Dash cams are legal in New Hampshire but come with strict rules on mounting and audio recording to ensure driver safety and privacy. Understanding these regulations helps drivers install devices correctly and avoid fines or inadmissible footage.
Mounting Rules
Dash cams cannot be mounted on the front windshield in New Hampshire, as state laws prohibit nontransparent materials or obstructions on the front windshield and side windows, with limited exceptions for small stickers. Instead, mount them on the dashboard where they do not block the driver’s view of the road. Rear-facing cameras are permitted, providing extra coverage without violating front glass rules.
Audio Consent Laws
New Hampshire requires all-party consent for audio recordings of conversations in vehicles, under RSA 570-A:2, making secret audio interception a felony unless everyone involved agrees. This applies to in-person talks with passengers; disable audio or notify all occupants to comply. Video-only recording faces no such consent barrier, but combined audio-video needs full approval.
Visibility and Obstruction
No device can impair clear visibility forward or to the sides, per general vehicle equipment statutes like RSA 265:95. Screens visible to the driver while driving may distract and violate rules against viewing video images. Proper placement avoids tickets and ensures footage holds up if police seize it during stops.
Commercial Vehicles
Dash cams suit fleets but must follow the same mounting and consent rules; state DOT uses them with short 3-day retention unless needed for probes. Non-obstructive dashboard installs prevent airbag interference or view blocks, common in trucking. Inform employees of recording to meet all-party consent.
Court and Evidence Use
Clear, unedited dash cam video is admissible in New Hampshire courts for accidents, reckless driving defenses, or insurance claims. Timestamps strengthen authenticity; improper audio voids that portion. Footage proves safe driving or faults others effectively.
Recent Updates
No major 2025-2026 changes to dash cam mounting, but a January 2026 bill (HB 1508) proposes shifting to one-party consent for private recordings—currently stalled. Check RSA updates yearly, as surveillance laws like RSA 236:130 limit public-way tracking but exempt personal vehicle cams.
Best Practices
- Choose suction or adhesive dashboard mounts.
- Use signs like “Dash cam in use, audio recording with consent.”
- Loop-record short clips; back up incident footage.
- Test for glare or blind spots pre-install.
Penalties for Violations
Obstruction fines start at $100; audio violations risk felony charges up to 7 years if no consent. Courts suppress non-compliant evidence, harming claims.
