Dash cam use in Montana is legal, but there are specific regulations you must follow to remain compliant with state law.
Key Regulations for Dash Cams in Montana
Windshield Obstruction: Montana law requires that the driver’s windshield remain completely clear. You cannot mount a dash cam on the windshield if it obstructs, impairs, or degrades the driver’s clear view of the road. For this reason, dash cams should be installed on the dashboard instead of the windshield.
Mounting Location: The recommended and safest practice is to mount your dash cam on the dashboard, ensuring it does not block your view in any way.
Video Recording: Using a dash cam for video recording is generally protected by Montana law, provided it is not used to secretly record private property or with malicious intent (Montana Code 45-8-213). Dash cam footage is admissible in court if it is relevant and can be properly authenticated.
Audio Recording: If your dash cam records audio, you should be aware of Montana’s consent requirements. Montana is generally considered a one-party consent state for audio recordings, meaning only one person involved in the conversation needs to consent (typically, the person recording). However, best practice is to inform passengers if audio is being recorded to avoid privacy issues.
Use of Footage: Most insurance companies will consider dash cam footage as evidence when investigating claims, though discounts for dash cam use are not yet common in the United States.
