What to Do After a
DUI Arrest in Illinois.

Two Cases Start at Once

When Illinois police arrest you for DUI, two separate legal proceedings begin simultaneously:

The criminal case — charges filed in circuit court under 625 ILCS 5/11-501 (the DUI statute). This is the case most people think of.

The statutory summary suspension — an automatic administrative action against your driver's license under 625 ILCS 5/11-501.1, triggered by the arrest itself, completely independent of whether you're ever convicted.

Most people focus on the criminal charge and don't realize that the license suspension moves on its own schedule, with its own deadline, and its own hearing procedure. Missing the suspension deadline costs you your license regardless of how the criminal case ultimately resolves.

The 90-Day Deadline

Within 90 days of the DUI arrest, you (or your attorney) must file a Petition to Rescind the Statutory Summary Suspension with the circuit court if you want to contest it.

This is not a criminal hearing — it's a civil-track license matter. The judge evaluates whether: (1) the traffic stop was lawful, (2) there was proper probable cause for the arrest, and (3) whether you were properly advised of your rights regarding chemical testing.

If you miss the 90-day window, the suspension takes effect automatically: 6 months for a first offense if you submitted to testing, or 12 months if you refused. These timelines are set by statute and there is no extension mechanism.

Should You Have Refused the Breathalyzer?

Illinois operates under implied consent (625 ILCS 5/11-501.1) — by driving on Illinois roads, you're deemed to have consented to chemical testing when lawfully arrested for DUI.

Refusing to submit to a breath or blood test after a lawful arrest results in a longer suspension (12 months first offense vs. 6 months for submitting) and allows prosecutors to argue your refusal shows consciousness of guilt.

Agreeing to testing, on the other hand, produces a BAC reading the state will use as direct evidence.

There's no objectively right answer — the calculation depends on your specific circumstances, prior record, and the state of the evidence. What matters now is that you have an attorney analyzing those facts quickly.

Monitoring Device Driving Permit (MDDP)

If you're a first-time DUI offender facing a statutory summary suspension, you may be eligible for a Monitoring Device Driving Permit (MDDP). This allows you to continue driving during the suspension period — but requires the installation of a Breath Alcohol Ignition Interlock Device (BAIID) in your vehicle.

The MDDP is not automatic. There's paperwork, a fee, and coordination with the Secretary of State's office. Delays or errors in the application process can leave you without driving privileges longer than necessary.

An attorney handles this at the same time as the suspension hearing — it's part of the same case.

The Criminal Case

The criminal DUI case under 625 ILCS 5/11-501 proceeds separately. Illinois DUI can be proved either:

- By a BAC of 0.08 or higher (per se DUI) - By impairment based on officer observation, regardless of BAC (observation DUI) - By any amount of cannabis, drug, or intoxicating compound that affects driving ability (drug DUI)

Defense strategies vary dramatically by the specific facts. Common issues include: - Whether the initial traffic stop was constitutionally valid - Whether field sobriety tests were administered correctly per NHTSA guidelines - Whether the breathalyzer device was properly calibrated and maintained - Whether the arresting officer's observations support the charge - Chain of custody and lab analysis for blood draws

A not-guilty verdict, a motion to suppress, or a negotiated outcome to a non-DUI charge (like reckless driving) can protect your record and avoid the enhanced consequences that come with a DUI conviction.

DUI Consequences in Illinois

An Illinois DUI conviction carries mandatory consequences, most of which cannot be expunged:

First offense: Minimum 1-year license revocation, possible jail time (usually avoided with supervision), fines, court costs, and mandatory traffic safety school. A DUI cannot be expunged from your record.

Second offense: Minimum 5-year revocation, mandatory minimum 5 days in jail or 240 hours community service.

Felony/Aggravated DUI: Triggered by a third offense, DUI with a child in the vehicle, DUI causing great bodily harm, or other aggravating factors. Carries the possibility of prison.

Beyond the criminal penalties, a DUI conviction affects insurance rates, professional licensing, and in some cases employment — particularly in jobs requiring a commercial driver's license or security clearance.
