Dash cam laws by state
Updated June 2026Independently researchedNo paid placement.
Whether your dash cam is legal depends on two separate issues: where you mount it on the windshield (state-specific obstruction laws) and whether you record audio (consent laws). Most states allow windshield mounting as long as it doesn’t block the driver’s view, but California and Minnesota restrict placement to narrow zones. Video recording is almost universally permitted, but audio recording is subject to one-party or two-party consent, and in the 11 states that require all-party consent, recording without permission is illegal.
Windshield obstruction laws: where can you mount your dash cam?
Every state has rules about what you can attach to a windshield, and dash cams are usually treated like GPS units or toll passes. The general rule: don’t block the driver’s view of the road. In most states, the lower corners of the windshield or a small area behind the rearview mirror are considered safe zones. California and Minnesota are the strictest. California Vehicle Code §26708 prohibits mounting anything on the windshield except in a 5-inch-square area in the lower corner on the passenger side, or a 7-inch-square area in the lower corner on the driver’s side. Minnesota’s law is similar, limiting attachments to a 4-inch-square area in the lower corners. Using a suction cup mount outside those zones can earn you a fix-it ticket. Other states, like New York and Texas, allow attachments as long as they don’t obstruct the driver’s vision, but local enforcement varies.
Audio recording consent: one-party vs two-party states
This is where dash cam legality gets tricky. Federal law allows recording of a conversation if at least one party consents (that’s you, the driver). But 11 states go further and require the consent of all parties being recorded: California, Connecticut, Florida, Illinois, Maryland, Massachusetts, Michigan, Montana, New Hampshire, Oregon, Pennsylvania, and Washington. Hawaii and Vermont have one-party laws but some court rulings add nuance. If you live in or drive through a two-party state and your dash cam captures audio of passengers or bystanders without their knowledge, you could be violating wiretapping laws. Practical workaround: many dash cams let you disable audio recording entirely or mute the microphone. If you frequently cross state lines, turning off audio is the safest bet. Remember, video alone is fine – it’s only the sound that triggers consent laws.
Are video recordings always legal?
In nearly every case, yes. Video recording on public roads does not violate wiretapping laws because there is no reasonable expectation of privacy while driving or walking on a public street. Courts have consistently held that video-only dash cam footage is admissible and legal. There are narrow exceptions: recording inside a private vehicle with the windows up and curtains drawn might intrude on a reasonable expectation of privacy, but that’s an unusual scenario for a forward-facing dash cam. Also, some states have laws against video recording in places like school zones or near military bases, but those are rare and usually unrelated to dash cams. For everyday driving, video is your friend.
What about driving across state lines?
If your dash cam is set up for your home state’s laws, crossing into another state can create a legal gray area. The safest approach is to follow the strictest law anywhere you plan to drive. For example, if you live in Texas (one-party audio) but take a road trip through California (two-party audio), you should disable audio recording while in California. Same goes for windshield placement: if you normally mount your camera in the center of the windshield (legal in many states) but drive through Minnesota, you might get stopped. A good habit is to mount the camera in the lower corner or behind the mirror – a position that’s legal in nearly every state. Some dash cams come with adhesive mounts for the dashboard, which sidesteps windshield obstruction laws entirely.
Practical tips for staying compliant everywhere
First, know your state’s specific windshield obstruction law. Most are available on the state DMV or legislature website. If you’re unsure, mount the camera entirely on the dashboard using a sticky pad instead of a suction cup – that avoids windshield rules altogether. Second, decide whether you need audio. If your dash cam has a mic, check if it can be turned off with one button or a setting. Keep it off in two-party states. Third, don’t hide the camera; some states require that any recording device be visible to the people inside the vehicle. Finally, update yourself every few years because laws do change. This guide is an overview, not legal advice – if you have a specific concern, consult a local attorney.
Frequently asked questions
Can I get a ticket for having a dash cam on my windshield?
Yes, especially in California and Minnesota if it’s mounted outside the allowed zones. Even in other states, a police officer can cite you if they believe the camera obstructs the driver’s view. Many tickets are fix-it tickets, but they’re still a hassle.
Do I need to tell passengers I’m recording audio?
In two-party consent states like California and Florida, yes – you must inform all passengers and get their permission before recording audio. In one-party states, it’s legal to record without telling them because you are one of the parties. When in doubt, disable audio.
Is it illegal to use a dash cam in a two-party consent state if I don’t record audio?
No, video-only recording is perfectly legal in all 50 states. The consent laws apply only to audio recordings. If your camera has a microphone, make sure it’s turned off or physically disconnected.
Can I mount a dash cam on the dashboard instead of the windshield?
Usually yes. Dashboard mounting is not regulated by windshield obstruction laws because it does not attach to the glass. However, make sure it does not block your view of the road or any essential gauges. Many dash cams come with adhesive pads for this purpose.
What happens if I use my dash cam in California but I’m from a one-party state?
You are subject to California’s laws while driving there. If your dash cam records audio without passengers’ consent, you could face a civil lawsuit or, in rare cases, criminal charges under California’s wiretapping law. The best practice is to disable audio before crossing the state line.
Are there any states where dash cams are completely banned?
No state has a blanket ban on dash cams. However, several states restrict where you can mount them, and a few have specific rules about audio recording. As long as you follow placement rules and audio consent laws, you’re good everywhere.
