Illinois Dash Cam Laws: What’s Legal and What’s Not

Illinois permits dash cams, but specific restrictions govern their use to ensure safety and privacy compliance. The primary law affecting dash cams is the Illinois Vehicle Code (625 ILCS 5/12-503), which prohibits obstructions on windshields.

This means your dash cam must be mounted in the lower corner of the windshield (typically the passenger side) or on the dashboard, ensuring it doesn’t block more than 6 square inches of the driver’s view. Violating this rule can result in fines, even if your camera is small.

Audio Recording and Two-Party Consent

Illinois is a two-party consent state under the Eavesdropping Act (720 ILCS 5/14-2), meaning you cannot legally record conversations without consent from all parties. If your dash cam has audio recording, you must either:

• Disable the audio feature entirely to avoid legal risks
• Notify passengers verbally or with visible signage (e.g., a sticker stating “Audio Recording in Progress”)

For rideshare drivers, this is especially critical—recording passengers without warning could lead to lawsuits or license suspensions.

Privacy Concerns in Public and Private Spaces

While recording on public roads is generally legal, private property owners (like parking garages or drive-thrus) may prohibit dash cams.

For example, filming in a toll booth or secured facility could violate trespassing or surveillance laws. Additionally, posting footage online without blurring license plates or faces might infringe on privacy rights, even if the recording itself was legal.

Practical Tips for Legal Compliance

To stay compliant:

1. Mount your dash cam correctly—use suction cups or adhesive mounts in the lower windshield or dashboard area.
2. Disable audio or provide clear notice if recording conversations.
3. Check property rules before recording in parking lots or gated communities..
