1. Windshield Placement: The Rule Almost Everyone Breaks
Most states regulate dashboard obstructions rather than cameras specifically: nothing may be mounted in a zone that blocks the driver's view. The practical pattern across states is a no-mount zone on the windshield roughly parallel to the driver — commonly cited as the area swept by the wipers, a 5-7 inch band at the bottom corners, or behind the rearview mirror.
California is the most quoted example: allowed only in a 7-inch square in the lower corner on the driver's side or a 5-inch square in the lower corner on the passenger side. Arizona, Texas and Florida take the general obstruction approach — a small camera tucked behind the mirror is universally considered compliant. The universally safe answer in all 50 states: mount behind the mirror, as high and tight as possible, tuck the cable into the headliner, and you will never have a conversation at a traffic stop.
- Safe in all states: behind the rearview mirror, inside the swept zone
- California: 7-inch square lower driver corner / 5-inch passenger corner
- Never mount mid-windshield or hang from the mirror by a clip
2. Audio Recording: The Rule That Actually Varies
Video on public roads is not a privacy problem — you have no reasonable expectation of privacy in public. Audio is different. About a dozen states require all-party consent for audio recording of conversations — the commonly cited list includes California, Connecticut, Florida, Illinois, Maryland, Massachusetts, Michigan, Montana, Nevada, New Hampshire, Pennsylvania and Washington. In those states, a cabin camera recording passenger conversations without notice can create legal exposure that has nothing to do with the video.
Practical fixes used by US drivers and fleets: disable audio recording entirely in the settings (every Phoenix unit allows one-tap audio off), post consent notices for ride-share passengers, or enable audio only where your state's law is one-party.
- ~12 all-party consent states — check before enabling cabin audio
- Ride-share drivers: in-app announcements plus window stickers
- All Phoenix models: audio recording toggle in settings
3. State Spotlights Drivers Ask Us About
Arizona: no statute banning dash cams; standard obstruction rules apply, and the behind-mirror position used by our install customers in Phoenix and Tucson is uncontroversial. Texas and Florida: camera-friendly, general obstruction language only. New York: strict windshield obstruction statute — behind-the-mirror mounting is the accepted practice. Colorado and most Mountain West states: no camera-specific rules at all. If your state is not here, the behind-mirror rule keeps you safe everywhere in the US.
One more nationwide note: footage belongs to you. Police may subpoena it, but in most circumstances they cannot simply seize a camera without legal process — a fact that has protected many drivers in disputed stops.
4. Commercial Drivers and Fleets
Truck and fleet operators add federal and insurance layers. FMCSA does not prohibit driver-facing cameras, but union agreements and state labor rules can constrain always-on cabin audio. Best practice for US fleets: video always, audio off or event-only, a written camera policy signed by drivers, and retention rules (30-90 days is typical). Insurers increasingly discount premiums for fleets with camera programs — ask your agent; the discount often exceeds the hardware cost within the first year.
5. Buying With Compliance in Mind
If you resell into the US market, stock models with a clean settings menu (audio toggle, screen-off, parking mode) and mounts that permit behind-mirror installation. Every Phoenix model ships with adhesive and behind-mirror-compatible mounts, English menus and documentation — and we answer compliance-document questions for resellers before you order, not after.
