Illinois Stop and Identify: Refusing Isn't Obstructing

Illinois wrote a stop-and-identify statute into its Code of Criminal Procedure and never attached a penalty to it. The appellate courts have said so directly — and then drawn a sharp line between the person who refuses and the person who lies.

Illinois Stop and Identify

Refusing to give a name is not a crime in Illinois, and it is not obstructing. 725 ILCS 5/107-14 lets you demand name, address and an explanation, but creates no duty to answer. A false name is chargeable as obstructing identification, 720 ILCS 5/31-4.5, a Class A misdemeanor.

725 ILCS 5/107-14 — the demand

A peace officer, “after having identified himself as a peace officer,” may stop a person in a public place when the officer reasonably infers an offense, “and may demand the name and address of the person and an explanation of his actions.”
Questioning is conducted in the vicinity of the stop.
Stop receipt: after any stop involving a frisk or search, unless impractical or exigent, the officer must give a receipt with the reason for the stop and the officer’s name and badge number.
People v. Fernandez, 2011 IL App (2d) 100473: the section governs officers; “there is no corresponding duty in the Criminal Code of 1961 for a suspect to identify himself or herself.”

Refusing is not obstructing

Fernandez: “one cannot be convicted of obstruction merely for refusing to identify oneself.”
People v. Hall, 2021 IL App (1st) 190959, followed that rule after Baskerville: the defendant was “uncooperative and argumentative,” but refusing ID did not hinder the investigation. The charging lesson from Hall: he had physically approached the car and been pushed back twice, and the State charged only the refusal.
Resisting needs an underlying offense. 720 ILCS 5/31-1(d): no arrest for resisting unless there is an underlying offense for which the person was initially subject to arrest.

Lying is chargeable — two ways

Obstructing identification, 720 ILCS 5/31-4.5 — Class A misdemeanor. Knowingly giving a false or fictitious name, residence address or date of birth to an officer who has lawfully arrested or lawfully detained the person — or who has good cause to believe the person is a witness to a crime.
People v. Schronski, 2014 IL App (3d) 120574: the detention has to be lawful and real. A community-caretaking contact is not a detention; once the officer began field sobriety testing, it was.
Obstructing a peace officer, 31-1(a), can also reach a lie. People v. Baskerville, 2012 IL 111056: no physical act is required, and false information can obstruct — but only when it actually hinders the officer. Baskerville’s own conviction was reversed because the lie didn’t impede the traffic stop.
People v. Raby (1968)’s “physical act” reading was cut back by Baskerville. Its point that mere argument with an officer is not a crime survives.
If a false name comes after the person is already in custody, charge 31-4.5, not obstructing justice under 31-4 (In re Q.P., 2014 IL App (3d) 140436, split panel).

Drivers

625 ILCS 5/6-112: a driver must display the license on demand by an officer in uniform or displaying a badge. “Display” means handing it into the officer’s hands — holding it up to the window doesn’t count.
Petty offense, fine up to $500 (§ 6-601). No conviction if the driver produces in court a license that was valid at the time.

The federal floor underneath it

Brown v. Texas, 443 U.S. 47 (1979) — with no reasonable suspicion for the stop, a person cannot be punished for refusing to identify. If the stop fails, the identification charge fails with it.
Hiibel v. Sixth Judicial District Court, 542 U.S. 177 (2004) — a state may require a name during a lawful Terry stop, but the duty has to come from state law, not the Fourth Amendment. Stating the name satisfies it — Hiibel does not reach documents — and the request must be reasonably related to the reason for the stop.

How it plays out on the street

Traffic stop, the passenger won’t give a name. That’s not obstructing and it’s not a crime. Keep your stop moving on the driver. If the passenger does answer, with a name that doesn’t exist, ask yourself two questions before you charge: was the passenger lawfully detained (or a witness you have good cause to believe saw a crime), and can you prove the name was false? If yes, 31-4.5. If the lie actually sent you somewhere — a wrong warrant hit, a wasted records check — write that down; that’s what 31-1 obstructing requires.

Frequently asked questions

Does Illinois have a stop and identify law?

Illinois allows officers to demand name, address and an explanation during a Terry stop under 725 ILCS 5/107-14, but no Illinois statute punishes refusing to answer. Illinois appellate courts have held that merely refusing to identify is not obstructing a peace officer.

Is giving a false name to police a crime in Illinois?

Yes. Obstructing identification under 720 ILCS 5/31-4.5 is a Class A misdemeanor when a person gives a false name, address or date of birth to an officer who has lawfully arrested or detained them, or who has good cause to believe they witnessed a crime. A lie that actually hinders an officer can also be obstructing under 31-1.

Do you have to hand your license to police in Illinois?

Yes, if you are driving. 625 ILCS 5/6-112 requires a driver to display a license on demand, and defines display as handing it into the officer’s hands. It is a petty offense with a fine of up to $500.
