Dash cams are legal in Maine, but their use is limited by general vehicle‑safety and privacy rules rather than by a specific “dash‑cam statute.” Knowing where you can mount the device, how much of your view it can block, and when you can record audio is key to staying compliant.
Where and how you can mount a dash cam
Maine does not ban dash cams, but it does require that windshields and windows remain sufficiently clear for safe driving. Under this standard:
- You may mount a dash cam on the windshield or dashboard as long as it does not materially obstruct your view of the road.
- Many states (including Maine in practice) follow the idea that small devices placed in the lower corners of the windshield are usually acceptable, but anything blocking the driver’s central line of sight can be cited as a violation.
Police can ticket you if a judge or officer finds that your dash‑cam mount or screen impairs your vision, even if the device itself is otherwise legal.
Audio recording and privacy rules
Maine does not have a specific law barring dash‑cam audio in cars, but the state is a one‑party consent state for audio recording. That means:
- You can legally record conversations in your own vehicle if you are part of the conversation, without needing to tell other passengers.
- If you are recording without participating in the conversation (for example, remotely monitoring a rental car), you may run into consent or privacy issues and should treat that as a gray area legally.
Because dash‑cam footage can be used in court or insurance claims, many drivers choose to post a small notice in the rear window or verbally inform passengers that the car is recording, both to respect privacy and to avoid disputes.
Relation to Maine’s broader surveillance law
Maine does have a law about cameras on private property, but it carves out an exception that covers dash cams. Title 33 §2001 generally prohibits placing unattended cameras or electronic surveillance on someone else’s private property without written consent or a warrant, but Part A explicitly excludes:
“The use of a camera to deter theft or vandalism of a motor vehicle when the motor vehicle is temporarily parked.”
This clarity means that running a dash cam to protect your car from theft or damage—even while parked in someone else’s lot or driveway—does not violate Maine’s private‑property surveillance statute.
Practical tips for Maine drivers
- Keep the dash‑cam mount small and low, away from the main line of sight through the windshield.
- If you record audio, assume your passengers are being recorded and consider posting a brief notice or verbal disclosure to avoid privacy complaints.
- Avoid using the camera to secretly record people in private spaces (inside homes or fenced yards) beyond what is incidentally visible from the road.
