Understanding Dash Cam Regulations in California

Dash cams are legal in California, but their use is subject to specific regulations regarding placement, audio recording, and data privacy. Here’s a detailed breakdown of the key rules and considerations:

Mounting Requirements

• Size limits:
  • ≤ 5 square inches if placed in the upper center of the windshield
  • ≤ 7 square inches if placed in the lower right corner (passenger side).
• Safety compliance: Must avoid airbag deployment zones.
• Visibility: Cannot obstruct the driver’s view.

Audio Recording Laws

• Two-party consent: All passengers must be notified if audio is being recorded, and they can request deactivation.
• Commercial vehicles: Rideshare or taxi drivers must display visible signage about recording.

Data Privacy and Storage

• Ownership: Recorded data belongs to the driver.
• Third-party sales prohibited: A 2023 law (SB 296) bans selling in-vehicle camera footage to advertisers or data brokers.
• Storage limits: Most devices automatically overwrite old data, but California requires preserving footage from 30 seconds before and after a triggering event (e.g., collision).

Legal Admissibility in Court

Dash cam footage is admissible as evidence if:

• It’s relevant to the case (e.g., shows reckless driving or collision details).
• Obtained legally (compliant with mounting/audio rules).
• Authenticated to prove it hasn’t been altered.

Key Benefits and Risks

• Pros:
  • Strengthens insurance claims by providing objective collision evidence.
  • Deters fraud (e.g., staged accidents).
• Cons:
  • Footage showing driver negligence (e.g., speeding) can be used against them.

To comply, ensure your dash cam meets size/placement rules, notify passengers about audio recording, and regularly review storage settings. Properly used, dash cams offer valuable protection while navigating California’s roads.
