Dash cams—dashboard cameras—have become increasingly popular among drivers for recording road events, providing evidence in traffic disputes, and enhancing overall safety. However, if you live in or travel through Wisconsin, it’s important to understand the specific state regulations governing dash cam use to ensure you comply with the law.
Are Dash Cams Legal in Wisconsin?
Yes, dash cams are legal in Wisconsin for both personal and commercial use. Drivers are permitted to use these devices to record video and audio while operating their vehicles. Wisconsin law does not prohibit dash cams, but it includes important restrictions, especially regarding where the device can be placed inside the vehicle.
Mounting Requirements: Where Can You Place Your Dash Cam?
Wisconsin law is quite specific about dash cam placement in vehicles to avoid obstructing the driver’s view:
Windshield Mounting Restrictions:
You cannot mount the dash cam on the windshield unless it is placed directly behind the rearview mirror. Additionally, it cannot be positioned anywhere that interferes with the area swept by the windshield wipers. This essentially prohibits placements that would obstruct or distract the driver’s vision.
Recommended Mounting Location:
The safest and easiest way to comply with Wisconsin’s regulations is to mount the dash cam on the dashboard. This location avoids any conflict with windshield visibility laws and typically provides a stable recording angle.
Audio Recording and Consent
Wisconsin follows a one-party consent rule for audio recording. This means:
You may legally record audio inside your vehicle as long as you are a party to the conversation or event being recorded.
There is no requirement to notify or obtain consent from other passengers or parties recorded on the dash cam audio.
This is important because audio recording laws vary by state, and Wisconsin’s one-party consent makes it simpler for drivers to capture both video and sound legally.
Usage and Privacy Considerations
Dash cam recordings are generally admissible as evidence in court for traffic incidents, accidents, or other legal proceedings within Wisconsin, provided the footage is authentic and not tampered with.
Drivers should avoid using dash cams to record others in places where there is a reasonable expectation of privacy outside the vehicle.
Using dash cams in a way that causes distraction or obstructs the driver’s view could result in traffic citations.
Recent and Related Developments
Beyond private dash cams, Wisconsin has legislated extensively concerning dashboard-mounted cameras used by law enforcement:
By 2025, all law enforcement officers in Wisconsin are required to be equipped with dashboard cameras in patrol vehicles.
Agencies must adhere to strict data retention, privacy, and use of force policy reviews for this footage.
Violations of body or dashboard camera policies by officers can result in serious disciplinary action.
What Wisconsin Drivers Need to Know
Dash cams are legal and encouraged for safety and evidence purposes.
Mount dash cams on the dashboard or behind the rearview mirror on the windshield, never blocking the driver’s line of sight or wiper sweep.
Audio recording is legal with one-party consent—meaning if you are in the vehicle, you can record audio.
Use your dash cam responsibly, respecting privacy and safety.
Law enforcement dash cam use is regulated with strict compliance and review rules beginning 2025.
By understanding and following these regulations, Wisconsin drivers can confidently use dash cams to protect themselves and others on the road, while staying fully compliant with state laws.
