Dash cams are legal in Illinois. There are no state laws prohibiting the use of dash cameras in private vehicles
Placement restrictions:
- The dash cam must be mounted on the driver’s side of the dashboard or windshield.
- It must not obstruct more than five square inches of the windshield on the driver’s side.
- This rule ensures the device does not impair the driver’s view or violate vehicle equipment laws.
Audio Recording: Consent Required
Illinois is a two-party consent state for audio recording.
- If your dash cam records audio, you must have the consent of all occupants in your vehicle before recording any conversations.
- Recording audio without consent is a criminal offense under Illinois law.
Video Recording and Privacy
Video recording is generally legal.
- You can record video of the road, traffic incidents, and public spaces without consent.
- If you plan to publish footage (e.g., online), blur faces, license plates, or other identifying details to protect privacy.
Recording Police Officers
You are legally allowed to record on-duty police officers in public.
- If you are pulled over, you do not have to turn off your dash cam.
- This right is protected by Illinois law and applies to all public interactions with law enforcement.
Admissibility in Court
- Dash cam footage can be used as evidence in court if it was obtained in compliance with Illinois laws—especially the audio consent requirement.
- Illegally obtained audio (without consent) may be inadmissible and could expose you to legal penalties.
