Maine Dashcam Laws: Mounting Rules, Audio Recording, and Evidence (2026)

March 23, 202610 min read

Dashcams are legal and widely used in Maine. The state has no specific statute that addresses dashboard cameras, which means their use is governed by general traffic safety laws, the one-party consent wiretapping statute (15 M.R.S.A. section 710), and federal motor vehicle regulations. Whether you are a daily commuter, a rideshare driver, or a fleet operator, understanding the legal framework for dashcam use in Maine will help you stay on the right side of the law.

Are Dashcams Legal in Maine?

Yes. Maine does not have any law that prohibits the installation or use of dashboard cameras in motor vehicles. You can use a dashcam in your personal vehicle, commercial vehicle, fleet vehicle, or any other motor vehicle on Maine roads.

No Specific Dashcam Statute

Maine has not enacted specific dashcam legislation. This means there are no state-imposed requirements for:

Registration or notification of dashcam use
Specific dashcam specifications or capabilities
Mandatory dashcam usage for any vehicle class
Restrictions on where dashcam footage can be stored or shared

Because no specific prohibition exists, dashcam use falls under the general legal principle that anything not explicitly prohibited by law is permitted.

Windshield Mounting Rules

Maine law addresses windshield obstructions under 29-A M.R.S.A. section 1916, which requires that windshields provide the driver with a clear and unobstructed view. Objects affixed to the windshield that materially obstruct the driver's view may result in a traffic violation.

Best practices for mounting your dashcam in Maine:

Mount the camera behind the rearview mirror where it does not block your line of sight
Use a compact camera that takes up minimal windshield space
Ensure the camera does not obstruct any vehicle inspection stickers
Test your field of vision after installation to confirm you have a clear view in all directions
Consider a dashboard-mounted or mirror-clip style camera as an alternative to windshield suction mounts

Federal Windshield Standards

The Federal Motor Vehicle Safety Standard (FMVSS) 205, administered by the National Highway Traffic Safety Administration (NHTSA), sets requirements for automotive glazing materials. While FMVSS 205 does not directly address dashcam mounting, it establishes that windshields must allow adequate visibility.

Many modern dashcams include built-in microphones that capture conversations inside the vehicle. Maine is a one-party consent state under 15 M.R.S.A. section 710 and section 712. As the vehicle owner and operator, your presence in the vehicle satisfies the one-party consent requirement. You do not need to inform passengers that the dashcam is recording audio.

This means you can legally:

Record conversations with passengers without telling them
Capture audio during traffic stops with law enforcement
Record verbal exchanges during road rage incidents or accidents
Use a dashcam that records audio continuously while driving

When Audio Recording Becomes Problematic

While one-party consent protects you when you are in the vehicle, certain situations raise legal concerns:

Unattended vehicle recording. If your dashcam continues running while you are not in the vehicle and captures conversations between other people, you are no longer a party to those conversations. This could violate 15 M.R.S.A. section 710.
Recording in private places. Maine has separate protections for privacy in certain locations under 17-A M.R.S.A. section 511. A parked vehicle in a private garage could raise privacy issues.
Cross-state calls. If your dashcam records a phone call while driving through a two-party consent state like Massachusetts or New Hampshire, the stricter state's law may apply.

Disabling Audio Recording

If you want to avoid audio recording concerns, most dashcams allow you to disable the microphone through the camera's settings. This lets you capture video footage without recording any conversations.

Using Dashcam Footage as Evidence in Maine

Traffic Accidents and Insurance Claims

Dashcam footage is valuable evidence in traffic accident cases. Maine follows a modified comparative fault system under 14 M.R.S.A. section 156, which means a plaintiff can recover damages only if their percentage of fault does not exceed the defendant's. Clear dashcam footage showing how an accident occurred can be decisive in establishing fault.

How dashcam footage helps in accident claims:

Shows the sequence of events leading up to the collision
Captures traffic signals, stop signs, and road conditions
Records the speed and behavior of other drivers
Provides a time-stamped, objective record
Documents weather and visibility conditions, which are particularly important during Maine winters

Admissibility in Maine Courts

For dashcam footage to be admissible in Maine courts, it must meet authentication and relevance standards under the Maine Rules of Evidence. The party offering the footage must demonstrate:

The recording device was functioning properly at the time
The footage has not been altered, edited, or tampered with
The date, time, and location shown are accurate
The content is relevant to the case at hand

Maine courts have accepted dashcam footage in both civil and criminal proceedings.

Criminal Cases

Law enforcement officers in Maine increasingly rely on dashcam footage from both police cruisers and civilian vehicles. Dashcam footage can serve as evidence in:

OUI (Operating Under the Influence) prosecutions
Hit-and-run investigations
Road rage and assault cases
Traffic violation disputes
Insurance fraud investigations

Small Claims Court

In Maine small claims court (cases under $6,000 as of 2026), dashcam footage can help resolve disputes about property damage, minor collisions, and parking lot incidents. The informal nature of small claims proceedings means authentication requirements are typically less strict.

Commercial Dashcam Use in Maine

Fleet Operators and Trucking Companies

Commercial fleet operators in Maine commonly use dashcams for driver safety, accident liability protection, and regulatory compliance. The Federal Motor Carrier Safety Administration (FMCSA) does not mandate or prohibit dashcam use for commercial vehicles.

Benefits for Maine commercial operators:

Reduced insurance premiums through documented safe driving
Protection against fraudulent accident claims
Driver training and coaching using real-world footage
Compliance documentation for FMCSA audits
Evidence in workers' compensation disputes

Employee Privacy Considerations

If you operate a fleet in Maine, be aware that while one-party consent permits audio recording when the driver consents, employment law may create additional obligations. Maine has workplace privacy protections that employers should consider. Best practices include:

Including dashcam use in your company's employee handbook
Having drivers acknowledge the presence of dashcams in writing
Clearly stating how footage will be used, stored, and shared
Limiting access to footage to authorized personnel
Establishing data retention policies

Rideshare and Taxi Drivers

Rideshare drivers operating in Maine can legally use dashcams. As a rideshare driver, your presence in the vehicle satisfies the one-party consent requirement for audio recording. Some rideshare drivers post a small notice informing passengers about the dashcam. While not legally required in Maine, this practice can help avoid disputes.

Dashcams and Law Enforcement in Maine

Recording During Traffic Stops

You have the right to record police officers during traffic stops in Maine. The First Circuit Court of Appeals, which has jurisdiction over Maine, ruled in Glik v. Cunniffe (2011) that the First Amendment protects the right to record law enforcement officers performing their duties in public.

Your dashcam can continue recording during a traffic stop. You do not need to turn it off or announce that it is recording. For more about your rights when recording police in Maine, see our guide on Maine laws on recording police.

Police Requests for Dashcam Footage

Law enforcement in Maine may request your dashcam footage if you witnessed an accident or crime. You are generally under no legal obligation to provide it voluntarily. However, a court subpoena or search warrant requires compliance.

If you share footage voluntarily:

Make a copy before handing it over
Note the officer's name, badge number, and case number
Ask for documentation of the transfer
Keep the original footage as a backup

Dashcam Data Storage and Privacy

Maine Data Privacy Considerations

Maine has enacted privacy protections that may be relevant to dashcam users. The state's internet privacy law (12 M.R.S.A. section 7) restricts ISPs from using or sharing customer data without consent. Additionally, Maine's new Online Data Privacy Act (LD 1822), effective July 1, 2026, adds consumer data protections that could affect how cloud-connected dashcam services handle footage.

Best practices for dashcam data storage:

Use password-protected or encrypted storage for footage
Delete footage that is no longer needed
Be cautious about posting dashcam footage of identifiable people online
Keep footage in a secure location if it may be needed as evidence

Cloud Storage and GPS Data

Many modern dashcams upload footage to cloud storage and record GPS data. While Maine law does not specifically regulate this practice for personal use, the state's evolving data privacy framework may apply to commercial dashcam services. GPS data from your dashcam could be used in legal proceedings to establish your location at specific times.

Penalties for Improper Dashcam Use in Maine

Violation	Statute	Penalty
Windshield obstruction	29-A M.R.S.A. section 1916	Traffic citation and fine
Recording audio without consent (when not a party)	15 M.R.S.A. section 710	Class C crime: up to 5 years prison, $5,000 fine
Voyeuristic use of cameras	17-A M.R.S.A. section 511	Class D crime: up to 1 year jail, $2,000 fine
Selling interception devices	15 M.R.S.A. section 710	Class B crime: up to 10 years prison

Civil liability also applies. Under 15 M.R.S.A. section 711, victims of illegal interception can recover actual damages, punitive damages, and attorney fees.

Dashcams and Maine Insurance

How Dashcams Affect Insurance Claims

Maine follows a traditional fault-based insurance system. After an accident, the at-fault driver's insurance pays for damages. Dashcam footage can be critical in determining who caused the accident and securing fair compensation.

Insurance Discounts

Some Maine insurance providers offer discounts for vehicles equipped with dashcams, particularly for commercial fleets. Contact your provider to ask about available premium reductions.
