Are Dash Cams Legal? Mounting Rules, Audio Recording, and Privacy in the U.S.
Dash cams are generally legal to use in the United States, and recording video of public roads is widely done. The legal questions usually come down to two things: where you mount the camera, since some states restrict objects on the windshield, and recording audio, since conversation-recording laws vary by state and some require everyone’s consent. Rules differ from state to state and can change, so check your own state’s laws.

Windshield Mounting Laws
Many states have rules about objects that could obstruct a driver’s view through the windshield. Some spell out specific exceptions for devices like dash cams.
California is a clear example. Its Vehicle Code section 26708 allows a video event recorder in a seven-inch square in the lower corner farthest from the driver, a five-inch square in the lower corner nearest the driver (outside the airbag zone), or a five-inch square at the top center of the windshield. The same section requires a visible notice that passengers’ conversations may be recorded.
Practical tip: mounting the camera high, behind the rearview mirror, keeps it out of your line of sight and is the most common placement. See our guide on where to mount a dash cam.
Audio Recording Laws
Video of a public road is one thing. Recording conversations is another.
Federal law: one-party consent
Under federal law, 18 U.S.C. § 2511, it’s generally not unlawful for a person to record a conversation they’re part of, or where one party has given prior consent, as long as it isn’t for a criminal or tortious purpose.
Some states require all-party consent
Several states are stricter. California’s Penal Code section 632 prohibits recording a confidential communication without the consent of all parties.
What this means for drivers
- Driving alone: audio recording of yourself is generally less of a concern.
- With passengers: in all-party consent states, recording conversations without consent could be a problem. A visible notice or verbal notice helps, and turning off audio recording is the simplest option.
- Rideshare and taxi drivers: check your state’s rules and your platform’s policies on cabin cameras and audio.
Most dash cams let you switch audio recording off in the settings or app.
Privacy and Sharing Footage
- Public roads: recording what’s visible from a public road is generally lawful, but be thoughtful about posting videos online that show identifiable people or license plates.
- Private property: some parking garages and workplaces have their own camera policies.
- Footage as evidence: police and insurers often accept dash cam footage, but how it’s used depends on the case.
Our guide on are dash cams worth it covers the practical benefits and limits of footage.
Driving Outside the U.S.
Rules vary widely by country. Some countries restrict dash cam use or how footage can be shared. If you’re driving abroad, check local laws before using one.
How to Use a Dash Cam Responsibly
- Mount it in a legal spot that doesn’t block your view.
- Turn audio off unless you’re sure it’s allowed, or give passengers notice.
- Post a notice in the car if your state requires it.
- Don’t interact with the camera while driving.
- Store footage securely and share it carefully.

A compact camera that tucks behind the mirror helps keep your view clear.
- Ultracompact, key-sized dash camera goes virtually unnoticed on your windshield; automatically records and saves video of incidents with date and time (some jurisdictions regulate or prohibit use of this device)
- Easy-to-use dash camera records crisp 1080p HD video, and a wide 140-degree field of view captures details in bright and low light; automatically saves video of detected incidents (some jurisdictions regulate or prohibit use of this device)
- Built-in Garmin Clarity polarizer lens reduces windshield glare to clearly show important video details
- Save time, and avoid downloading or editing large video files with the online Vault, which automatically stores important saved video clips so you can view and share with the Garmin Drive smartphone app; you can even access high-end features, such as dash cam live view (requires a paid Vault subscription and active Wi-Fi network connection; nonpaid users can only view and download files when near the dash cam)
- Voice control lets you use spoken commands to save video and start or stop audio recording (available in English, German, French, Spanish, Italian and Swedish)
