Dashcam audio recording is governed by US wiretap and eavesdropping laws — not by dashcam-specific statutes. Get this distinction wrong and you could face criminal exposure for recording a conversation you thought was protected by your dashcam's "video recording" label. Here's the complete US audio recording landscape for dashcam owners, by state and by use case.
One-Party vs Two-Party Consent: The Core Distinction
In the US, audio recording of conversations is regulated under wiretap statutes. States divide into two camps:
One-party consent states (38): Only one party to the conversation needs to consent. If you're driving and you consent, you can record without telling passengers.
Two-party (all-party) consent states (12): All parties must consent. You must inform passengers before recording audio.
The 12 Two-Party Consent States
- California (Penal Code §632 / "Invasion of Privacy Act")
- Connecticut (General Statutes §52-570d)
- Florida (Statute §934.03)
- Illinois (720 ILCS 5/14-2)
- Maryland (Courts and Judicial Proceedings §10-402)
- Massachusetts (General Laws Ch. 272 §99)
- Michigan (MCL 750.539c)
- Montana (MCA §45-8-213)
- Nevada (NRS 200.620)
- New Hampshire (RSA 570-A:2)
- Pennsylvania (18 Pa. Code §5703)
- Washington (RCW 9.73.030)
Two-party consent in these states means: recording audio of a passenger conversation without their knowledge can be illegal — potentially criminal.
How to Comply in Two-Party States
Option 1: Notice sticker (recommended)
Post a small sign in your vehicle visible to passengers: "Audio and video recording in use for safety." Most jurisdictions accept this as constructive consent — by entering the vehicle and seeing the notice, the passenger implicitly consents.
Where to place:
- Inside back-seat door window
- Center console or dashboard area visible to passengers
- For rideshare: also include in the Uber/Lyft pickup area if you display info
Option 2: Verbal notification
Tell passengers explicitly: "Just so you know, I have a dashcam that records audio in this car." Takes 5 seconds, full compliance.
Option 3: Disable audio recording
Most dashcams let you toggle audio off while keeping video on. Useful when carrying passengers in two-party states; less useful for solo drivers since the rule only kicks in with multiple parties.
The JADO G810 Pro has a one-tap audio toggle on the menu — toggle when you pick up a rideshare passenger in a two-party state.
Rideshare-Specific Implications
Rideshare drivers face the two-party consent rule constantly because they're always carrying passengers:
- Operating in two-party states (CA, FL, IL, PA, WA, MA, etc.) means every trip triggers the consent requirement.
- Crossing state lines during a trip means jurisdictional complexity — the rule applies where you are at the moment of recording.
- Both Uber and Lyft allow dashcams with the caveat that drivers comply with state law.
Default approach: post a notice sticker in the cabin year-round. Removes the per-trip consent question.
Real-World Enforcement
Two-party consent violations are rarely prosecuted as standalone offenses — usually they come up when audio recording is presented as evidence in another case. Possible outcomes:
- Evidence exclusion: Court excludes the audio from your dashcam if recorded without consent. Video typically still admissible.
- Civil liability: Passenger could sue under state privacy laws for damages
- Criminal charges: Rare but possible in particularly egregious cases (CA criminalizes intentional violation under §632)
The practical impact: most owners post a notice sticker and never have an issue. The notice-sticker compliance path is cheap and effective.
Employer-Employee Recording Rules
If you're recording audio in a company-owned vehicle that an employee drives:
- In one-party states: The employer (you) consenting is generally sufficient
- In two-party states: The employee needs to know and consent — typically through employment contract language
- Union states (CA, NY, IL, MI): Some collective bargaining agreements restrict in-cab recording without driver consent regardless of state law
For fleet managers: include dashcam audio consent language in driver employment contracts. Most legal teams have template language available.
Federal Considerations
The US federal wiretap statute (18 USC §2511) follows one-party consent. State laws can be more restrictive (the 12 two-party states are) but never less restrictive. This means:
- You always need to comply with the stricter state law where you are
- Federal-level enforcement happens for interstate violations (rare for dashcams)
- Federally regulated industries (commercial trucking under FMCSA) follow federal rules with some state overlays
Crossing State Lines
If you drive from a one-party state into a two-party state, the rules of where you are at the moment apply. Practical guidance:
- For multi-state drivers, post a notice sticker year-round — compliant everywhere
- For one-time crossings, mentally note when you enter two-party territory and either inform passengers or disable audio
- Most GPS-enabled dashcams can be configured with state-aware audio rules in firmware (rare feature; check your model)
Audio Recording as Evidence
Even where audio recording is legal (one-party states), the captured audio can be evidence:
- Statements made at the scene about fault, road conditions, or impairment
- Verbal threats or harassment from other drivers
- Passenger admissions (rare but legally significant)
- Background context — radio, ambient sounds, road noise that establishes time or weather
In a serious case, audio supplements video — sometimes the audio of an at-fault driver yelling admissions is more damning than the video of the impact.
How to Disable Audio Recording
On most JADO mirror cams: Settings → Recording → Microphone → OFF. The video recording continues; audio capture stops. Toggle is per-cam — set it once when you cross into a two-party state.
Some cams let you set audio rules by GPS region; few do this in 2026 but expect more in coming years.

Frequently Asked Questions
Is recording audio with a dash cam legal?
Yes in 38 US states (one-party consent). In the 12 two-party states (CA, CT, FL, IL, MD, MA, MI, MT, NV, NH, PA, WA), you must inform passengers before recording audio. A notice sticker satisfies most jurisdictions.
Can I record passengers without their knowledge?
In one-party states, yes — your consent as driver is enough. In two-party states, no — you must inform passengers. Posting a notice sticker provides constructive consent (passenger enters and sees the notice).
What happens if I record audio illegally in a two-party state?
Possible outcomes: the audio is excluded as evidence, you face civil liability under state privacy laws, or in egregious cases criminal charges. Video typically remains admissible.
Does audio recording in my own car require passenger consent?
In two-party states, yes. The vehicle being yours doesn't override state wiretap law. Use a notice sticker or disable audio for passenger trips.
Can I record audio at traffic stops?
Most courts allow recording police interactions in public — but state laws vary on audio specifically. For traffic stops, video recording is broadly protected; audio may have additional requirements. Verify with your state.
How does my insurance use dashcam audio?
Audio supplements video — statements made at the scene, verbal admissions, ambient context. In one-party states, freely usable. In two-party states, audio may be excluded but video remains useful.
Bottom line: Audio recording on dashcams follows US wiretap laws — one-party consent in 38 states, two-party in 12. Post a notice sticker in two-party states for constructive consent compliance, or use the audio toggle on cams like the JADO G810 Pro when carrying passengers. Video recording in your own vehicle generally doesn't have the same restrictions and is broadly legal.
