Michigan Dashcam Laws: Windshield Rules, Audio Recording, and Legal Use (2026)

Dashcams are legal in Michigan. MCL 257.709 requires that any windshield-mounted camera not obstruct the driver's vision, so mounting behind the rearview mirror is the standard compliant position. In-car audio falls under MCL 750.539c, but the participant exception permits the driver to record conversations they are part of.

Dashboard cameras are legal in Michigan and have become an essential tool for documenting traffic incidents, protecting against insurance fraud, and providing evidence in accident cases. Michigan does not have a specific dashcam statute, but several existing laws govern how dashcams can be installed and used.

This guide covers windshield mounting rules, audio recording considerations, using dashcam footage as evidence, and the privacy implications of recording other drivers and passengers.

Michigan Windshield Obstruction Law: MCL 257.709

The General Rule

MCL 257.709 is the primary statute affecting dashcam placement in Michigan. The law addresses windshield obstructions in several ways:

Section 257.709(1)(a): Prohibits a "sign, poster, or other nontransparent material" on the front windshield, side windows adjacent to the driver or front passenger, or sidewings adjacent to and forward of the driver or front passenger.

Section 257.709(1)(c): Prohibits "an object that obstructs the vision of the driver of the vehicle, except as authorized in this act."

These provisions do not specifically mention dashcams. However, any device mounted on the windshield that obstructs the driver's vision could violate subsection (1)(c). The key question is whether the dashcam placement actually "obstructs the vision of the driver."

Legal Dashcam Mounting Positions

To comply with MCL 257.709, mount your dashcam in a position that does not obstruct your view of the road:

• Behind the rearview mirror: This is the most popular and safest position. The dashcam sits in an area already partially blocked by the mirror, minimizing additional obstruction.
• On the dashboard: Dashboard-mounted cameras avoid windshield attachment entirely and do not implicate the obstruction statute.
• Low on the windshield near the bottom edge: Some drivers mount cameras low on the passenger side where they do not affect the driver's sightline.

Positions to Avoid

• Center of the windshield where it blocks the driver's direct forward view
• Driver's side of the windshield in the driver's primary field of vision
• Large cameras or mounts that create significant windshield coverage
• Multiple cameras mounted across the windshield that cumulatively obstruct vision

Tinted Windshield Restrictions

MCL 257.709 also restricts window tinting. Tinted film on the front windshield may only extend 4 inches from the top. This is relevant for dashcam users because some aftermarket tinting combined with a dashcam mount in the upper portion of the windshield could create compliance issues.

Video Recording by Dashcams

Recording Public Roads Is Legal

Dashcam video recording of public roads, traffic, and events visible from the roadway is legal in Michigan. Public roads are not "private places" under MCL 750.539a, and people driving on public roads have no reasonable expectation of privacy regarding their vehicles, license plates, or driving behavior.

Your dashcam can legally record:

• Other vehicles on the road, including their license plates
• Traffic conditions and road hazards
• Accidents and near-misses
• Traffic signals and signs
• Pedestrians and cyclists on public roadways
• Police interactions during traffic stops
• Anything visible from the public road

Rear-Facing and Interior Dashcams

Rear-facing cameras that record through the back window capture the same public roadway information as forward-facing cameras and are legal.

Interior-facing cameras (common in rideshare and commercial vehicles) record the vehicle's cabin. Because a vehicle's interior can qualify as a private space depending on the circumstances, interior cameras raise additional privacy considerations, particularly regarding audio recording and passenger consent.

Audio Recording by Dashcams

The Eavesdropping Statute and In-Vehicle Audio

Many dashcams record audio by default. When the dashcam captures conversations inside the vehicle, Michigan's eavesdropping statute (MCL 750.539c) applies to the audio component.

Under the participant exception from Sullivan v. Gray, 117 Mich. App. 476, 324 N.W.2d 58 (1982), if you are in the vehicle and participating in the conversation, you can record the audio without informing your passengers. Your participation satisfies the consent requirement.

However, if you step out of the vehicle and the dashcam continues recording conversations between passengers remaining in the car, you are no longer a participant. The audio recording of their private conversation could violate the eavesdropping statute.

Best Practices for Dashcam Audio

• Keep audio enabled when you are in the vehicle. Your presence as a participant makes the audio recording legal under the participant exception.
• Consider disabling audio when lending your vehicle. If someone else drives your car with passengers, the dashcam audio would record their conversations without any participant's consent.
• Inform rideshare passengers. If you drive for a rideshare service, post a visible sign in the vehicle stating that audio and video recording is in progress. This provides notice and creates implied consent.

Dashcam Footage as Evidence

Admissibility in Michigan Courts

Dashcam footage is admissible as evidence in Michigan courts when properly authenticated. The party introducing the footage must establish:

• The recording is genuine. The footage has not been edited, altered, or manipulated.
• Chain of custody. The recording has been preserved since the event occurred.
• Relevance. The footage relates to an issue in the case.
• Accuracy. The recording accurately depicts what occurred (date, time, and location stamps help establish this).

Using Dashcam Footage in Accident Cases

Dashcam footage has become one of the most powerful forms of evidence in Michigan traffic accident cases. The footage can establish:

• Which driver ran a red light or stop sign
• The speed of vehicles before impact
• Whether a driver was distracted or impaired
• Road conditions at the time of the accident
• The sequence of events leading to the collision
• Whether a hit-and-run driver fled the scene (license plate capture)

Insurance Claims

Michigan insurance companies regularly accept dashcam footage when evaluating claims. Under Michigan's no-fault insurance system, dashcam footage can help establish:

• Fault determination for mini-tort claims (property damage up to $3,000)
• Whether an injury claim is legitimate
• The severity of an impact
• Whether road conditions contributed to the accident

Some Michigan insurance companies offer discounts for vehicles equipped with dashcams, recognizing that the footage deters fraud and speeds claims processing.

Criminal Cases

Dashcam footage can serve as evidence in criminal cases involving:

• Drunk driving and impaired driving offenses
• Reckless driving and road rage incidents
• Hit-and-run offenses
• Traffic violations
• Assault with a vehicle
• Insurance fraud

Law enforcement may request or subpoena dashcam footage from witnesses to traffic crimes. You are not required to provide footage voluntarily, but a valid subpoena or court order compels production.

Commercial Vehicle Dashcams

Trucking and Fleet Vehicles

Commercial fleet operators in Michigan widely use dashcams for driver safety monitoring, accident documentation, and liability protection. Federal Motor Carrier Safety Administration (FMCSA) regulations do not mandate dashcams, but many carriers install them voluntarily.

Commercial dashcam considerations in Michigan:

• Forward-facing cameras are standard for accident documentation
• Interior cameras monitor driver alertness and compliance
• Audio recording in commercial vehicles follows the same eavesdropping rules as personal vehicles
• Fleet operators should have written policies regarding dashcam use, storage, and access

Rideshare and Taxi Dashcams

Rideshare drivers (Uber, Lyft) and taxi operators in Michigan can use dashcams to protect themselves from false accusations, document incidents, and provide evidence for insurance claims.

For audio recording with passengers:

• Post a visible sign stating that audio and video recording is in progress
• The sign provides notice and creates implied consent
• Passengers who see the sign and continue riding have arguably consented to recording
• Both Uber and Lyft allow drivers to use dashcams but require passenger notification in jurisdictions that require it

Parking Mode and Unattended Recording

Many dashcams have a "parking mode" that records when the vehicle is parked and unattended, activated by motion detection or impact sensors. This feature captures:

• Hit-and-run damage to parked vehicles
• Vandalism and theft attempts
• Break-in attempts

Parking mode video recording is legal when the vehicle is in a public parking lot or on a public street, as there is no expectation of privacy in these areas. If the vehicle is parked in a private garage, the recording of events within the garage is governed by the property owner's consent and the private place rules.

Audio recording in parking mode can be problematic. If the dashcam records conversations of people walking past the parked vehicle, and the owner is not present to be a participant, the audio may violate the eavesdropping statute. Consider disabling audio for parking mode.
