDDP)

First-time DUI offenders facing a statutory summary suspension are entitled to a Monitoring Device Driving Permit (MDDP), which allows driving during the entire suspension period — with a Breath Alcohol Ignition Interlock Device (BAIID) installed in the vehicle.

The MDDP is available as of the first day of the suspension. To get one, you must apply through the Illinois Secretary of State's office, pay the required fees, and arrange for a certified BAIID provider to install the device.

There is no grace period to apply — if you need driving privileges on day one of the suspension, the application has to be completed before the suspension begins. Your attorney should initiate this process as soon as possible after the arrest.

Note: An MDDP is not available to drivers whose suspension arises from a statutory summary suspension that follows a prior reckless homicide or aggravated DUI conviction.

How This Relates to the Criminal DUI Case

The statutory summary suspension and the criminal DUI case are parallel proceedings that share a courtroom but are legally distinct.

In practice, a hearing on the Petition to Rescind serves a strategic function beyond the license issue itself: it's often the first opportunity for defense counsel to cross-examine the arresting officer under oath, before trial, while the officer's memory is fresh and before the state has had time to prepare for detailed questioning.

Information developed in the rescission hearing can inform suppression motions in the criminal case — and occasionally reveals issues that the arresting officer's report didn't fully disclose.

This is one reason why having an attorney handle both tracks simultaneously, rather than focusing only on the criminal case, produces better outcomes.
