State-by-State Legality of Phone Dash Cams: What You Must Know

While federal law doesn’t prohibit using phones as dash cams, state and local regulations create a complex legal patchwork. These laws primarily address three concerns: windshield obstruction, distracted driving, and audio recording consent. Understanding these nuances is critical to avoid fines or invalidated insurance claims.

Windshield Obstruction Laws

Most states follow the Federal Motor Vehicle Safety Standard (FMVSS), which prohibits objects blocking more than a 5×7″ area on the driver’s side windshield. However, enforcement varies:

• California (VC §26708): Mounts must be in the lower 7″ of the windshield or 5″ on passenger side.
• New Jersey (Title 39): Allows devices only in the 5″ square adjacent to the registration sticker.
• Texas (Sec. 547.613): No specific size limits, but officers can ticket “unreasonable” obstructions.

Pro Tip: Use dashboard mounts instead of windshield mounts in restrictive states like Minnesota to avoid violations.

Distracted Driving Penalties

Even with legal mounting, interacting with your phone while driving may violate hands-free laws in 25+ states. For example:

• Touching your phone to start/stop recording in Georgia could trigger a $50 fine under HB 673 (2021).
• New York’s VTL §1225-d prohibits even glancing at a mounted device for over 2 seconds.

Solution: Use apps like Nexar that auto-record when connected to car power, eliminating manual input.

Audio Recording Consent

Twelve states require two-party consent for audio recording (e.g., Massachusetts, Washington). Violations can:

• Render footage inadmissible in court
• Trigger civil lawsuits under wiretapping laws

Workaround: Disable microphone functions in dash cam apps when driving through consent states, or post visible stickers notifying passengers of recording.

Insurance Implications

While 90% of insurers accept phone dash cam footage, some impose conditions:

• Progressive requires time/date stamps for claims
• State Farm may reject footage if the phone was illegally mounted

Always check your provider’s electronic evidence policy before relying on phone recordings for disputes.

Key Takeaway: The legality hinges on proper mounting, hands-free operation, and audio settings. When in doubt, consult your state’s DMV website or a traffic attorney for localized advice.
