Dash cams are legal to use in all 50 US states, but most buyers overlook key legal restrictions that can lead to fines or lawsuits. Two major pitfalls: audio recording without consent and improper windshield placement. Here is what you need to know before hitting record.

Audio Recording Laws Vary by State

Twelve states require two-party consent for audio recording: California, Connecticut, Florida, Illinois, Maryland, Massachusetts, Michigan, Montana, New Hampshire, Oregon, Pennsylvania, and Washington. In these states, recording conversations inside the vehicle without notifying passengers is illegal. Even in one-party consent states, recording audio in a private space like a car can violate wiretapping laws if passengers have a reasonable expectation of privacy. To stay safe, disable audio recording on your dash cam or inform all passengers that audio is being recorded. Many dash cams offer a simple menu toggle to turn off audio.

Windshield Placement Restrictions

Federal regulations (49 CFR 571.111) prohibit mounting objects on the windshield in the driver’s line of sight. The allowed zone is a 5-inch square in the lower corner on the passenger side or a 7-inch square in the lower corner on the driver’s side. Some states like California and Minnesota have stricter rules, allowing mounts only in a 5-inch square from the top center or lower corners. Violating these placement rules can result in traffic tickets and failed vehicle inspections. Always mount your dash cam behind the rearview mirror or in the designated corner zones to avoid obstructing your view.

Privacy Concerns When Sharing Footage

Sharing dash cam footage publicly on social media or YouTube can violate privacy laws, especially if you capture people in private situations (e.g., accidents, road rage incidents). While dash cam footage is generally admissible as evidence in court, publishing it without blurring faces and license plates may lead to civil lawsuits for invasion of privacy. In the EU, GDPR imposes strict rules on sharing identifiable footage. As a rule of thumb, only share footage with law enforcement or insurers, and blur identifiable information before posting online.

State-Specific Laws on Recording Police

In most states, you have a First Amendment right to record police officers in public, including from inside your vehicle. However, some states have laws against obstructing police or recording in certain circumstances. For example, in Illinois, it is illegal to record a police officer if it interferes with their duties. If you are pulled over, it is generally legal to record the interaction, but inform the officer that you have a dash cam running. Keep the camera visible and do not hide it, as that can be seen as suspicious.

Frequently Asked Questions

Can I get a ticket for having a dash cam on my windshield?

Yes, if the dash cam obstructs your view. Most states allow mounts only in the lower corners or behind the rearview mirror. Check your state’s specific windshield placement laws to avoid fines.

Do I need to tell passengers I have a dash cam?

In two-party consent states, you must inform all passengers if the dash cam records audio. Even in one-party states, it is best practice to notify passengers to avoid privacy disputes.

Is dash cam footage admissible in court?

Yes, dash cam footage is generally admissible as evidence in civil and criminal cases, provided it was obtained legally. However, if audio was recorded illegally, the entire video might be excluded.

The Bottom Line

Dash cams are a powerful tool for protecting yourself on the road, but legal missteps can turn them against you. Disable audio recording in two-party consent states, mount the camera in a legal spot, and think twice before sharing footage online.
