The short answer: Dash cams are legal in all 50 states — but where you mount yours and whether you record audio depends on where you live. This guide covers every state’s windshield placement rules and audio recording consent laws so you can stay compliant and protected.
Are Dash Cams Legal in the US?
Yes. No state bans dash cams outright. In fact, courts across the country have accepted dash cam footage as evidence in traffic disputes, insurance claims, and criminal cases. The laws that do apply are about where you mount the camera and whether you can record audio.
Two rules apply everywhere:
- Your dash cam cannot obstruct your view of the road
- If you record audio with passengers in the car, state wiretapping laws may apply
Windshield Mounting Rules: What’s Legal?
Most states allow dash cams on the windshield as long as they don’t block your view. The safest universal position is behind the rearview mirror, tucked up high so the camera lens peeks through but your sightline stays clear. This position satisfies every state’s rules, including the strictest ones.
A few states have specific size limits or outright bans on windshield mounting:
| State | Windshield Mounting | Notes |
|---|---|---|
| California | Allowed in specific zones only | Max 5 sq. inches at lower driver side or top center; max 7 sq. inches at lower passenger side |
| Maryland | Allowed in specific zones only | Same size rules as California |
| Massachusetts | ❌ Not allowed on windshield | Dashboard or rearview mirror mount required |
| New Jersey | Use caution | Any windshield obstruction can be cited |
| Pennsylvania | Dashboard preferred | Windshield mounting risks a “view obstruction” citation |
| All other states | Generally allowed | Must not obstruct driver’s line of sight |
Pro tip: A suction-cup mount behind your rearview mirror keeps you compliant in all 50 states and reduces sun glare on the lens — a win-win.
Audio Recording Consent Laws by State
This is where most drivers get caught off guard. Many dash cams record audio by default. In one-party consent states, that’s fine — you’re in the vehicle, so your consent is enough. In two-party (all-party) consent states, recording audio without telling your passengers may violate wiretapping law.
Two-Party (All-Party) Consent States
In these 13 states, everyone in the vehicle must consent to being audio recorded:
| State | Law |
|---|---|
| California | Penal Code §632 |
| Connecticut | CGS §52-570d |
| Florida | Florida Statute §934.03 |
| Illinois | 720 ILCS 5/14-2 |
| Maryland | Courts & Judicial Proceedings §10-402 |
| Massachusetts | MGL c.272 §99 |
| Michigan | MCL §750.539c |
| Montana | MCA §45-8-213 |
| Nevada | NRS §200.620 |
| New Hampshire | RSA §570-A:2 |
| Oregon | ORS §165.540 |
| Pennsylvania | 18 Pa. C.S. §5703 |
| Washington | RCW §9.73.030 |
If you live in one of these states: Either notify passengers before driving (“heads up, my dash cam records audio”) or disable audio recording in your dash cam’s settings. Nearly every modern dash cam lets you turn off audio in the app or settings menu.
One-Party Consent States
In the remaining 37 states plus Washington D.C., you can legally record audio in your own vehicle without notifying passengers. You’re a party to the conversation, so your consent is sufficient.
This includes: Alabama, Alaska, Arizona, Arkansas, Colorado, Delaware, Georgia, Hawaii, Idaho, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Minnesota, Mississippi, Missouri, Nebraska, New Jersey, New Mexico, New York, North Carolina, North Dakota, Ohio, Oklahoma, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Utah, Vermont, Virginia, West Virginia, Wisconsin, Wyoming, and D.C.

3 Simple Rules to Stay Compliant Anywhere
- Mount behind the rearview mirror. This is the safest position in every state — it keeps the camera out of your direct sightline and complies with even California’s strict zone rules.
- Check your state’s audio law. If you’re in one of the 13 two-party consent states, either notify passengers or turn off audio recording in your dash cam’s settings.
- Don’t mount in the center of the windshield. A camera dead-center in your sightline can get you cited for view obstruction in any state, regardless of its size.
Frequently Asked Questions
Can police confiscate my dash cam footage?
They can request it, but generally cannot seize your camera without a warrant. Your footage belongs to you. Many dash cam brands offer encrypted microSD cards or cloud backup for added peace of mind.
Does my dash cam footage hold up in court?
Yes — in all 50 states, properly dated and time-stamped dash cam footage is admissible as evidence in civil and criminal proceedings. It’s been used successfully in insurance fraud cases, accident liability disputes, and even criminal trials.
Can my employer require dash cams in company vehicles?
Yes. Employers can legally install dash cams in fleet vehicles. However, in two-party consent states, employees typically must be notified in writing that audio is being recorded.
What if I drive through multiple states?
The laws of the state you’re in apply, not your home state. If you’re driving through California, California’s rules apply. For audio, the safest approach for long road trips across multiple states is to disable audio or have a standing disclosure to your passengers.
Is it legal to record police officers with my dash cam?
Generally yes — recording in public spaces, including traffic stops, is protected under the First Amendment. Your dash cam running during a traffic stop is legal in all 50 states.
