Dash cams are legal and widely used in Washington State, but specific rules govern how and where you can install and use them. Here’s what you need to know to stay compliant in 2025.
Mounting and Placement Rules
- Windshield Mounting: It is illegal to mount a dash cam on the windshield in Washington if it obstructs the driver’s view. The law prohibits any nontransparent material—including dash cams—that blocks the driver’s clear line of sight through the windshield.
- Dashboard Mounting: Dash cams should be mounted securely on the dashboard or in a location that does not obstruct the driver’s view. This is the safest and most compliant method.
- Size Restrictions: If a device is mounted on the windshield, it must not obscure more than a five-inch square on the driver’s side or a seven-inch square on the passenger’s side, although dashboard mounting is generally preferred to avoid issues.
Audio and Video Recording Laws
- Video Recording: Recording video of public roadways is legal and does not require consent from other parties.
- Audio Recording: Washington is an all-party consent state for audio recordings. This means you must have the consent of everyone in the vehicle before recording audio. Failing to do so can violate privacy laws and result in penalties.
- Best Practice: Inform all passengers that audio is being recorded, either verbally or with a visible sticker or sign in your vehicle.
Privacy and Legal Use
- Public Spaces: Dash cam use is generally legal in public spaces, but avoid recording private property or conversations without consent.
- Evidence in Court: Dash cam footage that is recorded legally (with proper placement and consent for audio) is admissible as evidence in Washington courts for both civil and criminal cases.
