Dash cam use is legal in Montana, but there are specific regulations you must follow regarding placement, recording, and privacy to remain compliant with state law.
Windshield and Mounting Restrictions
Montana law requires that your windshield remain completely clear and unobstructed. You cannot mount a dash cam on the windshield if it obstructs, impairs, or degrades the driver’s clear view of the road.
| Requirement | Montana Law |
|---|---|
| Windshield mounting | Not allowed if it obstructs view |
| Recommended placement | Mount on dashboard instead |
| Legal citation | Mont. Code Ann. § 61-9-405(2)(a) |
The safest practice is to install your dash cam on the dashboard to ensure it doesn’t block your view in any way.
Video Recording Laws
Using a dash cam for video recording is generally protected under Montana law, with important exceptions:
- ✅ Legal: Recording for intended dash cam purposes (accident documentation)
- ❌ Illegal: Secretly recording private property with hidden devices
- ❌ Illegal: Recording with malicious intent
Montana Code 45-8-213 prohibits video recording of private property through hidden recording devices or with malicious intent, but dash cams used for their intended purpose do not fall under these restrictions.
Audio Recording and 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 practices include:
- Inform passengers that audio is being recorded to avoid privacy issues
- Post signage in commercial vehicles and inform all passengers verbally
- Avoid recording on private property without permission
Despite not requiring consent for audio, transparency is recommended for trust and to avoid privacy disputes.
Legal Admissibility of Footage
Dash cam footage is admissible in Montana courts if properly authenticated and relevant.
Dash cam footage can be used by Montana car accident lawyers to support testimony. Insurance companies will consider dash cam footage when investigating claims, though discounts for dash cam use are not yet common in the U.S..
Summary of Montana Dash Cam Regulations
To stay compliant with Montana law, mount your dash cam on the dashboard, be transparent about audio recording, and avoid recording private property without permission.
