Dash cameras, or dash cams, are becoming more popular among drivers in California. They help capture accidents, prevent fraud, and provide security on the road.
Yes, dash cameras are legal in California, but they must be placed correctly and follow two-party consent laws for audio recording. Avoid blocking visibility or interfering with airbag deployment to stay compliant.
In this guide, we’ll explain everything you need to know about dash cam laws in California so you can use one without any worries.
Legal Status of Dash Cams in California
In 2011, California legalized dash cams, recognizing their potential benefits in documenting traffic incidents and promoting road safety.
However, the state has implemented regulations to ensure these devices do not compromise driver visibility or infringe individual privacy rights.
Placement and Size Restrictions

California Vehicle Code Section 26708 addresses the placement of objects on vehicle windshields and windows. While the code generally prohibits drivers from placing objects that obstruct their view, exceptions are made for dash cams, provided they adhere to specific size and placement guidelines:
- Upper Center of the Windshield: Dash cams can be mounted in the upper center area of the windshield, occupying no more than five square inches.
- Lower Right Corner of the Windshield: Devices can be placed in the lower right corner if they do not exceed seven square inches.
- Lower Left Corner of the Windshield: For the area nearest to the driver, dash cams must be no greater than five square inches if placed in the lowest corner of the windshield.
It’s essential to ensure that the dash cam’s placement does not interfere with the deployment of airbags or other safety features. Consulting with a professional installer or referring to the vehicle’s manual can guide optimal positioning.
Audio Recording and Privacy Considerations
California is a “two-party consent” state under the California Invasion of Privacy Act (CIPA). All parties involved in a conversation must consent to being recorded.
For drivers using dash cams with audio recording capabilities, informing all passengers that their conversations may be recorded is imperative. Failure to obtain consent can lead to legal consequences, including fines and potential criminal charges.
Data Retention and Usage
State regulations also dictate how long dash cam footage can be retained. Specifically, dash cams can record 30 seconds before and after a triggering event, such as a collision or sudden deceleration.
This limitation balances the benefits of recording incidents with concerns over continuous surveillance and privacy.
Admissibility of Dash Cam Footage in Legal Proceedings
Dash cam footage can be valuable evidence in legal contexts, such as traffic accident disputes or criminal cases. For the footage to be admissible in California courts, it must meet certain criteria:
- Relevance: The footage must directly pertain to the legal issue at hand.
- Legality: The recording must comply with California’s dash cam regulations, including proper placement and obtaining consent for audio recordings.
- Authentication: The footage must be verified as genuine and unaltered.
An experienced attorney can assist in ensuring that dash cam footage is appropriately presented and utilized in legal proceedings.
Benefits of Using Dash Cams
The adoption of dash cams offers several advantages to drivers:
- Evidence in Accidents: Dash cams provide an objective account of events leading up to and during a collision, which can be crucial in determining fault and facilitating insurance claims.
- Protection Against Fraud: In cases where individuals may attempt to stage accidents or submit fraudulent claims, dash cam footage can serve as a deterrent and provide proof against such activities.
- Monitoring Driving Behavior: For fleet operators or parents of teenage drivers, dash cams can be used to monitor driving habits, promoting safer driving practices.
Choosing the Right Dash Cam

When selecting a dash cam, consider the following factors:
- Video Quality: High-definition recording ensures that details such as license plates and road signs are captured.
- Field of View: A wider field allows the camera to capture more of the surroundings, providing a comprehensive perspective of incidents.
- Storage Capacity: Adequate storage ensures that footage is retained sufficiently before being overwritten.
- Additional Features: Features such as GPS tracking, night vision, and motion detection can enhance the functionality of the dash cam.
